What game have you rack up the most hours playing?

[dharh]

Everquest: Over 1 year (8760 hours) played.
Eve Online: 2144 hours (according to steam)
Star Trek Online: 271 hours
Skyrim: about 150-200 hours
Minecraft: 100 hours or so.

Any final fantasy game is easily at minimum 80+ hours
FF6 and FF7 ive probably done couple hundred hours each due to multiple playthroughs.
Each of the Zeldas is probably quite a bit, up until the N64+ era where I stopped playing through them multiple times.
I play Zelda 1 and Zelda: LTTP at least once a year.
