Which video game have you spent the most time on?

Don't know for sure, in order is something like Mario Kart 64, Super Smash Bros Melee, Unreal Tournament and Gran Turismo 3. Tought the only one I've got almost tracked is Melee, I've played about 500h on my console, not counting when I played it from friends, so I guess something like 700h.
