Nintendo has started the first Mario Kart Wii competition, which you can start playing right this second.
To enter, simply go to the Mario Kart channel and scroll down to the Competitions option. Providing you've downloaded the latest data (the bottom option), you'll get the following message, "Get the best time you can in a VS on Mario Circuit."
That means computer characters are on the course and normal items are in use. The course has been changed slightly, with items placed differently and the chain chomp is prowling around, freely.
We're not entirely convinced about the challenge, given the randomness eleven computer characters bring to the course. Never-the-less, we'll be competing. The competition will run until May 10. Go!
