I think we can all agree on this.
IMO it's going to be our player based in-game videos of actual game-play that would do the trick.
Seamless game-play (waging war), across a system with at least 9 unique and diverse, true scale moons/planets. Each with its own environment, some more challenging than others, but all uniquely beautiful.
Warp-jump at near light speed across vast distances of space, and immerse yourself with the fully Newtonian physics based flight model.
*edit.....Enjoy all this with up to 200 other space nerds!
blah-blah....Yeah that's all freaking awesome, but how is it actually going work as a game?
9 planets, 3 factions.....
3 Space-Stations per planet?
3 Factories/processing plants per planet?
What would motivate me to attack some faction's Hauler? Cause I'm poor and resources are scarce?
As @Arkenbrien said, Looking forward to what we and you guys come up with, after some play-testing.
