Oblivion with at least 2000 hours.
Skyrim around 300 hours.
Enemy Territory: Quake Wars approx. 300 hours
Bad Company 2 +150 hours
Then a bunch of games at around 100 hours (Two Worlds II, Fallout 3, Dragon Age, Demon's Souls, Red Dead, Dragon's Dogma etc)
EDIT: now that I think of it, Dragon Age wasn't full priced though. My PC version was pirated and PS3 version cost only around 30 Euro.
