I've played some of these games on PC and others on PS3, but since they are all on PS3, I'll put them on my list:
1. God Of War III
2. Red Dead Redemption
3. The Last Of Us
4. GTA V
5. Assassin's Creed II
6. Uncharted 3
7. NFS: Hot Pursuit
8. Dark Souls
9. Uncharted 2
10. Dark Souls II
Edit: I listed Demon's Souls instead of Dark Souls II, forgot that it was also avilable on PS3, played the superior PC version :P
