007 Quantum of Solace 600 hours....
Was the only FPS I had at first and played it a lot, WAW is at like 200 or so hours and MWR is catching of to Quantum of Solace.
Brawl is currently my 2nd most played at 500 hours.
And Animal Crossing City Folk is up there too at 350 hours
Edit: I completely forgot about MH3, that is on It's way to the top and will get there easily. Over 500 hours already and doesn't look to be slowing down.
