, commonly abbreviated as and marketed overseas as Shin Megami Tensei (originally Revelations), is a Japanese media franchise created by Kouji Okada (credited as Cozy Odaka in English), Ginichiro Suzuki, and Kazunari Suzuki. It is primarily developed by Atlus and currently owned by Sega. The first entry in the series, Digital Devil Story: Megami Tensei, was released in 1987 and its success spawned one sequel, and later multiple subseries that form part of the Megami Tensei franchise. Aside from role-playing games, the series includes examples of multiple genres such as tactical role-playing, action role-playing, and massively multiplayer online role-playing. The first two titles in the series were published by Bandai Namco (then Namco), but have been almost always published by Atlus in Japan and North America since the release of Shin Megami Tensei. For Europe, Atlus publishes the games through third-party companies.
