I for one do not allow my kids to use Game Cheat Codes. Now maybe I am an awful parent because "everyone" does it and "it is just a video game" but I believe that they need to earn the points to buy the car they need to win the race. I believe that they need to be able to work their way to the next level without the help of a cheat code. I believe that the world is not going to end because they have to work at winning the game instead of punching in a code.
