Which Game(s) Did you Most Spent your Time On and for How Long?

[soulfly666]

Of all time would have to be Soldier of Fortune 2 Double Helix multiplayer. I would think somewhere around 2500 hours over about 4-5 years.  I have played prob 1000 hours of Quake 1 in the 1990's, and 500 hours of Battlefield 2 and Battlefield Bad Company 2 also.
