Which company co-developed Super Mario RPG with Nintendo? Square. The 1996 role-playing game was developed by Square and published by Nintendo for the Super Nintendo Entertainment System.
The project began after a 1994 meeting between Nintendo and Square. Nintendo wanted to bring Mario into an RPG, while Square wanted to create a role-playing game with broader international appeal. Shigeru Miyamoto produced the project, and Square supplied much of the RPG design and development expertise.
Super Mario RPG combined turn-based battles inspired by Square’s Final Fantasy games with platforming, jumping, humor, and an isometric 3D world modeled around Mario’s style. It introduced characters such as Mallow and Geno and became the foundation for later Mario RPG series, including Paper Mario and Mario & Luigi.
A common mix-up is answering Nintendo because Nintendo published the game and owned Mario. Square was the development partner; after corporate changes, the company became Square Enix. A Nintendo Switch remake was released in 2023.
