Stage Debut is a cancelled game for Nintendo GameCube.
Summary
The game was a planned spiritual successor to Mario Artist: Talent Studio, with cameos of Mario, Animal Crossing, and Pikmin. It would have allowed the player to use a camera to import photographs of faces into the game, and interact with characters using the faces in special ways, such as on a stage.
It would have also supported the e-Reader and Game Boy Advance. Although the game was never released, according to Shigeru Miyamoto elements from the game are used by Miis and the Mii Channel.[1]
