Mario has disappeared! is a 1993 educational game developed and published by The Software Toolworks for MS-DOS, Nintendo Entertainment System and Super Nintendo Entertainment System. A Macintosh version was released in 1994. The player controls Luigi, who must travel the world to find and return stolen treasure as part of a quest to find his brother, Mario, who has been captured by Bowser. Mario Is Missing!, part of a series of educational Mario games, marked Luigi's first starring role in a video game (although he was the main character in the 1990 Game Watch game Luigi's Hammer Toss) , which wouldn't happen again until 2001, when Luigi's Mansion was released on GameCube.
