I will defend NQ on this one - partially. Enough people argued for "this is fine" both on forum and discord - that i understand why the waters get so muddy that they decide not to punish people. It pisses me off too, but i do understand logic behind it. True test will be first report which will come after this announcement.
The biggest problem i see is time they needed to react to that. If this is what we are going to expect in future - so "not on the list than fine" and week or longer to add to the list - this game for long months will be trolls feast.
Guys, it really depend on how much time one can play : )
I totally get you - 20 dolars is really cheap - price for good indie game, far cry from AAA.
But still if one have an hour or two a day 3 days of week, monthly subscription is bad idea (not to mention that playing DU is bad idea too in this case ? ).
Same if you are short of cash to spend on throwaway thing, especially when you don't even know if game will be playable on your machine. Or is playable enough to spend dozens of hours - not everyone can stomach all the missing qol stuff of beta and could be turn away after few hours after all. With current economy i wouldn't ever assume that 20 dollars is easy to come by for everyone.
in general 20EUR for 3 months sub is totally ok, other games can bill it for 1. ESO sub costs 15EUR, WoW sub costs 13EUR, I see no problems to put 20EUR price tag for 3 months sub. Devs have to get money somehow now fur further development, as 90% of new players arrived on a hype train will never pay for a 2nd month in the current state of the game : D
I honestly think $20 for three months is an incredible bargain, but I can see how many might consider it a potential waste if it turns out they don't like the game in the first week.
We realize there is some confusion regarding whether certain scenarios occurring within the game world are permitted or not, and would like to clarify these points for everyone. In short, we’d like to ask our community to use common sense when encountering issues in the game; If it looks like an exploit, smells like an exploit (do pixels smell?), or sounds like an exploit, chances are it is an exploit. Don’t DU it! Report it. (support.dualthegame.com)
We are in a testing phase, and reporting these bugs/issues is important. Abusing them may lead to sanctions against accounts, up to and including removal from the game. We will not take ignorance as an excuse, especially in the following list of scenarios. Please note this is not an exhaustive list, and we will continue to expand upon it as needed:
“ALT + F4 Emergency Brake”: We acknowledge this is not an intended game play loop that is being intentionally used by players. We do plan to counter this action in the future but do not consider it high priority at this time. At this time, we will not take action against an account for using such. [Allowed]
Parenting Ships - Dragged to PVP Space: This is a hot topic and one we wish to be very clear on. Intentionally parenting any construct without permission of the owner is not intended for game play. A fix has been rolled out that will address the ability to parent constructs together via the maneuver tool. As we have not previously clarified this point, we will not retroactively punish this abuse, as of this moment forward abusing similar bugs/tools to replicate this maneuver in its current state can result in disciplinary actions on an account. [Not Allowed]
Attacking PVP Zone from Safe Space: Our team has been investigating complaints of ships being attacked in the PVP zone from ships outside of the zone. Our investigations strongly point to sync issues between clients. We will continue to work with this feature, but recommend players consider the zone lines for PVP to be somewhat fluid and not absolute. Our version of the neutral zone! We ask that you continue to report cases with positions, but will not action accounts at this time, unless an additional exploit is discovered. [Allowed]
Overlapping engines with other elements (obscuring): A fix will be rolled out that will prevent this from occurring. No action will be taken, unless additional abuse is occurring. [Allowed]
Theft Via RDMS: RDMS permissions and settings are the sole discretion of each player. We advise you take the time to get to know and understand the system and be cautious when making a construct or element usable by unknown players, including the use of your friends list. Not every player has your best interest at heart. We can not get involved with permission based theft, whether as an individual or an organization. We encourage you to review your friends list each time you add or remove someone and ensure your construct permissions are set accordingly. The context menu options that set public access currently do not have a confirmation prompt, be careful as setting public access to said construct will allow every player in Dual Universe to go into build mode and remove/place elements and voxels. [Allowed]
Environmental Walls/Creations: Use of the environmental and voxel tools allows the manipulation of terrain on owned and unowned tiles. You may build walls or other structures up to the allowed height, however, said constructions must not:
Block access to market places or tutorials
Must abide by our Community Standards (phallic/sexual, political, religious or otherwise offensive shapes are not permitted)
Must not be placed with the intention of interfering with neighboring players. When players can not agree, the final decision on what is and is not acceptable is decided on a case-by-case basis by Novaquark staff.
Marketplace Construct Parking: Players are permitted to park at marketplaces with their transport vehicles so long as they are not preventing use to other players or obstructing entry or exit points. Vehicles whose purpose is advertising (organization, service or otherwise) must abide by the following rules.
