Team Fortress 2
As of 8/25/13: 214 hours. Not as much as some, I know, but I'm not really a shooter person.
My old file from '98 is still kicking, and so far I've clocked 157 hours.
239 hours as of 9/7/10. Lots of those hours spent riding around waiting for eggs to hatch. I regret nothing.
World of Warcraft
I skipped a lot of classes to play WoW, and I have nothing to show for it. My account was hacked sometime in '08. Oh well.
Animal Crossing: New Leaf
102 hours, no villager pictures, and no one has suggested a police station yet. Maybe in another 100 hours.
Monster Hunter 3 Ultimate
Just got into High Rank missions. Who knows how long it'll take to get to G Rank.
