Start your Mario Karts

Nintendo's famous racing game returns, and with the best-looking graphics the series has ever seen. "Mario Kart 8" features HD graphics running at a crisp 60 frames per second. This is one pretty Wii U game.

As in past entries, players can race using go-karts, motorcycles, four-wheelers and hang gliders. The new addition to the series is gravity-defying upside-down courses: When players reach the antigravity section of a track, their vehicles' wheels turn inward so they can hover. In the background, for example, you'll see waterfalls flowing upward and the Mushroom Kingdom turned on its ear.
