I said this would be Nintendo's best seller on Wii U for this year and that was back when Zelda was still slated to be released this year.
Mario Maker has huge mass appeal, kinda sucks that it's stuck on Wii U (because it will limit its sales potential), but IMO this was always going to be Nintendo's best selling console game this year.
I don't know why people think 2D Mario is niche and something like console Zelda is massively mainstream. 2D Mario always has outsold Zelda. By a lot.
