As a racing game, Cars isn't bad, but its real strength is in its presentation. It's not quite as sharp as the film, but the cars are expressive and well-animated to the point where their chrome lips actually sync up well with the dialogue. (They also like to mug at the camera a lot during the cinemas.) Also, in what might be a first for a licensed game, all of the film's A-list actors - from Owen Wilson to John Ratzenberger - recorded original dialogue for the game. It's pretty cool, although we could have done without hearing Wilson say "Ka-chow!" every five minutes.
The console versions of Cars are all essentially identical, although the 360 edition does pack in sharper, hi-def visuals and some new bonus content, including a so-so minigame where you chase Mater around with a lantern.
