- Newbie Boom: While Atlus had attempted to bring over Shin Megami Tensei games to the west before, including the infamously bad port of the first Persona and skipping Innocent Sin in favor of Eternal Punishment, confusing a lot of people in the process, This game in particular was popular enough to start getting the trend of Truer to text Shin Megami Tensei titles being brought to the west, culminating in the breakout popularity of Persona 3 onwards later down the line.
- No Export for You: Of the three editions of the game, only Maniax made the cut outside of Japan.
- Sequel First: This was the first mainline SMT game to be released outside of Japan. And even then, it was the Updated Re-release that made the export, rather than the vanilla edition.
- Sequel Gap: Released nine years after Shin Megami Tensei II in 1994. And that's if you live in Japan.
- Word of Dante: While there is no official word on who Jyoji really is and what sin he committed, it has been accepted in pretty much the entire fandom that he is Aleph.
- Working Title: The game was known as Shin Megami Tensei: Vortex during development.
