Dragon Age Origins,
Borderlands,
Call of Duty: Mordern Warfare 2,
Resident Evil 5,
Killzone 2.
Biggest disappointment for me though is both the resistances which I got with my PS3.
How can you in good conscience play MW2 when Killzone 2 is out there pretty cheap? There's a reason that KZ2 is way more critically acclaimed and has more awards than M2.
