The best mario kart by far!
You can unlock a number of characters including rosalina from super mario galaxy. You can also play it online through the wifi connection which i must admit i was very impressed with. The game runs very smoothly online and i have had very few problems with it so far. I would say this game is worth the money just for the multiplayer alone. The game comes bundled with a wii wheel which iv only used once or twice as i prefer the wiimote by itself but its great for kids. The game has 16 new courses along with 16 courses from previous mario kart games. The only thing that disappointed me was the battle mode,i was hoping for more battle games not less but dont let that put you off. Overall i think this is the best wii game out so far!
