Nintendo has confirmed that Super Mario Maker is making the jump from Wii U to 3DS.
This portable version is focused on creating local connections rather than sharing online, with StreetPass being used to exchange courses with close friends. It will include access to some Wii U courses to play, but not every level from the home console version will be compatible.
It's very much being pitched as the local sharing equivalent to the online-centric Wii U version; there'll be no online uploads for courses created in this 3DS iteration. Some Wii U content won't be making the transition, such as the Mystery Mushroom and related outfits.
It's coming on December 2nd 2016.
