I've never met another person who has played this :P In my opinion it's one of the best N64 games, ranking up there with both of the Zeldas, Super Smash Bros, Mario Kart, Diddy Kong Racing, etc.
The storyline isn't exceptionally good, but it's very funny and I really enjoyed how silly the bad guys were. The ending cracks me up every time xD If you haven't played this I would recommend finding it somewhere cheap or spending the time trying to get it to work correctly on an emulator.
