History Trivia / KingdomHearts3DDreamDropDistance

** Hayden Panettiere has replaced Alyson Stoner as Xion. This one is interesting--obviously the intention is for Kairi and Xion to have the same voice actor, but Panettiere was unavailable for Xion's debut, meaning Stoner is her original actor.

* IKnewIt:
** Who ''hasn't'' suspected [[WesternAnimation/TheHunchbackOfNotreDameDisney Notre Dame]] or [[VideoGame/TheWorldEndsWithYou Neku Sakuraba]] showing up sooner or later?
** The idea that the game is taking place in a dream, with new, dream-based enemies.
** When the ''WesternAnimation/{{Fantasia}}'' world was confirmed, people suspected that [[BestBossEver Chernabog]] would be making an appearance. And they were right.
** Fans knew a world for ''Film/TronLegacy'' was coming due to the popularity of the Space Paranoids level as well as [[GermansLoveDavidHasselhoff the movie's popularity in Japan.]]
** The "symbolicness" of the cover, [[spoiler: a lot of fans expected Riku to be the true hero of the story.]]
** We also knew that ''WesternAnimation/{{Pinocchio}}'' would get a world sooner or later. Heck, we knew it in ''[[WhatCouldHaveBeen 358/2 Days]]''.
** Some fans have always insisted that [[spoiler: Nobodies do actually have hearts]], despite the games claiming the exact opposite. In this game, Xemnas [[spoiler: explains that they're half right. Nobodies are indeed created with no hearts, but develop replacements for their hearts over time]].
** Some fans have speculated that the depths of Sora's heart looks like the Destiny Islands. They were right, as when [[spoiler: Riku dives into Sora's heart to wake him up, he finds Xion, Roxas, and Ventus on a perfect replica of the island Sora, Riku, and Kairi visited when they were younger.]]

* TalkingToHimself: Sora and [[spoiler:Vanitas]] have a cutscene together, sort of.

** This is also the last time Creator/RussiTaylor voiced Minnie Mouse in the series before her death in 2019; as well as Creator/PatCarroll as Ursula before her death in 2022.

* ColbertBump: This game gave substantial exposure to ''VideoGame/TheWorldEndsWithYou'', which, while successful, was previously considered a dark horse among Square Enix [=RPGs=] and more akin to a CultClassic.

* RecycledScript: Pretty much ''VideoGame/KingdomHeartsChainOfMemories'' only with dreams instead of memories. Sora and Riku are once again [[BagOfSpilling de-leveled]], separated and trapped inside a ClosedCircle, visit worlds that are not real (dream worlds instead of memory worlds this time around), are regularly antagonized by Organization members that drop cryptic hints, Riku again faces Ansem at the end of his journey, the whole adventure is revealed to be a trap by the Organization that results in Sora falling into slumber (again) and Riku ''again'' has to save Sora from what would otherwise be an endless sleep. This time however, [[TookALevelInBadass Riku is able to rescue Sora]] without having to pay the steep price he did in ''VideoGame/KingdomHearts358/2Days''.

** This is also the last time Creator/RussiTaylor voiced Minnie Mouse in the series before her death in 2019.

* FanNickname:
** Sora and Riku's dual attack during Nightmare's End/Mirage Split has earned the name the Ball Buster Keyblade.
** [[spoiler:The Xehaborg]] and [[spoiler:Borganization XIII]] for [[spoiler:the real Organization XIII]] after they attempt to [[spoiler:turn Sora into a Xehanort vessel]].
*** [[spoiler:Organortzation XIII]] and [[spoiler:Organization XIII-2]] seem to be picking up steam, especially the latter.
*** [[spoiler:Braignort and Isanort]] to mirror Terranort.
*** Some use [[spoiler: Soranort]] with the same aforementioned parallel when discussing [[spoiler: Sora falling to darkness and becoming a vessel.]]
** Some fans also like to refer to Young Xehanort as "Trollanort" due to [[spoiler:his boss battle being ThatOneBoss]].
** Portmanteau names such as Axelea and Xigbraig have been popping up as of this game, mostly to signify you're talking about the character in general, rather than a point of time in their life.
** Kingdom Hearts: {{Film/Inception}} [[spoiler:Riku's inside Sora's dreams in the Dream World, then goes further into his own dreams to defeat his personal foe near the end of the game.]]
** "Norted" or "Xehanorted" has become the term for [[spoiler:a character becoming one of Xehanort's vessels whether it be canon or not]]. Also, "Nortification" or "Xehanortification" for the process into becoming one.
** In line with BHK and OBM for Roxas and Xehanort, there's YMX for the younger Xehanort introduced.

