What game have you spent the most hours on?

[Sikachu]

CSS 651 hours since steam started keeping track...

 

[Polyg0n]

I`m guessings HoMM 3, but it might be Morrowind as well.

 

[Badong]

Original Fallout 3 has about 30 hours, and modded Fallout 3 has about 1400 hours, give or take a hundred. I don't even want to think about Counter Strike...

 

[FiveSpeedf150]

WoW for sure, although I'm sure my total hours on there are nothing compared to some of the truly hardcore players (I have only one lvl 80...)

 

[Revolutionary]

Guitar hero 3.
