I see no reason why every quest should be resolved in the same dull enviroment, don't tell me that there aren't any small settlements out there, or other cities. The game wasn't rewarding exploring the galaxy at all, side-quests were chores, although the way they ended was usually done well, but that has everything to do with the story and nothing to do with the enviroment. Make the game look as thrilling and awesome as the story is.
But especially the planets annoyed me, yes it's ok if some of them are lifeless rocks, those exist as well, but if a planet is described as one with an extremely lush ecosystem with huge insects and stuff, and when I land all I see is mountains with a grass texture, I feel ripped off. Some planets even put in a randomly placed group of wierd animals for no apperant reason (I remember a group of gazelle-like creatures with arms), then I really think: what the hell are you trying to do here? Are you mocking me? If you describe a planet like it's a really awesome place, actually make it look like it's description when you actually go there. If you don't, you're just lying to your players.
How far in the future will it be then?