Organizations and individuals wishing to advertise at markets may have one advertising construct per district maximum
Constructs may not be larger than “Small” sized
Constructs may not block access to any building, entry points or dispensers
Advertisements must not be placed/parented on constructs that don’t belong to you
Constructs that violate these terms will be removed from the game without warning or compensation.
Mass Manipulation in Transportation: Players who utilize bugs to bypass the weight penalty of their inventory, other players, other constructs, etc to move mass through the game are not permitted. This includes:
Adding additional mass to an already piloted ship [Fixed]
Docking mass to an already piloted ship [Fixed]
Circumventing linked container range [Fix Pending] [Not Allowed]
Item Duplication: Any method of duplicating items or resources (including quanta) is not allowed at any time. Any incidents of bugs of this nature must be reported to the support team at support.dualthegame.com [Not Allowed]
Boarding without permission: As the deployment of the docking update is pending, the boarding of other players' constructs without consent will be considered an exploit. [Not Allowed]
Offenders will be teleported away; repeat offenders may be subject to more serious repercussions.
If you are boarded by another player and wish to have them removed, please report it either by creating a ticket here or by messaging @gm through the in-game Help channel.
We do recommend you keep regular backups of your constructs in the form of blueprints in the case you lose a ship (through intended means (sale, give away etc),or undesired results such as in PVP, you can still recreate it later.
How to Blueprint (to save your ship/build):
Enter build-mode on the construct, right click anywhere on the construct and click “Create Blueprint”. The blueprint will then be generated inside your currently active inventory. It is wise to keep hold of a copy of any of your blueprints inside your personal nanopack, as these are safe and not lost upon respawning.
We realize this is not an exhaustive list, and we will expand upon it as time goes on. We also understand some members of our community feel that using a bug or exploit prior to acknowledgement by Novaquark is considered okay. We’d like to state that any intentional use of a bug or exploit will be treated harshly going forward. This is the one and only warning we will issue on this topic. Please just don’t DU it!
On behalf of the entire team, we thank you for helping us make Dual Universe a better place!
JC hasn't been griefed enough and hasn't griefed enough frankly.
It was pretty funny to watch the most recent stream when he said that he doesn't want automated turrets of any kind....
Right now the griefing is just for lulz.
Wait till territories are on the line and EVE style warfare doctrine goes into full effect - you know - when you win by utterly demoralizing your enemies and causing them to quit the game in frustration through any means necessary. You know, the same way you won at ARK, ATLAS, Empyrion etc....
While I hear what you are saying, the problem here goes way deeper and is created by NQ's inability to handle support tickets. It's one thing to ask people to create tickets but when these then go unanswered and not actioned for three or more weeks there is really no point. NQ really needs to start acting like a developer with a released game (which they are) and _quickly_ improve their support system.
And yes, they need to stop discussing and debating internally and start taking action as there is a number of serious issues around the game which will quickly become a problem as already the sense in some circles is that this is just another ARK/ATLAS grief fest.

can contain transform and\n kinematic reference information for all planetary systems in DualUniverse.\n Each planetary system is identified by a numeric identifier. Currently,\n the only planetary system, Helios, has the identifier: zero. This \"class\"\n supports the indexing ('[]') operation which is equivalent to the\n use of the 'getPlanetarySystem' method. It also supports the 'pairs()'\n method for iterating over planetary systems.\n\n An instance of the 'PlanetarySystem' \"class\" contains all reference\n information for a specific system. It supports the indexing ('[]') and\n 'pairs()' functions which allows iteration over each \"body\" in the\n system where the key is the numeric body ID. It also supports the\n 'tostring()' method.\n An instance of the 'BodyParameters' \"class\" contains all reference\n information for a single celestial \"body\" (a moon or planet). It supports\n the 'tostring()' method, and contains the data members:\n planetarySystemId - numeric planetary system ID\n bodyId - numeric body ID\n radius - radius of the body in meters (zero altitude)\n center - world coordinates of the body's center position\n GM - the gravitation parameter (g = GM/radius^2)\n Note that the user is allowed to add custom fields (e.g. body name), but\n should insure that complex table values have the '__tostring' metamethod\n implemented.