- Actor Allusion: Strassman is voicing yet another blond gunwielder in an Atlus series.
- I Knew It!: Well before release, fans guessed that YHVH would return and sure enough.
- Some players of the previous game suspected that Nanashi would be the reincarnation of Akira in the present.
- Lying Creator: Minor case, promotional material stated that there would be 450+ demons in the game. The actual count is around 420.
- Marth Debuted in "Smash Bros.": DLC marks the international debut of Aleph, protagonist of II, as his game never got released outside of Japan. Barely averted with the Hero and En no Ozuno, as I was released on Apple products internationally a few years prior to Apocalypse.
- Name's the Same:
- Asahi: Your childhood friend, or a beer brand?
- No one steals Press Turns like Gaston!
- No Export for You:
- Averted since publisher Deep Silver will bring this game to PAL territories.
- And averted once again for the regions forgotten since the previous game, like most of Central and South America, who couldn't even acquire the DLC due to region barriers, much less purchase the game digitally.
- Relationship Voice Actor: Nanashi and Krishna are once again opposing each other, but this time not in a courtroom. Also, Toki is Watson's daughter.
- The Other Darrin: Karen Strassman took over for Laura Bailey as Nozomi and Sean Chiplock from Liam O'Brien as Navarre.
- What Could Have Been:
- The game started as an Updated Re-release of Shin Megami Tensei IV, until the production staff realized they had so much new content and so many new ideas they needed an entirely new game to fit them all.
- While SMTIV was released with a two-month export turnaround between Japan and North America, with Europe getting it much later, SMTIVA has the opposite problem, with North America getting it seven months after Japan, but PAL regions only needing to wait two months after North America.
