"The talented team initially wanted to make a revamped Mario Paint title for the Wii U that fully utilised the Wii U GamePad, but at the same time they also wanted to use the Super Mario Bros toolset."

         "Originally we wanted to make a Mario Paint game, using the Wii U GamePad,” says Tezuka. “And that was where the idea originally started, but at the same time, we wanted to take the Super Mario Bros. toolset that we use to create the levels, and we wanted to move that toolset over to the Wii U GamePad to make it easier to create the levels with the touchscreen.”

          I always had the feeling that SMM started out as a Mario Paint game to be honest. I would have loved another Mario Paint game, but I'm happy enough that we got SMM instead!

I wish it was a MP game. I don't care for Mario Maker.

Just like Splatoon was going to be a Mario game too.
