I voted for "other" since you didn't include
PC on the list!
My favourite game would have to be
Homeworld (1, Cataclysm and 2). Love the idea of RTS in 3 dimensions!
The most recent game that I've enjoyed would be
Rise of Legends.
I also remember enjoying
X-Wing v Tie Fighter, I wish LucasArts would update them. Out of all the Star Fighter sims I think theirs where the best, not too complex in the controls so you could just concentrate on the game play.
Also, it may sound kind of lame, but I also enjoy
Star Trek: Armada II, since there are quite a few good MODS for it, especially the Babylon5 MOD. And unfortunately its probably one of the only good Star Trek games out there. The latest release Star Trek Legacy is just annoying.
