* ActorSharedBackground: Just like his character Connor, Noah Watts has Native American ancestry (in this case, Blackfoot).
* BeamMeUpScotty: [[PlayingWithATrope Played with]] when you ride with Paul Revere. Contrary to popular belief, Revere never shouted "The British are coming!" on his Midnight Ride, and the game never depicts him saying it... but one of the first people you alert ends up shouting it to the people in his house after you and Revere pass on the message.
* TheDanza: Kaniehtí:io, as portrayed by Kaniehtiio Horn.
* FakeAmerican: UsefulNotes/GeorgeWashington is voiced by the British Creator/RobinAtkinDownes with an American accent.
* FakeBrit: Canadian actor Adrian Hough portrays Haytham Kenway, a British Templar.
* FakeNationality:
** Subverted. Noah Watts is Native American just like his character Connor though he is actually Blackfoot instead of Mohawk (see ActorSharedBackground above).
** The Mohawk Kaniehtí:io is played by Creator/KaniehtiioHorn who is from a Canadian Mohawk First Nations tribe.
* FollowTheLeader: The re-worked combat mechanics owe a lot to the "free flow" combat style popularized by big hits at the time such as the ''VideoGame/BatmanArkhamSeries''.
* InspirationForTheWork: As [[https://twitter.com/GameAnim/status/1258056884088520705 tweeted by Jonathan Cooper]] (a former Ubisoft animator) on 2020, the [[https://www.youtube.com/watch?v=nHbRCd8yzaw pre-rendered gameplay pitch video]] for the [[{{Vaporware}} cancelled]] ''Franchise/PrinceOfPersia: Redemption'' game served as an inspiration for their pitch on ''Assassin's Creed III''.
* TechnicalAdvisor: Because the game features Connor, a half-British, half-Mohawk Assassin, Creator/{{Ubisoft}} hired Thomas Deer from the Kanien’kehá:ka Onkwawén:na Raotitióhkwa Language and Cultural Center to basically keep them in line. He advised them on what was and what was not appropriate to depict, as well as coached voice actor Noah Watts in the Mohawk language.
* TrailersAlwaysLie: A portion of Charles Lee's [[BreakThemByTalking breaking speech]] ("Even those men you sought to save have turned their backs on you, yet you fight. You resist. Why?") was attributed to ''Achilles'' in the ''Connor Story'' trailer to emphasize the tension between him and Connor. While they do have several arguments in the final game, their relationship is far more amicable than the trailer suggests.
* WhatCouldHaveBeen:
** Aveline was considered to appear in the ''Tyranny of King Washington'' content, with the developers contemplating to [[PromotedToLoveInterest make her a love interest]] for Connor.
** Canoes were seen in early screenshots, presumably meant to work like the gondolas in ''ACII''.
** The devs played with the idea of letting players scalp their enemies, but realized that Mohawks didn't do so.
** Judging by his character artwork (which can be found on his [[https://assassinscreed.fandom.com/wiki/Charles_Lee wikia page]]) Charles Lee was originally meant to own a small dog, likely as a nod to the real one's fondness for them. Even as the man himself went through various designs, the little fuzzball persisted but ultimately didn't make it to the actual game.
