Before the series' creation, the
Mystery Dungeon franchise had only one game known as ''
Torneko's Great Adventure: Mystery Dungeon'' in 1993. It was Chunsoft's first try on bringing the roguelike genre to home console after
Sega's attempt, of which the latter was met with little success.
History The company wanted to work on the new features and gameplay mechanics featured in
NetHack, a variant of
Rogue, with one of them being able to steal items from a shopkeeper. This, however, was not possible to convert the new content from
NetHack with characters from the
Dragon Quest series; one case was with
Torneko, who is himself a merchant in the series. Two years after the release of ''Torneko's Great Adventure
, Mystery Dungeon 2: Shiren the Wanderer'' was released as the company's second work for the
Mystery Dungeon series, with a new world setting and unique characters. Although the first game was not as popular as its predecessor, the company kept working on it later on. Many titles from this series were developed simultaneously throughout the years, where one title was focused on creating original features in its gameplay for home console, while the other was remaining basic, respecting the "traditional dungeon types" for which they were forced to due to the limitations of handheld console:
Mystery Dungeon 2: Shiren the Wanderer on
Super Famicom and
Shiren the Wanderer GB: Monster of Moonlight Village on
Game Boy, and ''Shiren the Wanderer 2: Shiren's Castle and the Oni Invasion
on Nintendo 64 and Shiren the Wanderer GB2: Magic Castle of the Desert
on Game Boy Color. Shiren the Wanderer 4: The Eye of God and the Devil's Navel and Shiren the Wanderer: The Tower of Fortune and the Dice of Fate'' were also developed simultaneously, albeit both of them were released on
Nintendo DS in 2010 and exclusively in Japan. Other contributors outside of the company have participated in the series, such as
Akiman for the Nintendo DS release of the first game, who he himself requested to Nakamura to do some artworks for the characters, of which one of his arts was featured in the Japanese's box art. In 2020,
Shin-ichiro Tomie has left a secret message in the
Nintendo Switch and
Steam ports of
The Tower of Fortune and the Dice of Fate, indicating he is still able to work on the next games if there are enough voices from the fans to green-lit a new
Mystery Dungeon game within the company. This worked as the Switch port of
The Tower of Fortune and the Dice of Fate was well received in reception and sales, thus green-lighting the development of the sixth numbered game,
Shiren the Wanderer: The Mystery Dungeon of Serpentcoil Island. Sugiyama made use of East Asian elements for the series, compared to his more European-styled
Dragon Quest compositions, using instruments such as a
shakuhachi flute. This theme would remain for the series' next titles. Hayato Matsuo later became the main composer for the series, starting in the
Game Boy Color release of
Magic Castle of the Desert in 2001. Sugiyama asked Matsuo not to have his music arranged too much; he had to modify them enough to differ his scores with Sugiyama's for the series. Prior to his death, Sugiyama would occasionally return to contribute only a main theme and some battle themes. After his death in 2021, noisycroak employee Keisuke Ito took the role of main composer for the series. As he previously contributed to the
Pokémon Mystery Dungeon series, his compositions were inspired of the previous composers, while adding his own themes as "a link between the past and the future".
Design New titles are released with unique gameplay for each one, with Seiichiro Nagahata balancing the core games based on how players and employees would complete a dungeon. Shin-ichiro Tomie, the series' scenarist and sometimes director until the spin-off game
Shiren Monsters: Netsal, has suggested to set the series's story in feudal Japan, compared to the previous
Mystery Dungeon title. Character designer
Kaoru Hasegawa later took part during the production of
Mystery Dungeon 2: Shiren the Wanderer after his first contribution in Chunsoft's
Kamaitachi no Yoru (''Banshee's Last Cry
) as an artist. In an interview with the company, they wanted someone who could work on the then sequel to Torneko's Great Adventure'', but he was not familiar with the title, nor the roguelike genre at the time of the interview. After being interested in the genre by playing through the game and being employed in the company, he was able work in the game, with respecting the theme Tomie imposed to the game instead of a western art style, like
Akira Toriyama's
Dragon Quest characters. Many drafts were made for the
silent protagonist of the eponymous game, and its mascot monster the Mamel; most of them were lost. Since then, he has contributed to the series as a character designer, occasionally as an
art director like in ''Shiren's Castle and the Oni Invasion''. From the
Wii release of
Shiren the Wanderer to
The Tower of Fortune and the Dice of Fate, the lead scenarist was replaced by
Masato Kato, as Tomie was working on the other branches of the
Mystery Dungeon series, most notably in the
Pokémon branch, before reprising his role in
The Mystery Dungeon of Serpentcoil Island. == Games ==
