COD4 - great game, lots of fun
Assassin's Creed - pretty cool, kinda repetitive after a while but decent
Warhawk - cool online only game, worth a look. don't have the headset though.
Dirt - it's alright, but no real multiplayer kind of sucks.
Motorstorm - simple arcade-style racing. great looking game, had a good time with it.
FIFA - best game in the series that I've played. I like the game mode where it locks you on one player and you see the down the field view. Wish there was some kind of superstar mode like Madden has.
Waiting for Gran Turismo and Metal Gear. Might get Unreal Tournament soon.
Anyone played DMC yet?
