Chocobo de Battle (cancelled Final Fantasy spin-off fighting game; 1997)
Chocobo de Battle would have been a Final Fantasy fighting game spin-off where the playable characters were Chocobos. It was first announced in 1997 in an issue of the Japanese magazine Famitsu and had a tech demo featured at Siggraph 1997. It was planned for release in arcades (with a possible PlayStation port) and had it been released, it would have been Square's first arcade game, but it was cancelled for unknown reasons.
From what little footage is available of the game, players would control a Chocobo that had the ability to fire missiles. To control the Chocobo, rather than using conventional arcade controls, the player would hover their hand over a blue motion-sensing pad with which they'd have to perform various hand gestures to attack, move, and perform combos.
While the game was cancelled, the tech demo at Siggraph proves that there was, at some point at least, some kind of prototype for the game. The prototype hasn't surfaced online or been shown off anywhere since, but either Square or someone who worked on the game may have a copy of it.
