Be wary of twesterm's comment, ModNation Racers is very good if you are into that sort of game. Once you get the drifting down, it plays sublimely. We've had many, many hours of play out of that game.
As for others? How about:
3D Dot Heroes, Batman, Brutal Legend, Demon's Souls, Dragon Age, InFamous, Fallout 3, Mini Ninjas, MotorStorm 2 (not 1, it's not good), Prince of Persia, Ratchet & Clank games, Read Dead Redemption, Soul Calibur IV, Street Fighter IV, Uncharted 1&2, Valkyria Chronicles.
That's off the top of my head, and many may not suit. Fortunately, there are many others. Might I also suggest checking out the PSN games: there's a ton of good stuff on there now.
