* BigNameFan:
** HideoKojima is such a huge fan of the entire series that he's put at least two major references to it in his last two ''Franchise/MetalGear'' games: Alta´r's outfit in ''VideoGame/MetalGearSolid4'' and the hay pile in ''VideoGame/MetalGearSolidPeaceWalker''.
** Also, [[spoiler:MGS Raiden is an unlockable costume in ''Brotherhood''.]]
** Also in ''Brotherhood'', when you first meet Leonardo you get a mission to find out where a noise is coming from. After going down some stairs you find a cardboard box in a corner.
* CashCowFranchise: Ubisoft is doing this series every year along with many spinoffs, comic books, and maybe even kids toys.
* FandomNod: ''Brotherhood'' has one early on in regards to being able to relive memories, which was in ''1'', but absent in ''2''. When Desmond is talking to Rebecca about new features, Shaun pipes up with "Is he gonna be able to relive memories this time?"
* FanNickname:
** ''Faffing About Creed'', thanks to [[WebAnimation/ZeroPunctuation Yahtzee]]. Also, ''Ass-Creed'', probably not also courtesy Yahtzee, but his use of it in the review of the sequel has greatly popularized it.
** ''Ass Creed Bro'' or ''[=AssBros=]'' for ''VideoGame/AssassinsCreedBrotherhood''.
** For ''Black Flag'', it's ''Pirate's Creed'' or ''Grand Theft Man O'War''
* HeyItsThatVoice:
** Creator/KristenBell voices Lucy Stillman, Vidic's lab assistant who operates the animus, [[spoiler:and is a member of the same group of assassins that Alta´r was a part of]]. Desmond is voiced by Creator/NolanNorth, who in turn is voiced by Nolan North's dub seiyuu Creator/HirokiTochi.
** And for anime fans, in Japanese dub Alta´r is voiced by Katsuyuki Konishi aka [[TengenToppaGurrenLagann Kamina]] (noticeably audible [[http://www.youtube.com/watch?v=m-K3HMwzYec here]]).
** Desmond and Lucy's Italian actors are respectively [[Manga/{{Naruto}} Sasuke and Tenten]].
** And for any Quebecers (where the game is from), the voice of Garnier de Naplouse (Hubert Fielden) is the French-Canadian dub voice for [[Film/HarryPotter Dumbledore]] PlayingAgainstType (you may have recognized him as the Old Man in ''PrinceOfPersia Warrior Within''). But there is more!
*** Ezio's french canadian voice is [[PiratesOfTheCaribbean Captain Jack Sparrow]].
*** Connor is [[Film/TronLegacy Sam Flynn]].
*** Haytam is dubbed by a [[FamilyGuy certain white dog with a long nose]].
** For anyone (re)playing this game after [[VideoGame/AssassinsCreedII the]] [[VideoGame/AssassinsCreedBrotherhood sequels]], the Rafiq in Damascus and some of the generic citizens have the same voice actor as [[LeonardoDaVinci Leonardo]].
** Arthur Holden ([[WesternAnimation/{{Arthur}} Mr. Ratburn]]) is Sibrand.
** Any British comedy fans playing the first Assassin's Creed might've heard the distinctive voice of [[Series/WhoseLineIsItAnyway Josie Lawrence]].
** The german Connor still defends freedom during WWII as ''Film/CaptainAmericaTheFirstAvenger''.
*** Faulkners german voice actor sadly isn┤t [[CaptainErsatz Joshammee Gibbs]] but [[Franchise/PiratesOfTheCaribbean Davy Jones]].
** Federico Auditore was voiced by [[Series/{{Alphas}} Scipio]] (Elias Toufexis). Meanwhile, Anna (Liane Balaban) voiced Lucrezia Borgia in ''Brotherhood''.
