Well spoken. Definitely agree with what Tony and Dignan said. We just got my nephews (ages 5 and 7) a Gamecube. I thought they were still a bit too young to get a system but its worked out great. I'd start them off with some buttom mashing type of game where they can just get used to the whole hand eye coordination thing. Teenage Mutant Ninja Turtles turned out to be a great choice and there's a good chance you can find it used for cheap. Then definitely on to Mario Kart.
