For the $15 I spent on this game, it's provided me with at least 30 hours of fun. It took a little while to master the controls (5-6 hours), but when I did, it was just awesome. Nintendo keeps it simple, nothing too fancy here, just a lot of fun. There are 16 tracks and 16 racers. The racers are only marginally different but the tracks provide good variety. Of the three racing games from the Nintendo 64, this one is the clear favourite. The two player mode works very well too and I've enjoyed racing with other people, even if they beat me sometimes.
