My number one would probably have to be MGS2: Sons Of Liberty on PS2. I must have played through that game about 50 times, accumulating about 500 hours, not to mention all the VR missions in MGS2: Substance on Xbox.
My second would have to be the original Deus Ex on PC, which, by adding up all the playthroughs, I probably have about 300 total hours.
Lastly would be GTA IV. About 50 hours in single player and at least 100 hours of multiplayer with my friends.
