* 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.
* 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.
** And "Ass Creed Bro" for ''VideoGame/AssassinsCreedBrotherhood''.
*** Or [=AssBros=]
*** 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]].
