Mario Kart is a racing game developed by nintendo. You race around a series of tracks in all different types of vehicles. The one thing I would say is that Mario Kart Wii is far better than Mario Kart DS. In Mario Kart Wii the courses are more exciting, the graphics are more realistic and there is a better selection of vehicles. The modes you can play are Grand Prix mode, Time Trial mode, VS mode and Battle mode. I would give it 8 out of ten for wii and 5 out of ten for DS. I would recomend this to Mario fans and racing fans. Being honest, I would say buy it for the wii but not the ds.