\n Transform and Kinematics:\n \"World\" coordinates is a cartesian coordinate system with an origin at an\n arbitrary fixed point in a planetary system and with distances measured in\n meters. The coordinates are expressible either as a simple table of 3 values\n or an instance of the 'vec3' class. In either case, the planetary system\n identity is implicit.\n \"Map\" coordinates is a geographic coordinate system with an origin at the\n center of an identified (by a numeric value) celestial body which is a\n member of an identified (also a numeric value) planetary system. Note that\n the convention that latitude, longitude, and altitude values will be the\n position's x, y, and z world coordinates in the special case of body ID 0.\n The kinematic parameters in the reference data permit calculations of the\n gravitational attraction of the celestial body on other objects.\n Reference Data:\n This is an example of reference data with a single entry assigned to\n planetary system ID 0, and body ID 2 ('Alioth'):\n referenceTable = {\n [0] = { [2] = { planetarySystemId = 0,\n bodyId = 2,\n radius = 126068,\n center = vec3({x=-8, y=-8, z=-126303}),\n GM = 1.572199+11 } -- as in F=-GMm/r^2\n }\n }\n ref=PlanetaryReference(referenceTable)\n Collecting Reference Data:\n A combination of information from the \"Map\" screen in the DU user interface,\n and values reported by the DU Lua API can be the source of the reference\n table's data (planetarySystemId, bodyId, and surfaceArea is from the user\n interface):\n referenceTable = {}\n referenceTable[planetarySystemId][bodyId] =\n PlanetaryReference.createBodyParameters(planetarySystemId,\n bodyId,\n surfaceArea,\n core.getConstructWorldPos(),\n core.getWorldVertical(),\n core.getAltitude(),\n core.g())\n Adapting Data Sources:\n Other sources of data can be adapted or converted. An example of adapting a\n table, defined in the file: 'planets.lua', containing information on a single\n planetary system and using celestial body name as the key follows (note that\n a 'name' field is added to the BodyParameters instance transparently after\n construction, and the '__pairs' meta function is required to support the\n 'closestBody' and '__tostring' methods):\n ref=PlanetaryReference(\n {[0] = setmetatable(require('planets'),\n { __index = function(bodies, bodyId)\n for _,v in pairs(bodies) do\n if v and v.bodyId == bodyId then return v end\n end\n return nil\n end,\n __pairs = function(bodies)\n return function(t, k)\n local nk, nv = next(t, k)\n if nv then\n local GM = nv.gravity * nv.radius^2\n local bp = BodyParameters(0,\n nv.id,\n nv.radius,\n nv.pos,\n GM)\n bp.name = nk\n return nk, bp\n end\n return nk, nv\n end, bodies, nil\n end })\n })\n\n Converting Data Sources:\n An instance of 'PlanetaryReference' that has been adapted to a data source\n can be used to convert that source to simple table. For example,\n using the adapted instance shown above:\n load('convertedData=' .. tostring(ref))()\n newRef=PlanetaryReference(convertedData)\n Also See: kepler.lua\n ]]--\n--[[ START OF LOCAL IMPLEMENTATION DETAILS ]]--\n-- Type checks\nlocal function isNumber(n) return type(n) == 'number' end\nlocal function isSNumber(n) return type(tonumber(n)) == 'number' end\nlocal function isTable(t) return type(t) == 'table' end\nlocal function isString(s) return type(s) == 'string' end\nlocal function isVector(v) return isTable(v)\n and isNumber(v.x and v.y and v.z) end\nlocal function isMapPosition(m) return isTable(m) and isNumber(m.latitude and\n m.longitude and\n m.altitude and\n m.bodyId and\n m.systemId) end\n-- Constants\nlocal deg2rad = math.pi/180\nlocal rad2deg = 180/math.pi\nlocal epsilon = 1e-10\nlocal num = ' *([+-]?%d+%.?%d*e?[+-]?%d*)'\nlocal posPattern = '::pos{' .. num ..

----Older Version In Multiple formats for Learning Purposes. DU IT
Space Map with Warp Calculation
Credits to All of DU Lua Community
Requirements:
1 Dynamic Construct
1 Screen
1 Program Board
Link Screen then Core
Two Versions are available and do the same thing.
One uses variables and math with some built in functions from Lua to get the values.
One uses Functions from JayleBreak's atlas and functions to get the values.
*KNOWN BUGS*
----On fresh login, Core has to be ran one time to send Construct weight data over the server, otherwise math will be wrong.
So sit down in pilot seat one time and then run programming board. After that its always set. ---Server Bug
----Currently has Bug with Screen Flickers on half of the svg during setHTML redraw update-- 9/23 Patch
Planets are organized similar to DU ingame map and are stationary svg.

Description
An instance of the 'PlanetaryReference' "class" can contain transform and
kinematic reference information for all planetary systems in DualUniverse.
Each planetary system is identified by a numeric identifier. Currently,
the only planetary system, Helios, has the identifier: zero. This "class"
supports the indexing ('[]') operation which is equivalent to the
use of the 'getPlanetarySystem' method. It also supports the 'pairs()'
method for iterating over planetary systems.
An instance of the 'PlanetarySystem' "class" contains all reference
information for a specific system. It supports the indexing ('[]') and
'pairs()' functions which allows iteration over each "body" in the
system where the key is the numeric body ID. It also supports the
'tostring()' method.
