Mario Kart Wii will include 16 new courses and 16 classic courses from previous Mario Kart games. For the first time ever, players have the option of racing with either karts or motorbikes. Players can also hit the road as their personalized Mii caricatures in addition to the handful of classic Nintendo characters found in the game. True to the series, the game features tons of racing, plenty of power-ups and oodles of objects for players to use to slow down other drivers. And 10 battle arenas will keep players busy between trips around the circuit.
