is a series of video games developed and published by Nihon Falcom. The first Dragon Slayer title was an early action role-playing game, released in 1984 for the NEC PC-88 computer system and ported by Square for the MSX. Designed by Yoshio Kiya, the game gave rise to a series of sequels, nearly all of them created by Falcom, with the exception of Faxanadu by Hudson Soft. The Dragon Slayer series was historically significant, both as a founder of the Japanese role-playing game industry, and as the progenitor of the action role-playing game genre.
