Eh, I don't have any of those games for my PS3(none of them appealed to me), but Ratchet & Clank Future is good fun as is Burnout Paradise(granted, I have the 360 version, but the PS3 version looks just a tiny bit better). I also enjoy Super Stardust HD quite a bit.
Waiting for some of the RPG's, Home and Little Big Planet, though.
