Republic Commando: this game is one of my soft spots, great single player campaingn, one of the few games where the starting weapon is one most useful weapon in the game by virtue of being 3 weapons in one, and a squad that was fun to be around
Starwars Battlefront 2: Great game as well except the space battles left a lot to be desired. The campaingn was ok but the real heart of the game
Jade Empire: one of the few decidedly western style games that use eastern settings and concepts. A bit shallow for an RPG it was a blast to play the story was enjoyable and the characters entertaining. Using martial arts that you keep and upgrade as your primary form of fighting battles instead of weapons that you swap out every couple of hours was a really cool change.
Freespace 2: proably the best space combat game that I have played ever.
