Its not a bad game, but the game relies to much on the use of the Wii Wheel.
Good: This is a mario kart game and it plays like the other games which automatically makes it a decent game. The Wii Wheel is nice. It feels nicer to use the wheel instead of a controller. It also makes it easier for almost anyone to pick it up and play. The new bikes obviously helped but not to much. There is a lot to do in this game that will keep you busy. There are 8 circuits and 4 difficulties (including mirror) that will give you a lot of one player time. The time trials are trickier this time around. With 10 different vehicles per weight class it gives you many different attempts at the time trials. Not to mention there is multiplayer (which is the best). Now that it is online makes it even better for mario kart fans around the country.
Overall its not a bad game, but I feel it could've been a lot better. It was fun for awhile, but it wasnt one of the games that really impressed me.
