I don't know if I'd be a great GM, since I've never GM'd a game before and I'm not too experienced with sci-fi RPs; but thank you! (^//u//^) If you have experience with it, maybe you should be GM.

I wasn't thinking in terms of large-scale space battles, necessarily, but I think that would be really interesting. What I had in mind was more of a sandbox-styled RP that in which we created and explored different alien cultures and the interactions that took place when worlds collide on this space station (I'm a sucker for slice-of-life, you may have noticed), while there was a larger over-arcing plot going on, maybe a war between two planets that slowly becomes the main focus of the RP.
That all said, I'm truly open to whatever you guys want to do, and I definitely want a part in the world-building aspect of the RP.
