It just keeps getting better and better!
-The A.I., make the CPUs smarter, like if I were to hit an opponent, he would actually try to take revenge on me.
-The difficulty, make it a little less difficult, this game is actually pretty hard, in the exception of free play, where you can set the level of difficulty.
-The physics, make the cars show damage when hit like broken hood, bumber, windows, etc.
Overall this is a great game, I would recommend buying it.
