The only ones I know for sure is Super Smash Bros. Melee and Super Mario Kart 64. Only because those were the games my freinds and I would play every weekend when they would come over. The only single player game that comes close would be Harvest Moon (if you combined total hours spent between the N64 and Playstation versions)
Damn, 100 hours is a long time to spend playing on a game. Talk about getting your money's worth.
