Meta:Mystery Dungeon: Pokémon World: Pikachu's Great Adventure

Mystery Dungeon: Pokémon World: Pikachu's Great Adventure (Japanese: 不思議のダンジョン ポケモンワールドピカチュウの大冒険) is a tentative title for / Pokémon Mystery Dungeon: Red and Blue Rescue Team and may be used to refer to prototype versions of the game.

Official Information

The game began development around November 2003. In a 2012 interview, Shin'ichiro Tomie revealed he initially wrote a completely different story script, before suggesting the idea of a human turned Pokémon, which would later become the story of the released game. No information on the original concept was given.

Leaked Information

The tentative name was first mentioned on August 7, 2004 in the third thread of a Chunsoft general on 2channel, where the economical troubles of the company were being discussed and leaks were being posted. The leaker claimed the game was being developed for the Nintendo DS, the then upcoming handheld hardware from Nintendo.

Observations

While not much about this version of the game is known, a lot can be said about its title. Pikachu being mentioned suggests it might have been the only playable character in the game. This, in combination with its title resembling that of  Torneko's Great Adventure: Mystery Dungeon, may suggest the game was originally planned revolved around a single dungeon specifically designed for Pikachu. "Pokémon World" being a separate title could also suggest the game was being considered as a part of a larger Pokémon series not featuring human characters, including games outside of the Mystery Dungeon franchise, let alone its resemblance to  World of Dragon Warrior: Torneko: The Last Hope's English title. The released game features content and mechanics similar to those seen in  Dragon Quest Characters: Torneko's Great Adventure 2 Advance: Mystery Dungeon and  Dragon Quest Characters: Torneko's Great Adventure 3 Advance: Mystery Dungeon, released in 2002 and 2004 respectively, only in Japan.
