# Mystery Dungeon (不思議のダンジョン)
**Mystery Dungeon** (不思議のダンジョン, *Fushigi no Dungeon*) is a series of roguelike role-playing video games created by the Japanese developer Chunsoft, in which players explore randomly generated, grid-based dungeons where every step is a turn and death sends the character back to the start. Most entries take their setting and characters from an existing franchise, such as [Dragon Quest](https://www.edgepedia.org/dragon-quest), [Pokémon](https://www.edgepedia.org/pokemon), or the chocobo from [Final Fantasy](https://www.edgepedia.org/final-fantasy), while the Shiren the Wanderer games use original characters.[1](https://dragon-quest.org/wiki/Mystery_Dungeon_%28series%29) • [2](https://strategywiki.org/wiki/Category%3AMystery_Dungeon)

## Origin and first game
The series began with *Torneko no Daibouken: Fushigi no Dungeon*, released for the Super Famicom. It starred Torneko, a shopkeeper character from [Dragon Quest IV](https://www.edgepedia.org/dragon-quest-iv), and was made by Chunsoft, the same developer behind the first five Dragon Quest titles.[2](https://strategywiki.org/wiki/Category%3AMystery_Dungeon) • [1](https://dragon-quest.org/wiki/Mystery_Dungeon_%28series%29) The game translated the conventions of the PC roguelike tradition, in which every step is a turn, dungeons are randomized, and death returns the player to the very beginning, into a console format built around a familiar character. It went untranslated for 33 years despite building a large following in Japan; an English version, *Dragon Quest Heroes: Torneko's Mystery Dungeon Classic HD*, was released at $25 across Switch, Switch 2, PS5, Xbox Series X/S, and PC via Steam.[8](https://www.gamesradar.com/games/roguelike/after-33-years-japans-most-beloved-dragon-quest-spin-off-and-the-progenitor-of-the-entire-roguelike-mystery-dungeon-series-is-out-in-english-for-the-first-time/)
Series director [Koichi Nakamura](https://www.edgepedia.org/koichi-nakamura) explained that using familiar characters was deliberate: because magic and monsters were things players already knew, they could slip into the unfamiliar roguelike system more smoothly, which is why the series initially took the form of Torneko.[9](https://mysterydungeonwiki.com/wiki/Meta%3AShiren_1_DS_Source_Book_Special_Interview%3A_Koichi_Nakamura)
## Shiren the Wanderer
**Shiren the Wanderer** is the series' original-property branch. Chunsoft picked the character out of earlier work to create something newer than Torneko, and unlike Torneko, who simply descends into dungeons, Shiren moves onward through a traveling scenario.[10](https://mysterydungeonwiki.com/wiki/Meta%3AMoonlight_Village_GB_Guide_Book_Development_Staff_Interview) The staff also judged that the portability of the [Game Boy](https://www.edgepedia.org/game-boy) suited the Mystery Dungeon system well.[10](https://mysterydungeonwiki.com/wiki/Meta%3AMoonlight_Village_GB_Guide_Book_Development_Staff_Interview)
Shiren games are harsher than the licensed spin-offs. In Shiren there is no "exit dungeon spell" that returns the player to town, as there is in Torneko; the only outcomes are clearing the dungeon or being defeated, and the basic premise was to make players play repeatedly, growing a little stronger in equipment and items each run.[3](https://www.siliconera.com/chunsoft-chats-about-shiren-the-wanderer/) The series is long-running and rarely localized; the 2024 Switch release *Shiren the Wanderer: The Mystery Dungeon of Serpentcoil Island*, developed and published by [Spike Chunsoft](https://www.edgepedia.org/spike-chunsoft), is a recent mainline entry that reviewers describe as a roguelike with full randomization and high difficulty, softened by quality-of-life features that lower the barrier to entry.[7](https://www.nintendolife.com/reviews/nintendo-switch/shiren-the-wanderer-the-mystery-dungeon-of-serpentcoil-island) • [11](https://www.metacritic.com/game/shiren-the-wanderer-the-mystery-dungeon-of/)
