I'm a bit hard on this black sheep of the series, but it is infact a pretty decent game, and for as much as I like to tease fun at it, it's pretty good. It may not have good tracks like Super Mario Kart, Double riders like Double Dash, or online play like Mario Kart DS it does have.... um 3D graphics for the first time in the series?
Yeah that's really all the game had going for it at the time. Now it's kinda aging fast. Though I do think some of the best tracks are in Mario Kart 64, and despite being a little weak, it's still one of the N64's best.