An instance of the 'BodyParameters' "class" contains all reference
information for a single celestial "body" (a moon or planet). It supports
the 'tostring()' method, and contains the data members:
planetarySystemId - numeric planetary system ID
bodyId - numeric body ID
radius - radius of the body in meters (zero altitude)
center - world coordinates of the body's center position
GM - the gravitation parameter (g = GM/radius^2)
Note that the user is allowed to add custom fields (e.g. body name), but
should insure that complex table values have the '__tostring' metamethod
implemented.
Transform and Kinematics:
"World" coordinates is a cartesian coordinate system with an origin at an
arbitrary fixed point in a planetary system and with distances measured in
meters. The coordinates are expressible either as a simple table of 3 values
or an instance of the 'vec3' class. In either case, the planetary system
identity is implicit.
"Map" coordinates is a geographic coordinate system with an origin at the
center of an identified (by a numeric value) celestial body which is a
member of an identified (also a numeric value) planetary system. Note that
the convention that latitude, longitude, and altitude values will be the
position's x, y, and z world coordinates in the special case of body ID 0.
The kinematic parameters in the reference data permit calculations of the
gravitational attraction of the celestial body on other objects.
Reference Data:
This is an example of reference data with a single entry assigned to
planetary system ID 0, and body ID 2 ('Alioth'):
referenceTable = {
[0] = { [2] = { planetarySystemId = 0,
bodyId = 2,
radius = 126068,
center = vec3({x=-8, y=-8, z=-126303}),
GM = 1.572199+11 } -- as in F=-GMm/r^2
}
}
ref=PlanetaryReference(referenceTable)
Collecting Reference Data:
A combination of information from the "Map" screen in the DU user interface,
and values reported by the DU Lua API can be the source of the reference
table's data (planetarySystemId, bodyId, and surfaceArea is from the user
interface):
referenceTable = {}
referenceTable[planetarySystemId][bodyId] =
PlanetaryReference.createBodyParameters(planetarySystemId,
bodyId,
surfaceArea,
core.getConstructWorldPos(),
core.getWorldVertical(),
core.getAltitude(),
core.g())
Adapting Data Sources:
Other sources of data can be adapted or converted. An example of adapting a
table, defined in the file: 'planets.lua', containing information on a single
planetary system and using celestial body name as the key follows (note that
a 'name' field is added to the BodyParameters instance transparently after
construction, and the '__pairs' meta function is required to support the
'closestBody' and '__tostring' methods):
ref=PlanetaryReference(
{[0] = setmetatable(require('planets'),
{ __index = function(bodies, bodyId)
for _,v in pairs(bodies) do
if v and v.bodyId == bodyId then return v end
end
return nil
end,
__pairs = function(bodies)
return function(t, k)
local nk, nv = next(t, k)
if nv then
local GM = nv.gravity * nv.radius^2
local bp = BodyParameters(0,
nv.id,
nv.radius,
nv.pos,
GM)
bp.name = nk
return nk, bp
end
return nk, nv
end, bodies, nil
end })
})
Converting Data Sources:
An instance of 'PlanetaryReference' that has been adapted to a data source
can be used to convert that source to simple table. For example,
using the adapted instance shown above:
load('convertedData=' .. tostring(ref))()
newRef=PlanetaryReference(convertedData)

Methods:
Kepler:escapeAndOrbitalSpeed - for a given celestial body and altitude.
Kepler:orbitalParameters - for a given massless object and a celestial body.
Description
The motion of an object in the vicinity of substantially larger mass is
in the domain of the "2-body problem". By assuming the object whose motion
is of interest is of negligable mass simplifies the calculations of:
the speed to escape the body, the speed of a circular orbit, and the
parameters defining the orbit of the object (or the lack of orbit as the
case may be).
Orbital Parameters:
periapsis - the closest approach to the planet
apoapsis - the furthest point from the planet if in orbit (otherwise nil)
eccentricity - 0 for circular orbits
<1 for elliptical orbits
1 for parabiolic trajectory
>1 for hyperbolic trajectory
period - time (in seconds) to complete an orbit

DualUniverse kinematic equations
Author: JayleBreak
Usage (unit.start):
Kinematics = require('autoconf.custom.kinematics')
Methods:
computeAccelerationTime - "relativistic" version of t = (vf - vi)/a
computeDistanceAndTime - Return distance & time needed to reach final speed.
computeTravelTime - "relativistic" version of t=(sqrt(2ad+v^2)-v)/a
Description
DualUniverse increases the effective mass of constructs as their absolute
speed increases by using the "lorentz" factor (from relativity) as the scale
factor. This results in an upper bound on the absolute speed of constructs
(excluding "warp" drive) that is set to 30 000 KPH (8 333 MPS). This module
provides utilities for computing some physical quantities taking this
scaling into account.

