This game rules! My fifth favorite Sonic game! Your asking what the mistakes are? Well, when Sonic and Knucles talk, their eyes move up and down. Some of the stupid stuff (but funny) is when Sonic dies, he spins around like he is dancing and says, "Oh no." in a perfectly calm voice. And when Knucles falls off of a clif he screams, "AHHHHHHHHHHHHHHHHHHHHW" and it really made me laugh. If you want to laugh really loud, when you are facing Sonic (when you are knucles) when he says, "I've had enough of this!", hit him right then. Then it will sound really stupid. "I've had enough of this,Oh no!" And when you race sonic (as tails) when he passes you he says, "HOWWAY (no, i'm serious, he says HOWWAY instead of HORRAY)!" or "Cya later Tails!" But when you pass him, he says, "HEY HEY HEY!" it is so freakin funny! Or he says, "Alright Tails!" But, this game is still very awesome. The game play rocks! And how come I am the only one who notices the dumb and funny stuff in the Sonic Adventure seires?
