Billy Hatcher has some of, if not THE greatest
boss music in a game. I dare anyone to refute this.
Anyway, the multiplayer in this game was great for just fooling around in. Grabbing powerup hats and flying around/mind controlling eggs, making a mad dash for Sonic Team and rainbow eggs, riding around on dinos and sharks... good times. I also really liked how you could download GBA minigames, lost a lot of time to NiGHTS Score Attack.
