300 is peanuts for me on Diablo II, I've also spent more than that on Gran Turismo 4 for sure and also Baldur's Gate II with the expansion. Counterstrike and Age of Empires II are almost guaranteed to be at least close to 300 hours each.
FFX and XII as well when I think of it!
I know I know, I'm a sad, sad individual...
