Mystery Dungeon is a series of roguelike video games, most of which were developed by Chunsoft, but with select titles in the series developed by other companies with permission from Chunsoft to use the name. Although all games in the series bear the Fushigi no Dungeon moniker somewhere in their Japanese titles, only the Shiren the Wanderer games contain original characters; all other license their characters from other role-playing game franchises. The first title, Torneko no DaibÅken: Fushigi no Dungeon starred Torneko, a shopkeeper character from the same developer's Dragon Quest IV (Chunsoft being developer of the first five games). Mystery Dungeon games are notable for being among the few console games in the roguelike genre. The series has inspired similar titles in Japan, most of which appropriate their games mechanics from Mystery Dungeon, rather than Rogue itself.Most Mystery Dungeon games centre around exploring a dungeon with randomly generated layouts and fighting other characters therein in a turn-based manner; every time the player performs an action such as attacking or walking, the opponents also take action. Escape from the dungeon is usually only allowed in certain places, or through the use of certain items. Additionally, when the player loses the game the player loses all money plus half the player's items in the more forgiving variants, or loses everything and has to start from scratch in others.The series features an original cast on occasion, which has as its hero Shiren the Wanderer, who journeys with a talking weasel named Koppa, and during their adventures they meet many characters such as Shiren's brother Pekeji, and Orya, a female character that blinds every man she meets
