Super Mario Maker is a game published by Nintendo in September 2015. It is the first Mario platformer game from Nintendo with a true level editor (unless you count "Coin Edit Mode" in New Super Mario Bros. U). Visually and stylistically, it is based on Super Mario Bros. for the NES, Super Mario Bros. 3 for the NES, Super Mario World for the SNES, and New Super Mario Bros. U for the Wii U. From a technical standpoint, it is based on an early version of Splatoon, which is itself based on Super Mario 3D World. For that reason, many of the files and techniques in this game more closely match those games than New Super Mario Bros. U.
