Granted, this game is not for me. I'm a dad, I rented it for my kid who loves Cars, but it was a little clunky. Graphics seem rushed, very quickly done, and the game play seemed to just lack anything fun.
I played it for 5 minutes and handed the controller to my kid, he didn't like it either. Neither one of us wanted to spend the time to "unlock" stuff either. Note to developers: stop with the unlockable content, or at least give me a code to bypass it. Trying to explain to my kid that he has to beat the beginning levels to unlock those cool looking 'locked' tracks never goes over well.
