Games with space theme I played this year:
- Transcendence
- Starcraft (I)
- Warhammer 40k: Dawn of War
- Master of Orion 1, 2, 3
- Half Life
- X-COM Collector's Edition (UFO Defense, Terror From The Deep)
(what, all those games have space theme), and maybe more, but I don't have access to my collection right now.
And from the last year I remember Freelancer, VegaStrike, and one of the remakes of Privateer (maybe Gemini Gold), and probably there were more games I don't remember right now. I have X-Wing collectors edition (X-Wing, TIE Fighter, X-Wing vs. TIE Fighter) and some part of Jedi Knight, but I think I played any of them 3 or 4 years ago last time at least.
