Super Mario Maker was probably one of the most creative games for the Wii U back in 2015.  Ever since  Super Mario Maker was released for the Wii U and the Nintendo 3DS the game had managed to sell millions worldwide.  Super Mario Maker had managed to sell over 2 million units worldwide for the Nintendo 3DS while doing over 3 million for the Wii U since the Fall of 2015.

Whether or not we see a Super Mario Maker 2 in the future is s bit hard to tell right now especially since Super Mario Maker was released almost two years.  If Nintendo ever decides to make a Super Mario Maker 2 it will probably come in a few years since many people are still enjoying the Super Mario Maker game that was released in 2015.  The idea of having a 3D based Mario Maker title is something that would be interesting since many people are fond of titles such as Super Mario 64, Super Mario Galaxy, Super Mario Sunshine, etc.
