is the first game of the popular
Megami Tensei series of
role-playing video games. It is based on the novel
Digital Devil Story by Aya Nishitani. Although
Atlus has published a majority of the series, the first two games were created by
Atlus but published by
Namco (known as
Namcot at the time), after it bought the video game rights to the Japanese horror novel series by Aya Nishitani, the first named
Digital Devil Story. This game is a role-playing video game that features extensive
dungeon crawling and focuses heavily on demons, which have gone on to become a trademark of the series.
