The Legend of Zelda: Space World 2000 Demo was a technical demo shown at Space World, a game trade show hosted by Nintendo in 2000. The demo was part of a tech demo showcasing upcoming games for the Nintendo GameCube. Fourteen seconds of the video depicts Link in a sword fight with Ganondorf. Both of the characters' models were based off their designs in The Legend of Zelda: Ocarina of Time, but rendered with the graphics capabilities of the GameCube. It was directed by Yoshiaki Koizumi, who also designed the character models for Link and Ganondorf that are used in the demo.
The demo was designed as only a technical demonstration and was never intended to be an actual game. Despite this, both fans of the series and the media speculated that the battle might be from a game under development or at least an indication of the direction the next The Legend of Zelda game would take. This would later come to the surprise and subsequent discontent from fans when Nintendo announced The Legend of Zelda: The Wind Waker, featuring a cel-shaded art style and a younger Link. A later game in the series, The Legend of Zelda: Twilight Princess, would be closer to the Space World 2000 demo in its graphical style.
Interestingly, an image of Link from the demo was used to promote the release of The Legend of Zelda: Ocarina of Time Master Quest. Additionally, the character design used for Ganondorf, as well as his sword, is re-used for his trophy and playable appearance in Super Smash Bros. Melee.