** Who ''hasn't'' suspected [[WesternAnimation/TheHunchbackOfNotreDame Notre Dame]] or [[VideoGame/TheWorldEndsWithYou Neku Sakuraba]] showing up sooner or later?

** None of the ''Hunchback of Notre Dame'' actors reprise their roles except for Jason Alexander (Hugo) and Charles Kimbrough (Victor), though two of them [[AuthorExistenceFailure are dead]].

** In the English version, Corey Burton pulls triple duty with Yen Sid, Frollo, and Ansem the Wise.

*** Some use [[spoiler: Soranort]] with the same aforementioned parallel when discussing [[spoiler: Sora falling to darkness and becoming a Vessel.]]

** "Norted" or "Xehanorted" has become the term for [[spoiler:characters becoming a Vessel of Darkness whether it be canon or not]]. Also, "Nortification" or "Xehanortification" for the process into becoming one.

* LyingCreator: One trailer featured the striking visual of multiple Soras falling from the sky. According to Nomura, this was an original scene not planned for the game. However, possibly due to the buzz it caused, the scene was later worked into a late-game cutscene as a visual metaphor of Sora's various visits to Traverse Town. Maybe Nomura wasn't lying at the time of the statement, but it was inaccurate by the time the game went to print.

** We also knew that ''Disney/{{Pinocchio}}'' would get a world sooner or later. Heck, we knew it in ''[[WhatCouldHaveBeen 358/2 Days]]''.

** There were originally going to be greater differences between Sora and Riku's stories. Sora was planned to return to [[Film/{{Tron}} Space Paranoids]], with only Riku visiting [[Film/TronLegacy the Grid]]--there are elements of TheArtifact here; note that Sora's plot is concerned with reconnecting with Tron, while Riku's is the one with the condensed ''Tron: Legacy'' plot. Additionally, Sora's visit in the Symphony of Sorcery would've been based on ''Disney/{{Fantasia}}'', while Riku's would've been based on ''Fantasia 2000''.
** There's DummiedOut data of [[https://www.youtube.com/watch?v=rJDe41jQdNc a texture-less ship]] that resembles the one in ''Disney/TreasurePlanet'', suggesting that a world for it was planned.

* ActorAllusion: In Disney/TheHunchbackOfNotreDame, Creator/CoreyBurton voiced one of Frollo's {{Mooks}}. In this game, he [[TheOtherDarrin voices Frollo himself]].

** KingdomHearts: {{Film/Inception}} [[spoiler:Riku's inside Sora's dreams in the Dream World, then goes further into his own dreams to defeat his personal foe near the end of the game.]]

* NoExportForYou: Despite ''Nintendo Of Europe'' getting the rights to publish the game in Europe, due to Creator/SquareEnix's rather unfortunate decision to [[OfferVoidInNebraska not localize the written text for Italy and Spain]], ''Nintendo Ibérica'', the latter's subsidiary of NOE, [[http://eu.square-enix.com/en/blog/product-information-kingdom-hearts-3d-updated has now decided not to publish the game anymore.]] This means that, despite the UsefulNotes/Nintendo3DS' RegionCoding no longer being an issue due to the PAL version of the game still getting released in other European countries, Spanish fans will have to import the game anyway (unless they find said PAL version of the game at "select retailers").

** Also, a [[UpdatedRerelease HD Remaster]] of this title contained within the [[WordSaladTitle "HD 2.8: Final Chapter Prologue"]] [[CompilationRerelease collection]] for the [[PlayStation4 PS4]] was released in the year of the franchise's 15th anniversary.

** Ben Diskin takes over [[spoiler:Young Xehanort]] from David Gallagher, who voiced him in ''VideoGame/KingdomHeartsBirthBySleep''.

** None of the movie actors return to voice the characters, Creator/FredTatasciore reprises his role as Kevin and CLU from the ''VideoGame/TronEvolution'' game and ''WesternAnimation/TronUprising''.
