Pocket Monsters 64 (lost build of unreleased Nintendo 64DD game; 1990s)
Pocket Monsters RPG was an unreleased Nintendo 64DD title. It was meant to be the first console RPG for the Pokémon/Pocket Monsters franchise.
Little info is known about the game and no screenshots have been released. It was first mentioned in a June 1997 interview with Shigeru Miyamoto. Several months later, Miyamoto and Tsunekazu Ishihara both said there were three 64DD titles in development, one of the other two being Hey You, Pikachu!, which would later be released on the Nintendo 64. At Nintendo Space World 1997, only earlier versions of Pokémon Snap and the Japanese version of Pokémon Stadium were shown.
Pocket Monsters RPG fell off the radar and no other info was announced. Junichi Masuda, a major developer for Game Freak, has stated that he doesn't believe Pokémon RPGs should be on home consoles, which could be a possible reason for the cancellation. Other likely reasons are that Game Freak was developing Pokémon Gold and Silver during that period, or that the 64DD ceased production shortly after its introduction.
Two Pokémon console RPGs, Colosseum and XD: Gale of Darkness, were released for the GameCube, but they were not developed by Game Freak, unlike the 64DD game.