can contain transform and\n kinematic reference information for all planetary systems in DualUniverse.\n Each planetary system is identified by a numeric identifier. Currently,\n the only planetary system, Helios, has the identifier: zero. This \"class\"\n supports the indexing ('[]') operation which is equivalent to the\n use of the 'getPlanetarySystem' method. It also supports the 'pairs()'\n method for iterating over planetary systems.\n\n An instance of the 'PlanetarySystem' \"class\" contains all reference\n information for a specific system. It supports the indexing ('[]') and\n 'pairs()' functions which allows iteration over each \"body\" in the\n system where the key is the numeric body ID. It also supports the\n 'tostring()' method.\n An instance of the 'BodyParameters' \"class\" contains all reference\n information for a single celestial \"body\" (a moon or planet). It supports\n the 'tostring()' method, and contains the data members:\n planetarySystemId - numeric planetary system ID\n bodyId - numeric body ID\n radius - radius of the body in meters (zero altitude)\n center - world coordinates of the body's center position\n GM - the gravitation parameter (g = GM/radius^2)\n Note that the user is allowed to add custom fields (e.g. body name), but\n should insure that complex table values have the '__tostring' metamethod\n implemented.\n Transform and Kinematics:\n \"World\" coordinates is a cartesian coordinate system with an origin at an\n arbitrary fixed point in a planetary system and with distances measured in\n meters. The coordinates are expressible either as a simple table of 3 values\n or an instance of the 'vec3' class. In either case, the planetary system\n identity is implicit.\n \"Map\" coordinates is a geographic coordinate system with an origin at the\n center of an identified (by a numeric value) celestial body which is a\n member of an identified (also a numeric value) planetary system. Note that\n the convention that latitude, longitude, and altitude values will be the\n position's x, y, and z world coordinates in the special case of body ID 0.\n The kinematic parameters in the reference data permit calculations of the\n gravitational attraction of the celestial body on other objects.\n Reference Data:\n This is an example of reference data with a single entry assigned to\n planetary system ID 0, and body ID 2 ('Alioth'):\n referenceTable = {\n [0] = { [2] = { planetarySystemId = 0,\n bodyId = 2,\n radius = 126068,\n center = vec3({x=-8, y=-8, z=-126303}),\n GM = 1.572199+11 } -- as in F=-GMm/r^2\n }\n }\n ref=PlanetaryReference(referenceTable)\n Collecting Reference Data:\n A combination of information from the \"Map\" screen in the DU user interface,\n and values reported by the DU Lua API can be the source of the reference\n table's data (planetarySystemId, bodyId, and surfaceArea is from the user\n interface):\n referenceTable = {}\n referenceTable[planetarySystemId][bodyId] =\n PlanetaryReference.createBodyParameters(planetarySystemId,\n bodyId,\n surfaceArea,\n core.getConstructWorldPos(),\n core.getWorldVertical(),\n core.getAltitude(),\n core.g())\n Adapting Data Sources:\n Other sources of data can be adapted or converted. An example of adapting a\n table, defined in the file: 'planets.lua', containing information on a single\n planetary system and using celestial body name as the key follows (note that\n a 'name' field is added to the BodyParameters instance transparently after\n construction, and the '__pairs' meta function is required to support the\n 'closestBody' and '__tostring' methods):\n ref=PlanetaryReference(\n {[0] = setmetatable(require('planets'),\n { __index = function(bodies, bodyId)\n for _,v in pairs(bodies) do\n if v and v.bodyId == bodyId then return v end\n end\n return nil\n end,\n __pairs = function(bodies)\n return function(t, k)\n local nk, nv = next(t, k)\n if nv then\n local GM = nv.gravity * nv.radius^2\n local bp = BodyParameters(0,\n nv.id,\n nv.radius,\n nv.pos,\n GM)\n bp.name = nk\n return nk, bp\n end\n return nk, nv\n end, bodies, nil\n end })\n })\n\n Converting Data Sources:\n An instance of 'PlanetaryReference' that has been adapted to a data source\n can be used to convert that source to simple table. For example,\n using the adapted instance shown above:\n load('convertedData=' .. tostring(ref))()\n newRef=PlanetaryReference(convertedData)\n Also See: kepler.lua\n ]]--\n--[[ START OF LOCAL IMPLEMENTATION DETAILS ]]--\n-- Type checks\nlocal function isNumber(n) return type(n) == 'number' end\nlocal function isSNumber(n) return type(tonumber(n)) == 'number' end\nlocal function isTable(t) return type(t) == 'table' end\nlocal function isString(s) return type(s) == 'string' end\nlocal function isVector(v) return isTable(v)\n and isNumber(v.x and v.y and v.z) end\nlocal function isMapPosition(m) return isTable(m) and isNumber(m.latitude and\n m.longitude and\n m.altitude and\n m.bodyId and\n m.systemId) end\n-- Constants\nlocal deg2rad = math.pi/180\nlocal rad2deg = 180/math.pi\nlocal epsilon = 1e-10\nlocal num = ' *([+-]?%d+%.?%d*e?[+-]?%d*)'\nlocal posPattern = '::pos{' .. num ..

