Uncharted 1/2/3 are amazing! The first one is good, but they keep getting better, and the third is just awesome. Little big planet is alot of fun aswell if you like platforming etc. God of war is of course another great exclusive.
As for other games, Skyrim, and the Assassins Creed games are sure to keep you occupied for a while.
If you get PSN, add me up 'Leakler' if you want
