The “Pre-Mario Maker” Sandbox
Long before Nintendo officially released Super Mario Maker, the homebrew community created Mario Craft DS. Developed by a user simply known as “Nobody,” this project was a hybrid between a level editor and a sandbox game. While it bears the “Craft” name, it is not a 3D Minecraft clone (like DScraft), but rather a 2D construction tool that allows players to draw levels tile-by-tile and play them instantly.
