Super Mario Maker is possibly the big sleeper of 2015

[PAOerfulone]

It's looking already like it has the quality to be a GOTY candidate, now all it needs is the Splatoon/Mario Kart/Smash Bros. level of marketing behind it, release it in the holiday season this year and it'll do HUGE numbers!
Bundle it with the Wii U, and this could very easily be the Wii U's best holiday season.
Nintendo, don't screw this up!
