Super Mario Maker 2

Like its predecessor, Super Mario Maker 2 is a side-scrolling platform game in which players create their own courses using assets from across the Super Mario series and publish them onto the internet for others to play. Players can choose from a selection of prior Super Mario games to base their courses' visual style and gameplay on, including Super Mario Bros., Super Mario Bros. 3, Super Mario World, New Super Mario Bros. U, and the newly introduced Super Mario 3D World theme, which has been retooled to 2.5D to fit with the game's platforming style. Gameplay mechanics and enemy behaviors can vary between the styles, with some elements being limited to specific styles.

The sequel adds various assets and tools, including assets and a course theme based on Super Mario 3D World. This theme is especially different from the four others, with many features and gameplay mechanics unique to it. Due to the difference from this style to the others, it is labeled as an "extra" game style and the course has to be reset in order to switch to this style. This sequel also brings along the new vertical course feature giving creators the ability to raise the vertical height limit. It also introduces local and online multiplayer modes including co-op course creation, where up to two players can locally create stages together at the same time; as well as allowing up to four online players to complete user-made courses, cooperatively or competitively.

Developed inhouse at Nintendo's Kyoto Development Center, planning for Super Mario Maker 2 began alongside development of the Nintendo Switch hardware itself. Most of the original development team reprised their roles for this sequel, including producer Hiroyuki Kimura, director Yosuke Oshino, and planner/game designer Shigefumi Hino. Nintendo's producer Takashi Tezuka stated that the theme for the sequel was to expand on what could be done compared to its predecessor and try new things, which took the form of new course elements and new side content in the form of a full-fledged single player campaign. Tezuka also stated that as players continue to upload levels, he and the development staff would use these creations as a reference for adding content after launch, viewing the dynamic as a give-and-take between developers and consumers.

Longtime Super Mario series composer Koji Kondo served as the game's sound director and composed some music. Additional music was composed by Atsuko Asahi, Toru Minegishi, and Sayako Doi.

Super Mario Maker 2 received "generally favorable" reviews, according to review aggregator website Metacritic. Fellow review aggregator OpenCritic assessed that the game received "mighty" approval, being recommended by 95% of critics. The online multiplayer feature, however, was criticised for its performance issues. GameSpot, who gave the game an 8/10, stated that online lag frequently ruined the experience.

It was the best-selling game in Japan during its first two weeks of release, selling 279,357 physical copies. By the end of March 2021, the game had sold over 7.15 million copies worldwide, making it one of the best-selling games on the Switch. The 2023 CESA Games White Papers revealed that Super Mario Maker 2 had sold 8.42 million units as of December 31, 2022.
