We might see more than just the original Mario Bros. and NSMB skins in the final version of the game.
Art assets from other Super Mario Bros. games, such as Super Mario Bros. USA, Super Mario 3, and Super Mario World are being considered to be implemented into Mario Maker, Takashi Tezuka revealed to us in an interview. While Tezuka could make no promises, he went on to say that the development team is considering the use of different skins in the the game but currently are not sure which ones they are going to use in the final version.
Mario Maker will release on the Wii U in 2015. For more information on the game, be sure to read our hands-on preview here and check out the video of the game form the E3 show floor below.
