Super Mario 128

Super Mario 128 was a GameCube tech demo shown at the Nintendo Space World trade show in 2000. It's simply 128 Marios trying to push each other off to their deaths. Despite never being released to the public, the technology/code of the demo would later appear in the Pikmin games, Super Mario Galaxy and other JSYSTEM games.

The director of Super Mario 128, Yoshiaki Koizumi, would go on to serve as the director of Super Mario Galaxy.

Several YouTube videos with footage of the live demo from people who attended Spaceworld 2000 are available. Some, but not all included:
