Digital Devil Story: Megami Tensei is the first entry in the Megaten series of games, developed by Namco. It actually takes place after the events of the original Megami Tensei novel.

It is a first-person dungeon crawler in which you can talk to your opponents and convince some of them to join. There is a fusion system that allows the team’s demons to become more powerful, and a lunar phase system that affects demon behavior (and other things, as well).

Since the game doesn’t have a battery back up, passwords must be entered to resume the game after powering it off.
