One may wonder why Nintendo would add motorcycles and dirt bikes to the game series that popularized, if not invented, the genre of weapons-based go-kart racing. If you're one of the fans who balked at the inclusion of two-wheeled vehicles, a midair stunt system, and motion controls, rest assured that despite these changes, Mario Kart Wii is still very much the game that you have come to love over the years. But even if you haven't been on the receiving end of a blue shell before, the extensive multiplayer options, deeply integrated online functionality, multitude of controller schemes available, and simple gameplay make this latest Mario Kart great fun and quite possibly the most accessible one ever.
