Sound- 8.5 out of 10- The sound in this game is just average. There are car hitting sound and powerup sounds.
Replay Value- 9 out of 10- This is were the game really shines. Since there's so many different part to buy you always want to go back and buy different parts.
Overall- 9 out of 10- This game is a great racing game. I think the only downside to this game is that there's no save feature, there's just passwords.
