In honor of the release of Wii Party next month, Nintendo is holding a special contest. Players who participate and are chosen will have star in a TV ad for Wii Party. The entry form asks players questions about their ideal party, which includes why Nintendo should promote it, who would they invite and even their favorite food.
The contest starts on September 3 and will end on September 10. The contest is open for players within the United States.
