I have been saying it from the first time I saw the Wii U, the next "Wii Fit" game could be a learn-to-draw game (like Art Academy DS but way better) on the Wii U ...

As a rough guestimate, at least 25% of people would like to be more artistic and there is about 1 person in every household who would want to learn to draw/paint. A well made art game could easily sell 20+ Million units worldwide.
