You all should check out Space Engineers. Its currently Early Access on Steam for $20 and while it is still alpha, it is extremely stable for an alpha and fun to play.
Its kind of like Minecraft in space, but with better graphics, cool space physics, jetpacks, and spaceships. They just added survival mode and multiplayer mode recently and its pretty fun. You can build space stations too, all custom with different rooms for different functions.
have it now and I think a few more are getting it. Feel free to post here if you want to join us in the madness that is trying to not crash spaceships into asteroids because your reactor just ran out of uranium and now your ship has no power and oh my god why is my ship still floating at through space at the same speed with no controls ahhhhhhhh