## Licensed crossovers
Most Mystery Dungeon games borrow a setting and characters from another franchise, and several of these crossovers became series of their own.[1](https://dragon-quest.org/wiki/Mystery_Dungeon_%28series%29) • [8](https://www.gamesradar.com/games/roguelike/after-33-years-japans-most-beloved-dragon-quest-spin-off-and-the-progenitor-of-the-entire-roguelike-mystery-dungeon-series-is-out-in-english-for-the-first-time/)
- **Final Fantasy**: *Chocobo no Fushigi na Dungeon*, developed and published by SquareSoft and released in Japan in 1997, followed by later entries including *Final Fantasy Fables: Chocobo's Dungeon* (Wii) and *Chocobo's Mystery Dungeon: Every Buddy!*, a 2019 remaster of the 2007 Wii and DS original for PS4 and Switch.[5](https://gamefaqs.gamespot.com/games/franchise/1510-chocobo) • [12](https://as.com/meristation/2019/03/29/analisis/1553857911_391623.html)
- **Pokémon**: *Pokémon Mystery Dungeon* debuted in 2005 with *Rescue Team* on Nintendo's portable systems, casting the player as a Pokémon rather than a human trainer.[4](https://libres.uncg.edu/ir/uncg/f/Roberts_uncg_0154M_12603.pdf) The 2020 remake *Rescue Team DX* lets players meet and recruit over 400 Pokémon in turn-based battles on changing dungeons.[6](https://www.nintendo.com/us/store/products/pokemon-mystery-dungeon-rescue-team-dx-switch/)
Nakamura said he did not anticipate that, starting with Torneko, almost all major RPG titles, including Pokémon, Chocobo, and Druaga, would go on to develop Mystery Dungeon-style spin-offs.[13](https://mysterydungeonwiki.com/wiki/Meta%3AGAME_SIDE_Interview_with_Koichi_Nakamura)
## Gameplay and design
Mystery Dungeon games are turn-based dungeon crawlers in which movement and combat happen on the dungeon map itself rather than a separate battle screen, so more enemies can arrive while a fight is already underway.[14](https://supremum.gewis.nl/data/supremum_50.2_magazine.pdf) Environments are grid-based, and everything the player uses must be scavenged from monster-filled dungeons.[15](https://www.pcgamer.com/games/roguelike/shiren-the-wanderers-simple-graphics-disguise-a-systems-dense-roguelike-full-of-the-emergent-stories-i-love-the-genre-for/)
Development practice reflects the structure. In recent Mystery Dungeon games there are two separate programs: one for the main storyline with events in between, and another for the special dungeons.[3](https://www.siliconera.com/chunsoft-chats-about-shiren-the-wanderer/) The Shiren DS team also described a Wi-Fi rescue system in which a player who falls in a dungeon can be rescued by another player, with rescuers risking their carried items and the first successful rescuer receiving items from the person rescued.[3](https://www.siliconera.com/chunsoft-chats-about-shiren-the-wanderer/)
## Reception and legacy
The series laid the blueprint for a large family of games and, through the Pokémon and Chocobo lines, spun off entire series of its own.[8](https://www.gamesradar.com/games/roguelike/after-33-years-japans-most-beloved-dragon-quest-spin-off-and-the-progenitor-of-the-entire-roguelike-mystery-dungeon-series-is-out-in-english-for-the-first-time/) Reviewers of the Serpentcoil Island entry place Shiren within the classic roguelike lineage, defined by grid-based environments, scavenged equipment, and punishing difficulty.[15](https://www.pcgamer.com/games/roguelike/shiren-the-wanderers-simple-graphics-disguise-a-systems-dense-roguelike-full-of-the-emergent-stories-i-love-the-genre-for/)
