any xbox 360 gamers

All my friends are huge Xbox 360 fans, they play Fallout 3, CoD, Halo 3, and all those other popular online games (yes I know Fallout is single-player). I'm more of a PC gamer, I think GRID is fantastic and I'd love to get Forza 3. Of course I'm saving my money for Starcraft 2 later this year. Late 2009 is going to be chock-full of fantastic new sequels.
