Haha u need a list of good ps3 games (exclusives)? Unless u have...unusual taste, then i don't see how ur ps3 will be just sitting around.
Play Uncharted 2, Metal Gear Solid 4, inFAMOUS, LittleBigPlanet, Killzone 2, Resistance 1&2, Ratchet and Clank 1&2 in that order. Sony undeniably has an excellent exclusive game library. And they're only gaining more and more great exclusives in 2010+...God of War III, Gran Turismo 5, Heavy Rain, MAG, Last Guardian, Twisted Metal PS3, Agent (Rockstar games ps3 exclusive), White Knight Chronicles, and so on. Just give ur new investment a fair chance, it won't disappoint...Enjoy!
