You may want to think twice before sharing your physical copy of Super Mario Maker for Nintendo 3DS. If the game is inserted into someone else’s 3DS, your save data will need to be wiped off in order for it to be played on that system. This is because of how the hand-held version of Super Mario Maker works. When you begin using the game, new save data is created on both the game card and SD card; you need both files to continue playing. If someone else uses the same game card and wants to play on a different 3DS, the save data on it must be completely deleted before a new one can be created.
