Super Mario Maker 2 is a 2019 side-scrolling platform game and level creation system developed and published by Nintendo for the Nintendo Switch. It is the sequel to Super Mario Maker and was released worldwide on June 28, 2019. The gameplay is largely retained from that of its predecessor, in which players create their own custom courses using assets from various games across the Super Mario franchise and share them online. Super Mario Maker 2 introduces new features and course assets, including a single player story mode and new level assets based on Super Mario 3D World. Like its predecessor, the game was met with positive reviews from critics, who praised its user interface, course editing tools, and music, although issues with the online multiplayer mode were criticized. As of December 2022, the game has shipped over 8.42 million copies, making it one of the best-selling games on the Nintendo Switch.
