Super Mario 128 (lost build of cancelled GameCube/Wii game; 2000-2006)
Super Mario 128 was a tech demo first shown at SpaceWorld 2000 and a potential game for the Nintendo GameCube/Wii.
The name Super Mario 128 first came up in an issue of Nintendo Power from 1997. It said the name Super Mario 128 was a possible name for a Super Mario 64 sequel.
The tech demo featured 128 Marios in the game. The Marios could manipulate the terrain by bringing the structure up and down, and they could also change the board to a pizza. The tech demo was intended to test the large amounts of bots that the GameCube could handle, a deed that was nearly impossible for the Nintendo 64.
In 2005 Reggie Fils-Aime said that Super Mario 128 would make an appearance at E3, but it did not. That same year, Miyamoto gave some information on the game; he said that Mario would be in a game with a new character by his side and that it would not be on the GameCube but on the Wii.
In 2006, Miyamoto confirmed that Super Mario 128 was cancelled, but many elements of the demo were used in Metroid Prime, Super Mario Galaxy, and The Legend of Zelda: Twilight Princess. In 2007, Miyamoto said after his keynote speech that Super Mario 128 was turned into the Pikmin games.
Though it's unknown if Super Mario 128 was actually fully developed as a game, the original tech demo hasn't resurfaced or has been leaked to the internet and all that remains of the tech demo are video recordings and screenshots of the demo at SpaceWorld 2000.
