- Digital Devil Story was not the only novel by Nishitani that inspired a game. His later released Tokyo Shadow novels were made into a game for the Sega Saturn and Playstation.
- According to Nishitani, the idea for the demon summoning program came from his interest in astrology as a child which lead to him learning about western black magic. Because of this he thought the idea of practicing black magic on a PC would be interesting.
- He was inspired by Hanmura Ryou and H.P.Lovecraft.
- In 1994 his favourite game from the series was Shin Megami Tensei.
- He has said that at the time of writing the original books that the Chaos alignment was closer to his way of thinking but now he currently prefers the Law alignment.
