Megami Tensei is a Japanese role-playing video game metaseries which was originally based on the novel series Digital Devil Story by Aya Nishitani (taking its name from the title of the first of those novels) and has gone to become one of the major franchises of the genre in its native country. The games are published by Atlus with the exception of the Famicom games, which were published by Namco. Although most games in the series have independent stories, the Megami Tensei series has many common elements. Demons and mythology are prominent in each installment, usually giving players a chance to recruit demons into the battle party. Other common elements include certain game mechanics and plot themes. Most games in the series feature nonlinear gameplay offering freedom of choice between branching paths and multiple endings, a conversation system allowing players to engage enemies in conversation, the ability to use or capture monsters, and a moral alignment system.
