Kyouryuu Ouji Don (cancelled Super Famicom RPG game; 1994)
Kyouryuu Ouji Don ("Dinosaur Prince Don"), also known as just Don, is a cancelled 1994 Super Famicom RPG action side-scrolling game that was being developed by Taito. It would have starred a triceratops named Don who must solve various problems that plague his home and people living in it.
Before getting its name, Taito ran a contest in Japan to name the character and game. It was meant to be released in Japan first and possibly the US later, but the game was ultimately cancelled for unknown reasons.
No prototypes or other information of the game has surfaced aside from some magazine articles.
