which was the longest game you played that is not an RPG or multiplayer?

[Weedlab]

Smash Bros. Melee. Over 10,000 hours.
Smash Bros 64. Over 1000 hours.
Street Fighter 2 Over 1000 hours for sure but I doubt I played it more than Smash 64.
Metal Gear Solid 2 and Devil May Cry (original). I'm not sure on the hours for these but I beat them well over 200 times.

 

Note no games from this gen is included. Since I started undergrad I just don't have the time to play as I would like.
