Metal Gear solid 4

Uncharted 1,2 and probably 3 I haven't completed it.
Littlebigplanet 2 and 1
God of War 3
The Last of Us
Assasins Creed IV: Black Flag (ignore the assassin part its fucking boring, the pirate bit is incredible)
Far Cry 3.
I heard No No Kuni is good but I haven't played it.

Metal Gear Solid HD Collection and Metal Gear Solid 4 (does not come with the collection unfortunately but it's cheap now)
Red Dead Redemption
Demon Souls (ps3 exclusive, Dark souls 1+2 can be obtained for PS3 or PC as well)
Little Big Planet (PSN)
Fallout 3
Arkham Asylum (this franchise has like 4 games and only 1 is bad from what I've heard. Maybe try some buyer reviews)
Assassin's Creed 2
Grand Theft Auto: San Andreas (PSN)
Suikoden 2 (PSX game on PSN)

I'm sure there's more but this should be more than enough to keep you busy.
