Most of the titles were developed by Chunsoft, but other titles were developed by different companies with permission from Chunsoft to use the trademark.  Koichi Nakamura, founder of Chunsoft and co-creator of the "Dragon Quest" series, conceived the "Mystery Dungeon" series as Chunsoft's first original work, basing the design on the game "Rogue".  Most "Mystery Dungeon" games center on exploring a dungeon with randomly generated layouts and fighting other characters in those dungeons in a turn-based manner; every time the player performs an action, such as attacking or walking, the opponents also take action.  The first title, "" (1993), starred Torneko, a shopkeeper character from Chunsoft's "".  The games of the "Mystery Dungeon" series can be largely divided into five groups: those related to the "Dragon Quest" series; the "Shiren the Wanderer" series; those related to the "Chocobo" series, itself a spinoff of the "Final Fantasy" series; those related to the "Pokémon" franchise; and individual spin-off games of other franchises.  Of the games, only the "Shiren" series are based on original characters rather than those of other franchises.  The "Mystery Dungeon" games have had varying levels of success.  Of them, the "Pokémon" games have had the biggest impact, with the first game in the subseries selling millions of copies.  "Chocobo's Mysterious Dungeon" also sold over one million copies.
