I for one found Resistance: Fall of Man, Uncharted, and Ratchet and Clank Future to all be very fun for the time I've played them. Haven't got a chance to try Warhawk or DMC4 but they both looked good IMO. It also does have a good number of games that, while multiplatform, are worth picking up if you only have a PS3. Hell, I don't even own the system and don't plan to and can find understandable reasons to purchase one or at least have a friend who does.
