The graphics are INSANE!! I mean, it is a mobile game so I think they are good. But i hate to say, but the physics are not the best, I personally have seen better. I think the game good do with some more cars, there are not so many. (The cars that are in the game are modeled good) (Cough cough, i love if the rx-7 good come in the game) So I personally think it is only a 3 star, bc it is only the physics that are not so good, and there are not so many cars. !!! I am typing this on the date that it says, there could have been a update end between when you see this !!!
