I've had my PS3 since early 1997. I picked up a 60 gig while they were still available. I also have a 360 Elite, so I often buy exclusive titles for the PS3, or the single player games.
My choices are:
Uncharted
Uncharted 2 (Best looking console game)
Resistance 2 (Skip Resistance)
Wipeout HD
Zen Pinball (It's pretty much Pinball FX2 for the PS3/PSN download)
Gran Turismo 5 (Stunning visuals)
inFAMOUS
God of War Collection
Afterburner: Climax (PSN)
Little Big Planet (I haven't played LBP2)
Bionic Commando
Dead Space (It's a better game than RE5)
Dirt 2 ( A solid racing title)
Pac-Man CE DX
Super Stardust (PSN)
