The game was great fun while it lasted. The problem was that on chapter 4, the game always gave error 151. After googling it, it's an issue with buggy copies, and even brand new copies of any game can have it. Have to warn all other customers:Gamefly has at least one broken copy.
The open world is pretty massive. a decent selection of cars, fun missions and some genuinely funny moments. this game was a blast to play, plus all of the hidden Nintendo easter eggs to try and find. this game will take up hours upon hours.