It's not choosing the grind life, I was giving the Dev's an honest "first impression" that's all. I'll dig a little deeper into the game proper, and probably join an org to get the most of the time I am in the game. I think, for them, it would be useful to hear feedback from people in a beta, as honestly as can be done. That's why I laid out my gaming experience, and my "first impressions". First impressions are super important in life, you don't show up at a job interview in slacker attire, and then expect the boss to hire you because maybe later you'll be well dressed...
(Not saying that applies here just an example of First Impressions)
I know a lot of gamers whose first 2 hours with a game makes or breaks their interest in said gaming experience. As I have a lot more experience in games and know that maybe if I push a little harder, there is a gem to be had I'll play out the beta, but my initial feeling on the matter is not a mostly positive long term view of the game. Maybe it will change and I'll post an updated "My on going impression of Dual Universe".
Hello, it has been a long time for me, yet I still follow news of this game and communities progress.
I want to say thank you to the developers that work tediously at their stations to create the very medium by which so many stories and tales will be told.
Thank you to the supporting staff that help us with our issues on the forums, responding to tickets of all sorts of issues, be you paid or a volunteer.
Thank you to the guild leaders that have carried on through the years you've done a great job keeping people interested in the game as well as constructing mini communities that keep people active.
Thanks to all you independent contributors who endlessly pick at flaws in the rules, scratch your brains to conjure up new ideas to suggest, and keep the world of ideas turning.
Thanks to the artist's that have drawn and rendered great art works.
Even thanks to those I have clashed with in the distant past when I was active here, you've gone on to keeping people active and make it a better place when I could no longer do so. I hope all you old friends and frenemies are still doing ok regardless of who you were or are now.
Really, good job to everyone, working on the team or just a fan of the game. You should be proud.
Thank you very much for the efforts, contributions, and trying so hard.
I want to say to you all, that even though there are many heated conversations, debates, arguments even, that you are still apart of the community which is Dual Universe. You are all connected in a great web of activity and even the guy that just tricked your group into a bad deal, the guy you just argued with for 6 hours about your' org's policies, the people you just dusted in pvp; you're all brothers and sisters in the Dual Universe. I tried to think of a less corny way of saying all this, but really all that matters is I'd like to see everyone smile more, and be a little less hard on each other. Have a nice day.
Not actually true, voxels SHOULD effect element placing and they do show as effecting it within build mode, if you place voxels behind an engine etc it will turn red, which is supposed to show it has reduced output, if you look in your reports when flying the ship you will see that all the elements should have reduced effectiveness due to being blocked. This mean that whilst you ship can function, its performance is greatly reduced. How well this reduction is working in game I couldnt tell you, slightly surprised you didnt show us an image of your actually flight performance, rather than this image, which really doesnt show us much.
Trying to work out if this is a post based on actual evidence (that the output reduction is not working) or a knee jerk post from the new player.
Here is a test i did, see one engine is covered by voxels and is showing red
Here is the readout showing the element is 86% obstructed, which suggests that you conclusion that voxels do not effect element performance might be a little wide of the mark.
Can we get official NQ reply on this ? WTF is "not intended game mechanics ?" It's a sandbox, it doesn't play by intended mechanics. Discord is not a thing to get data from, I am not to about to scroll 100500 pages.
Do I get a ban for doing it ? If someone does it to my ship does he get banned ? We need a clear answer here.
PvP space is a space where killing player is possible and actually should happen.... If you enter willingly - you face consequences. If you decide to enter again - you can die again. If you enter 10 times in a row, you can die 10 times in a row. Doesn't matter if this will be same player ganking a spot or 10 different players. Doesn't matter what the balance is, how disproportional forces are, is going to pvp zone even necessary, etc. All of that is beside the point. Whoever is in the pvp zone signed in blood and tears contract to be allowed to be killed and kill by solo action of being there.
To be brutally honest - in this game if you can't run or fight, you are nothing more but flying paycheck waiting to be cashed in. if you are dying over and over again at the same spot, you are minimal effort, probably lucrative (and dumb) paycheck. End of story.
For the records, all that "doesn't matter" has an exception - exploits - those do matter, should never be used in practice and be dealt with by NQ asap.
