Mystery Dungeon is a series of roguelike video games. Most were developed by Chunsoft (later Spike Chunsoft), and select games were developed by other companies with Chunsoft's permission. The series began when co–creator of Dragon Quest, Koichi Nakamura, was inspired by a fellow developer's experience with Rogue and a desire to create an original series. It began on the Super Famicom, progressing to almost all of Nintendo's and Sony's home and handheld consoles, WonderSwan, Dreamcast, Windows, and mobile devices.
