The Nintendo Mii craze is still rising, so much so that there will be a new installment of Nintendo Wii commercials starting this week which include the popular Mii characters. The Miis are expected to pop up in ads for Wii Sports and Wii Play. Want to get a sneak preview of these commercials? Go to Nintendo's Wii's MySpace page. For those of you that have not been initiated into the Nintendo Wii world yet, Miis are customizable player characters that you can dress and model after yourself, or your favorite celebrity. They are created with the Wii console, or if you don't have a Wii, you can make one online, take a screen shot of it and save it in the Mii group. So how do you join the geeksugar Mii Challenge?
