If you are a fan of Mario Kart and if you like Disney characters, then you'll love this game.
As the name of the game states, the courses are based on places in the USA. The courses are well detailed and they increase in difficulty as the game goes on. There are 5 circuits in the game with 4 races in each. Courses range from Los Angeles to Texas.
Overall, this is an excellent racing game to be played with other people. In fact, this is a perfect family game. Since I've seen so many similarities with other racing games, it is easily comparable to Mario Kart with both its strengths and weaknesses. If you have no other racing game out there that you could play, then this game is worth playing.
