Can you recommend some good Sci-Fi games for me?

Some of my all time favorites:
BioShock, Dead Space, Knights of The Old Republic 1 +2

Some others I like:
Fallout 3, Dead Rising(somewhat sci-fi), Brute Force, Alot of Star Wars games.

Can be either 360 or PC, please.

Also, Don't suggest Mass Effect, I just couldn't get into that game for whatever reason