I see it very simple - for now we build nice stuff cause its fun. PvP is not fully implemented, so even said cubes are not probably going to last. NQ will have to do something about that meta because if all the players see are meta ships and all the builders emigrated - this game will have neither graphics nor looks nor gameplay to find audience. Not to mention investment in voxel buildings going to waste. So i'm not worried and waiting for the future.
Edit: and lets be real - if they make building / playing pacifically / not pvp oriented role unsustainable, i (and probably other people too) will just emigrate to different games. Not the first time, nor the last.
Interesting you bring up Empyrion (you had probably blown up a few of the POI I built or upgraded lol). It is a decent example of some of the struggles of trying to appease the pvp-vs-builders spectrum. However it was not all a single server everyone is on. This allowed a wider audience to play the game how they wanted to play (small servers, co-ops, single pve or just creative mode), but when they make sweeping changes that only benefit one side (the pvp end), they lost momentum.
You mention their CPU addition... arguably it was one of the worst decisions they made. And as you said, it came about as an attempt to 'balance' the pvp end of things... however in doing so, it negatively impacted the creative side of things (the Builders). The devs had their view though, and refused to budge on the overwhelming negative feedback during internal testing, and pushed it out the door regardless that most all internal testers were against it and brought up bountiful arguments and alternatives to just make it a bit better without all the drawbacks alienating their creative audiences. Same thing happened with their method of making Shields require the most rarest of element in the galaxy to function. Another bad decision they ignored their internal testing group on... "it was for pvp balance".
While Empyrion does do a lot of interesting things, and has more content (so to speak)... many of its growing pains, DU could learn from. And yes, the structural integrity system is a laughable mess When they added it, it reduced almost every building into "a mound of blocks" because anything remotely creative would fall apart with just one hit. Space Engineers has ship-based integrity, which you can rip parts off for not building correctly... but that game suffers from a lot of physics issues too (maybe because of it).
DU is in a unique position I think. It has Space Engineers, Empyrion, Starship EVO, Satisfactory, and even Intersteller Rift and Astrox to draw from.... seeing 'what failed', and 'what jives'. I'm not sure it could be compared to Elite Dangerous, Star Citizen, or any of the X series... just due to those are not 'builders'.
There are some really good points and perspectives here.
Keeping in mind that this is new territory and the overall design of the universe is key to an enjoyable experience for everyone I would like to state a few things I have observed and learned from previous games that follow along some of the same concepts as this game.
The game that this reminds me the most of is Empyrion Galactic Survival. Empyrion had, and still has, some very similar challenges to its overall design. Some design challenges I think they solved pretty well, others not so well.
Similarly Empyrion was significantly focused on the pvp part of the game. Of course the most important thing to pull off for successful pvp is balance so you can keep it fair and possibly even more importantly, interesting. This is particularly challenging in a game where you don't have pre-designed mechanisms of warfare as people are excellent at finding workarounds to the ways the game was "intended" to be played and with a game that is completely open ended like this is it's virtually impossible to prevent any possible exploit creative people that play these games can think up.
One of the first major issues in Empyrion pvp was the same thing we see happening on here in DU. In order to be competitive, people are just building bigger and thicker bricks because at the end of the day pvp skill takes a back seat to it being mostly a numbers game, whoever has the most blocks and guns wins. There were a couple of ways this was addressed in Empyrion, first they implemented a system to discourage this type of building with a system they called "cpu" which basically had a certain amount of points that were available for a build and each item you added has a point value. Once you pass 100% of the available points you start to see a proportional degradation to the performance of your build.
The second thing they did that had a big impact was the implementation of shields. Shields used two consumables to function, one was a mineral you would mine and the other was power to recharge. These changes greatly reduced the number of bricks flying around because they simply wouldn't move because they were over the max point value so much. The shield actually allowed a ship that was not specifically designed for pvp to survive long enough to escape the pvp area and get to a pve zone.
Something Empyrion could do better is with the zone design. I don't have any great ideas to offer here. This is a hard balance to maintain as well. If you give people a pathway where they can completely avoid the pvp zone it kills the pvp experience. On the other hand if you force everyone to go through pvp you are going to hurt the player base that just enjoys the building or other non-pvp aspects of the game.
Empyrion has "systems" that you warp into and in some of those systems you may have all PVE areas and some all PVP and others a mixture of both. One key to the systems layout are the warp paths. They use some that are one way and some that are longer so you have to have a bigger warp drive to use them and this allows some gating to help keep things under control for balance purposes although it definitely has an impact on the game immersion.
Another aspect that I really think DU could learn from Empyrion is the Creativity Mode. You could always start the game in single player and select creative mode and it would allow you everything available to build with. Then you can save your blueprint and use it in game. I don't understand why they don't implement something similar DU, it sorely needs it, it would only improve the ship designs in the game and make it more imersive.
