As I argued before, I think it's still likely that Nintendo will profit from the intellectual labor players invest in Maker, and that we'll see the fruits of the community's work in the next Mario game. That said, Nintendo isn't Facebook. Maybe it's better to think about it in terms of participation and collaboration than the work of the many in thrall to the few.
The defining characteristic of Yoshi's Woolly World—teed off by that alliteration in the title—is its aesthetic: yarn and glue. That woolliness bridges the gap between stereotyped gifts from grandma and the twee squeak most every Etsy storefront seems to be trying to wring out of you. This game is bright, soft, fuzzy, and unabashedly so.
