One thing that annoyed me was all of the green and red and yellow lights I collected did not save, and I had to get them again. The coins saved however. I dont know if this is intentional or not by the game designers. However, the positives far outweigh that one complaint: +Runs lag free on my new mac +Pricetag is great +Lots of really cool looking nitro cars +Huge maps +Absorbing Free Play +Multiple Game Types (unlocked when you find the coin in freeplay, there is also a cheat to help you find coins, press "c" for an arrow to point to it) +Good graphics +Tons of powerups A very enjoyable game. The value of this is up there with xbox games for entertainment, the price is a steal! Youd be a sucker to miss out on this.
