Gears of War 2- 360 Hours (I shit you not)
Battlefield Bad Company 2 - 156 Hours
Dead Island - 84 Hours
Fallout New Vegas - 65 hours
Mafia II - 36 Hours
Mortal Kombat - 34 Hours
Gears of War 3 - 25 Hours
Red Dead Redemption and Oblivion - 22 hours
FEAR 3 - 19 hours
Crimson Alliance 17 Hours
This doesn't take into account the time I have played both Oblivion and Fallout: New Vegas before I signed on for Raptr.
I also question the accuracy because some games that it says I have only played for 1 hour I KNOW I played for longer than that.
What games have you guys played the most? (if you're reading this)
