The idea of farming, food and water as a survival mechanism in particular, has come up a lot in the forums. I personally think needing to eat/drink to survive would add little more to the game than a little bit of realism and a lot of really frustrating scenarios: For example, you are a explorer mapping the surface of a planet, you are making great progress but - BAM - you run out of food, and all your great work is lost! Besides, not needing to eat as we know it could be possible in a world with nanoformers and FTL travel.
 
What I suggest is that farming and consumables be in the game - but not be essential to survive. My Idea how this could work is medicine. A player could devote their skill tree to go and learn to farm various herbs and crops to make medicines and similar products, which could heal you or boost certain stats for a period of time. For instance, you could get injured in the game - either by accident, or from surviving an attack of some kind. You could either (A) wait for your health to regenerate very very slowly - or go to a clinic and buy medicine from another player to heal yourself quickly. This would add a great dynamic to the game -  both in the way of career options and the economy. Perhaps different medicines are needed to heal different sorts of damage - you would need a different treatment for surviving a spaceship crash vs. getting shot with a laser. There should also be negative "status effects" - like radiation sickness, for example. You could either wait until you recover or die/respawn, or you could get treated with some medicine/consumable. This idea would add a great dynamic to the universe, and add the need for hospitals and doctors in player-built settlements.

What I had in mind for airless planets, is even if players don't "breath", it would still prove interesting for game play. For example, the lack of air could mean that the "space only" engines would work (and atmospheric engines would not), but you would have to change the design to compensate for gravity. Or another example would be that mining would be easier on airless worlds, as there is no foliage or topsoil, and finding and extracting ores would be easier. Airless planets should also have low gravity, to keep with scientific fact - airless worlds would likely have no air due to a lack of gravity preventing them from accumulating an atmosphere.

I too am very keen on the idea of having numerous types of stellar objects.
I don't really care for a meteorite or a comet or other flying projectiles in space - however I can't think of anything I would like more than to live on a planet with a lovely binary star system on the horizon.
 
As far as airless planets go, I am not too sure, but I believe with the players helmet on, they will be able to go onto an airless planet with no problems. I don't know that there is any breathing mechanic in game requiring a player to keep canisters of oxygen in their inventory. However if there is a need for a player to stock up on oxygen and a system for reproducing it whilst in space, then an airless planet will work just like space I imagine (Could be cool, but could also add a level of difficulty some don't like?).
 
An all water planet is definitely a cool idea, but as there isn't too much confirmed in the way of water mechanics and when any true water mechanics will be implemented, an all water planet may not work too well witch current mechanics. However I do like the idea of one!
Gas giants definitely sounds cool! Makes me think of Avatar the movie. How the main planet was a gas giant and the planet where the movie was set was actually a moon of the gas giant. Would be truly spectacular for viewing purposes!
 
For the most part, everything you have said does sound plausible to implement (however, after launch for most of it no doubt). I really like everything you have said as it would add a certain Star Trek sort of immersion and realism. It will probably all be a means of when, and if, NQ decide to implement it.

Also, welcome to the forums.

It could sure look good, although my first example would be Star Wars. 

I like your idea about the black holes, but my view on wormholes stands. Wormholes should be a random phenomenon, but should be an essential part to building stargates and similar things. The idea would be that to unlock the technology to build a stargate you must find a wormhole and study it (scan, send probes, collect radiation or particles, etc). Only then will your organization have the technology to build a stargate. This tech should be trade-able, so one, science/technology devoted organization could find a wormhole and then sell that tech to others. 
 
The idea of "stabilizing" a wormhole is a good one, But I think the stabilizing procedure could be done to one or both ends of a wormhole, so you could have one fixed entrance and a shifting exit - ideal for explorers. Or you could stabilize both ends as a cheaper, but choiceless (in regard to location) alternative to building a stargate.

To give the world in Dual Universe a bit more life, I think that there should be a bit more than just the planets and asteroids shown in trailers, but a bit more "stellar diversity", if you will. All these thing obviously won't be implemented at launch, and may not even be practical to implement.
 
Planets: There have already been several types of planets shown in trailers / discussed, and they have all been rocky, earth-sized planets. I personally think there should be various types of planets beyond the variation in biomes
Rocky Planets (similar to earth, as shown) Gas Giants, with many asteroids / small planets orbiting them. The gas within them should apply pressure and crush any ship that goes too deep in, possibly to collect the gas for something Airless planets - planets with no air, like earth's moon Liquid planets - planets with all liquid and no land, buildings will have to either float or be underwater Stars: There should be various types of stars, of varied temperatures and sizes, as well as several "oddball" stars
Neutron Stars - Very Heavy stars, remnants of smaller supernovae Pulsars - Stars that emit radio / radiation pluses, could be used for navigation White / Brown dwarf stars - small stars, burning very dimly Binary Star Systems - Two stars orbiting each other  
Nebulae: Nebulae should solar-system sized, with stuff in them (asteroids, etc). Engines should behave differently because of the gas, and the gas itself should be a resource to harvest and use/sell.
 
Black Holes: Found in deep space, they should behave much like real ones, with intense gravity and an event horizon. I do not know what the advantages of going near one would be, but they would have be worth the risk. Perhaps some rare particle radiated by black holes?
 
Comets / Meteor Storms: Small rocks / chunks of ice traveling at high speed through space. Would pose a threat of impact to large ships / stations, and planets, if they are big enough not to burn up.
 
Wormholes: Going into the realm of Sci-Fi, wormholes would act like natural stargates, connecting to another wormhole somewhere. They should be unstable, collapsing and re-forming elsewhere often
 
There could be any number of stellar phenomena in the game, fictional or otherwise, and I think they would add a nice touch of diversity throughout the emptiness of space

I just started discussion about research through exploration and discovery. Although that idea has lot of potential problems/challenges it would fit with black holes. Extreme unusual condition due to ridiculous gravity etc. could mean some research could only be done close enough to black hole (better research = closer to event horizon) which would be risky with potential reward. Otherwise they would mostly mean area you want to stay away from. Any large moving objects like comets could be hard on server and it might be considered annoying if you ship gets destroyed by random event from game rather than combat with other real players for example. 
 
For wormholes, maybe instead of having random wormhole send you to random place they could be strategic locations where you could build a special star-/jumpgate to stabilize it that could send ships to locations within certain range without need for gate on the other end, or just work as normal gate with longer range. In either case they could be important strategic locations that spark either diplomacy and cooperation or wars for control of the wormhole. What military organisation wouldn't love the ability to drop a fleet in any system on some region of space without caring about gates on that system.
