Super Mario 128 is a code name which was reused for two different infamously high-profile development projects at Nintendo in the 1990s and 2000s. Originally intended as a sequel to Super Mario 64, the sequel was canceled and the impetus was reused in a GameCube technology demonstration. As debuted at Nintendo's Space World trade show in 2000, the demonstrated graphics and physics concepts were gradually incorporated into various games through the 2000s. This includes the rapid object generation in Pikmin, the sphere walking technology used in The Legend of Zelda: Twilight Princess and Super Mario Galaxy, and the physics of Metroid Prime.
