This game is perfect for kids who are just entering the world of video games.
The two player mode is exceptionally fun. It serves as an excellent introduction to games of its type. The little cars are varied and interesting, the venues are large and differ enough to keep things entertaining. As the game is, exclusively, centered around driving and collecting items, there is no violence - another attractive feature for parents concerned about what their kids are learning from their games. I love GTA IV, but not for my 5 year old.
My kids and I have wiled away many hours, competing against ourselves and each other. If you find this one in your local bargain bin - especially if you have young children who are just starting to game - you should grab it.