Another game this reminds me of is Satisfactory. I think DU has this aspect of the game down pretty well without overdoing it. I always thought that Empyrion made this part of the game way too easy. Don't get me wrong though there is still some big improvements that I think that can be made with this part of the game as well. Its definitely a bit sloppy in the tier design.
The game physics of DU is done really well too. Punishing but doable. I know it is probably really complex to implement properly but I would love to see some level of structural integrity implemented as well. Empyrion did not do this well but it also didn't have as robust of a physics engine as DU. I could just imagine a big ship tearing itself apart by someone making the structural framework too thin and placing gigantic thrusters on it and someone doing a turn and burn too fast. I know I am probably asking too much with this though. I always wished while playing Empyrion that it had the impact on flying from the physics of the ships like DU does and it's one of the many reasons I switched over to DU.
Mining in this type of game is obviously a major part and I think it's particularly important to keep it interesting. The game I believe that has done this best is Elite Dangerous. It has the perfect ratio of complexity to reward. Think core mining…
Anyway I am getting off subject of the OP here so I will stop but as with any game in development you hit a point where your decisions have a major impact on the future course of the game and to me it looks like that's where Dual Universe is currently. The more successful indy games I have seen, and I play almost exclusively indy games, have all listened carefully to the feedback of their communities and made smart decisions based off that feedback.
I wish Novaquark the best, I know it has to be the most challenging genre of game to be designing. Good luck!
I don't think it's as bleak as that - but I do think that the devs have more ideas about WHAT they want rather than HOW they want it.
The devil is in the details and we just don't have them - especially in how territory control will work, what will and won't be PvP.
The fact that we do not know what will happen to Alioth is something I just can't wrap my mind around. Will it be pvp? Will it stay pve? What is this nonsense about half and half? How can we be committed into building large structures if we don't know what will happen to them?
I see it very simple - for now we build nice stuff cause its fun. PvP is not fully implemented, so even said cubes are not probably going to last. NQ will have to do something about that meta because if all the players see are meta ships and all the builders emigrated - this game will have neither graphics nor looks nor gameplay to find audience. Not to mention investment in voxel buildings going to waste. So i'm not worried and waiting for the future.
Edit: and lets be real - if they make building / playing pacifically / not pvp oriented role unsustainable, i (and probably other people too) will just emigrate to different games. Not the first time, nor the last.

Ark is not voxel based in the way DU is, is it a game purely based on elements you build with and thus technically vastly more simple. As previously said "I spend a small fortune" means very little in this regard if your focus is fairly basic games computing wise. No one here will deny DU drives your PC harder that most other games and for good reason, while yes, over the course of beta optimization will improve performance , this is what beta is for, but it will always be more demanding.
NQ is aware that the game needs these optimizations and it is something they are working on (as they have said several times). That said, this is not a console level game and your hardware will need to do work.
Back to @Tashkin
For reference, I run a 3700X with 2080, 32GB 3200 RAM and NVMe storage running at 1440p. CPU usage is around 65%, GPU at 75-85% with temperatures sitting around 75 Celcius overall (all fan cooled, no water) when running DU. FPS around markets is roughly 28-35 fps and elsewhere mostly capped at 60. In my in-game circle this is the general experience and I know several people running te game on 3rd gen Intel even quite comfortably.
Unfortunately I could not see the DXdiag file but from what you said I take it you do keep your gear up to date but from the symptoms you describe I frankly suspect there is some sort of hardware issue in play here, possible GPU or PSU which is triggered by the game. If I were in your position I would try and find a ways to test this with replacement hardware to see if that can exclude hardware as a possible cause. Specs wise your system should not have any issues running the game at all and if the spike is as bad as you say it is then yes, from what I know now I'd suspect a hardware issue.
It is easy to say "DU is breaking my hardware" when in reality DU is exposing/triggering a fault which is breaking your hardware
I like these two comments a lot actually. and I agree.
What we currently see in space is purely PVP, it's limited because the mechanics are half baked and there are no current countermeasures but I trust NQ will bring those in over time. People who cry about players shooting at haulers need to stop, I mean seriously. This is not griefing and by entering the game and flying your ship through space you by default consent to the possibility of being attacked. No ifs or buts here.
I think planetside PVP will be the gamechanger like Anderson said. I also think that it will not be the mechanic us "law abiding" citizens should fear as it will indeed be what will give the PVP groups what they want/need and by that their attention will shift. From the little information we know I'd say it will be expensive but fairly easy to build solid defenses in case the occasional rogue groups tries to go around and attack random groups on the ground but I expect that to be the rare exception more than a rule.
Territory warfare will be _very_ complex and costly for those attacking and so they would prefer to direct their efforts toward where they can actually get a fight worth their time I'd imagine
