- Cowboy BeBop at His Computer: The game has attracted haters for having the option of a playable female protagonist. Reactionary Youtubers are accusing the game of revising history for the sake of inclusion, somehow missing that the game also includes boss fights with mythological creatures, a magical spear that grants invisibility and powers of the elements, and the highly fictional war between Assassins and Templars. The same element also drew criticism for apparently "double dipping" the possibility of having a playable female character after Syndicate did the same thing, apparently forgetting that Evie was more And Now for Someone Completely Different while Kassandra is a proper, full-on protagonist.
- Follow the Leader: Several game mechanics - generation of endless random mercenaries, ability to recruit your opponents, occasional fight over the region, ability to "teleport" from opponent to opponent and and an attack that fills your special move meter - are almost direct lifts from Monolith Games' 2017 game Middle-earth: Shadow of War. As Assassin's Creed: Syndicate borrowed from series' first game Middle-earth: Shadow of Mordornote , Ubisoft seems to be a fan.
- The ability to recruit pretty much any common mook in the game by taking them down non-lethally to work for you was also a notable mechanic in Metal Gear Solid V: The Phantom Pain (and Metal Gear Solid: Peace Walker before that). The fact that the main characters of both Odyssey and MGSV are famous mercenaries who seemingly can recruit on reputation alone only reinforces the similarities.
- Relationship Voice Actor: Just like previous AC games, many members of the Japanese dub of the game worked previously in the Gundam franchise previously: So far, we have Risa Shimizu (Arlette Almage) as Kassandra, Kikuko Inoue (Aina Sahalin, Carta Issue and Caridad Yamato) as Myrrine, Hideyuki Tanaka (Woody) as Herodotos, Fumihiko Tachiki (Muron Muron) as Sokrates, Joji Nakata (Federico Czariano and Edmond Du Clos) as Leonidas, and Bin Shimada (Paptimus Scirocco) as Kleon.
- Role Reprisal: In a surprising reprisal in the Japanese dub, Joji Nakata, who voices Leonidas, already voiced that same historical character in the dub of 300, a fact he personally lampshades in his Twitter account.
- What Could Have Been: The game was originally intended to be a Rogue One-style spin-off titled Odyssey: An Assassins Creed Adventure before being made into a main installment.
