What is the most amount of hour's you put into a video game?

Hmm I really have no idea. I know I've spent over 500 hrs on Super Smash Bros Melee.

Halo 2 has to be around 500 hrs if not more. Halo 3 is getting around to 500 hrs. I think MOHH2 is about 300 hrs.

But yea those 4 games are my most played.
