This game is a lot like Mario 64 (then again that's not a bad thing) but it has a great multiplayer mode.
Graphics: 9 Excellent, even to this day it is fairly pretty and I love the animals and characters.
Sound: 8 I love the tropical-ish soundtrack and even the "voices" and sound effects are fairly good. Bonus points for the catchy intro rap (i love that song).
Controls: 7 Works pretty good but the aiming can be a bit off at some times and jumps are slow and are way too sensitive.
Entertainment: 9 This game is fun in the single player and minigames but is uber fun in the multiplayer and never gets old, ever.
Overall: 8 This game has always been in the shadow of its superior: Mario 64. But it deserves props for being a great game in its own right.
