List of unreleased media

Due to various reasons (ranging from being of poor quality, developing a game for a failed or soon-to-be-discontinued system, or the company facing financial or legal woes), a project can end up being cancelled and cease production. Despite their status, concepts present in cancelled games and other media can be reused in commercial releases, and some cancelled games are repurposed into different projects.

A game in development can also end up becoming vaporware, a term for projects that are announced and for which development is started, but, for similar reasons, were never published.

The following is a list of Mario media that has been cancelled, or was never produced or released.
