"Mario Is Missing" is a well-known educational Mario fan game that was developed and released in the late 1990s. Unlike most Mario games that focus on platforming and action, "Mario Is Missing" is an educational game designed to teach geography. The game stars Mario, Luigi, and Princess Peach as they travel around the world.
This initial version of Mario is Missing was notable for its technical prowess within the Flash medium, featuring a dress-up system and intricate H-event chains for enemies. Its popularity quickly grew, but Playshapes disappeared from the internet in 2012, leaving the project unfinished.
"Inspired by 'Mario Is Missing: Peach's Untold Tale 3', I'd love to hear your ideas for alternative Mario storylines. What if Peach had her own adventure? How would it intersect with the main Mario games?"
