Mass Effect -amazing tps/rpg
Stuntman - addictive racer but more skill involved; you will need to do all the stunts the director tells u.
Crackdown - fun sandbox game with just lots to do, plus the seconds coming out soon
Conan - a bit like god of war. Isn't the best game ever but it's quite fun if you like hack n slash gameplay
Timeshift - fun timeshifting abilities mixed with intense gunfights. This game is underrated.
