The maker of the next Super Mario Bros. game is … you.

During Nintendo’s digital event today during the Electronic Entertainment Expo in Los Angeles, Nintendo announced a new Super Mario Bros. map editing game — Mario Maker. 3DS players will be able to use assets from various Super Mario Bros. series titles, such as the classic pixelated bricks and pipes from the original NES classic to more updated looking items from New Super Mario Bros., to create their own levels.

Nintendo is looking to release Mario Maker some time in 2015.
