The reason for the ten-year gap between III and IV was that the company had made other successful titles, and had not had the time to develop Shin Megami Tensei IV as well.
Der Grund für die zehnjährige Pause zwischen „III“ und „IV“ war, dass die Firma andere erfolgreiche Titel produzierte und deshalb keine Zeit hatte, um nebenbei „Shin Megami Tensei IV“ zu entwickeln.
