Megami Tensei is a media franchise consisting mainly of role-playing video games primarily developed and published by Atlus. It began in 1986 with the Digital Devil Story novel trilogy, shortly followed in 1987 by a film adaptation and the game Digital Devil Story: Megami Tensei, which had two versions, one by Telenet Japan for home computers and one by Namco for the Famicom, the latter of which has since spawned several spin-offs and sub-series, such as Shin Megami Tensei, Persona and Devil Summoner.
