Since I and the community have very little knowledge of the game, I'm gonna post my Ideas; Sorry if any are all ready implemented, but hey, if they are "Great minds think alike"
Idea 1: Territory System.
I understand there is already one, however I'd like it so, if you claim like 6 planets that are relatively close together, instead of needing to mine for the ores, you should be able to build freely how ever; it will deplete the resources on the planets. I feel if there is a mining system it will take along time to build massive ships etc.
Idea 2: Expanding on the Territory System.
You should be able to setup a zone around your planet(s), to which if a ship that is not in your clan or a friendly clan, it will play an audio file like "You are in restricted space" etc or even a YouTube clip you upload.
Idea 3: Organization/Clan system
Again, I understand that their is one already, I have created Starfleet Federation . But You should be able to declare war with certain clans and propose peace etc.
Idea 4: Shielding
I actually study physics, and feel there should be more than one type of shielding if any. These could include;
Shields to protect you from lasers.
Shields to protect you from physical weapons like missiles and bullets.
Shields to protect you from (Even tho its a bit extreme) Emps or Natural effects from deep space.
Idea 4: Specialized Weapons
I feel you should also be able to have different types of weapons, to name a few;
Laser Guns (For the star wars nubs - ha movie wars
Bullets (With different caliber)
Long Range Torpedoes
Idea 5: Peace Mode, I feel some times, especially in a game like this, I will want to fly my ship with no violence, so maybe you can activate a peace mode where; you cant attack others, and others cant attack you, damage your stuff etc.
Idea 6: Basic character customization - I think this is self explanatory, maybe clothing and all that would be a nice touch.
I hope this has created a few ideas.
