- Acting for Two: Most of the main cast and several supporting cast (Team SHINC) needs to provide two different voices for their character's in-game avatar and their real life self, showcasing the voice artists' vocal range. The only exceptions are Chinatsu Akasaki and Faye Mata who uses the same voice for both Miyu and Fukaziroh.
- Exiled from Continuity: While alluded to a few times, major Sword Art Online characters like Kirito and Sinon are completely absent from the spin-off.
- In fact Episode 2-3 occurs in the background of the Phantom Bullet arc, but the Death Gun incident is never brought up, even though the Bullet of Bullets Tournament is.
- In Episode 9 and 10, Sinon is directly referenced by name. In fact it's revealed she spoke with Team SHINC offscreen at some point before Squad Jam 2.
- The closest we've gotten to a physical appearance is a silhouette of Kirito's GGO avatar in Episode 10 while David is remembering photon swords.
- Fan Nickname:
- PUBG: The Anime, due to its big similarities to that game and the battle royale genre.
- LLENN is often nicknamed "Loli Kirito" due to her taking his place as The Protagonist.
- Fukaziroh is frequently known as "Loli with grenade launcher" or "Explosion Loli" when she's seen by those unfamiliar with the show.
- Team LFnote are better known as "Team Loli", or "Loli Force" to better match the initials.
- I Knew It!: Even those who hadn't read the light novels were guessing Pitohui was Elsa Kanzaki by Episode 6. By the time of Episode 12 it might as well have been a Captain Obvious Reveal with the number of people who had worked it out.
- Amusingly, it's revealed that Karen had started to figure out Pito's real life identity around the time of Episode 6 as well.
- Life Imitates Art: AGGO began publishing as a light novel series in 2014. The anime adaptation began airing in Spring 2018, right when MMO battle royale shooter games like Player Unknowns Battlegrounds and Fortnite were reaching huge popularity.
- Name's the Same:
- No Dub for You: Just like what happened with the Netflix version of SAO (but not with the broadcasted version for TV, as Latin American networks requires any foreign show to be dubbed in Spanish) in Latin America, the Netflix version of the show lacks a Latin American Spanish dub due to Aniplex's restrictions regarding dubbing to any other language other than the original Japanese or English in their licensed shows.
- No Export for You: As of 2018, the light novel, anime and manga are licensed in various regions in English, Latin America, and major European languages. You're out of luck if you live in a country/territory where they don't sell/broadcast either of the three properties.
- Non-Singing Voice: ReoNa provided the singing voice of Elsa Kanzaki, even though her voice actress, Yoko Hikasa, is a singer in real-life.
- The Other Darrin: LLENN was played by Minami Tsuda in Dengeki Bunko Fighting Climax, but was later replaced by Tomori Kusunoki for the subsequent roles.
- Playing Against Type: Allegra Clark as Elsa Kanzaki, an Idol Singer with a squeaky voice.
- Recast as a Regular:
- Aside from LLENN, all of the main quartet are played by voice actors who worked with Sword Art Online in the past.
- In the dub, Anna is voiced by Xanthe Huynh, who previously voiced Sachi in the Aincrad arc.
- Relationship Voice Actor: Pitohui and Fukaziroh have previously worked together on Is It Wrong to Try to Pick Up Girls in a Dungeon? as Freya and Yamato, as well as Trinity Seven as Mira and Ilia.
- Star-Making Role: The role of LLENN for Tomori Kusunoki. Prior to this she was a fairly new and lesser known voice actress, but she became a sensation overnight.
- Also for singer ReoNa, being Elza Kanzaki's singing voice. Over half a dozen insert songs in the show all went towards her big debut in the music industry.
