* The first song of ''Theatre/JasperInDeadland'' mostly takes place in a Flashback showing key moments of Jasper and Agnes's friendship. During this scene, Jasper envisions several copies of Agnes talking to him. Initially this seems like exposition and a unique way to have multiple actresses singing while also having all the focus on Agnes, but the main reason is to [[spoiler:hide Agnes's identity so it can be a surprise later]] while also having her appear on-screen at the beginning.

** The reason why Knuckles is SuperGullible is [[https://www.gameinformer.com/b/features/archive/2016/06/23/sonic-the-hedgehog-burning-questions-iizuka.aspx because]] the creators of ''VideoGame/Sonic3AndKnuckles'' wanted him to pose a credible [[TheRival rival]] to Sonic, yet convincingly pull a HeelFaceTurn by the end of Sonic's story, so that there would be [[JustifiedTrope justification]] for him being PromotedToPlayable [[AnotherSideAnotherStory in his own story]]. This was achieved by having the well-meaning guardian of the Master Emerald tricked by Eggman into antagonizing Sonic, then siding with Sonic while vowing {{revenge}} on Eggman once he realizes the truth.

* The titular character of ''ComicBook/ShangChi'' is a Chinese BruceLeeClone. The original plan was to make him fully Chinese, but editorial mandate by Roy Thomas enforced ButNotTooForeign and made him half-white. The character's creator and original writer Steve Englehart assumed it was to not alienate white audiences ("there were parts of the south that would not carry ''ComicBook/LukeCage''), while artist Jim Starlin added that he wasn't great at drawing Asian faces.

* The second edition of ''TabletopGame/DungeonsAndDragons'' was written during and after [[TheNewRockAndRoll the Satanic Panic]] attacks on the game. Accordingly, editorial policy at TSR ensured NoCampaignForTheWicked. In all canon material, [=PCs=] were to be presented as heroes doing good things, and support for AntiHero and villain [=PCs=] was dropped as completely as possible, with the removal of such elements as the assassin class and half-orc race.

* Budget and time limitations.

* [[https://www.youtube.com/watch?v=cqegufDG4d4 According to Robby London]], ''WesternAnimation/SonicUnderground'' had NoEnding to prevent a PostscriptSeason should the series have been picked up for another season (which it wasn't).

* Franchise/SonicTheHedgehog was DemotedToExtra in ''VideoGame/KnucklesChaotix'', while the titular character received ADayInTheLimelight, because Sega of Japan expected the UsefulNotes/Sega32x to be a flop (which it was), and wanted to minimize the damage the game would do to the franchise's brand image by reducing its namesake's role to [[spoiler:a cameo in the good ending's credit sequence]].

* [[AppliedPhlebotinum "Fairy dust"]] wasn't originally part of the ''Franchise/PeterPan'' mythos, but was written into later performances as a necessary component for achieving {{flight}}, as a response to children injuring themselves trying to replicate the stunts on the show and to discourage any future children from following suit.

* During development of the original ''VideoGame/SuperMarioBros1'', the TropeNamer for TheGoomba came about when play testers commented on the Koopas being too tricky to defeat. With what little space was left in the game at that point in development, the designers implemented the square-height enemy with a basic movement pattern and completely vulnerability, so that less-experienced players could have something to overcome before they face off against more difficult enemies.

** the massive number of villains who pulled {{Heel Face Turn}}s and [[EasilyForgiven got off scot-free with instant forgiveness]] was reportedly [[ExecutiveMeddling mandated by higher]] according to animation director [[https://trixiebooru.org/1788329 Ishi Rudell]], presumably to push the show's theme of [[ThePowerOfFriendship the magic of friendship]].

* ''Film/{{Jaws}}'' famously used MonsterDelay - and by extension NothingIsScarier - to prevent the audience from noticing the {{Special Effect Failure}}s associated with the shark animatronics. During production, they consistently suffered mechanical issues, making it difficult to film them for any extended duration of time, and Creator/StevenSpielberg expressed his lack of confidence in their convincibility. To work around these issues, early death scenes were shot and edited so that the audience would only see the ''impact'' of the shark attacks, rather than the shark itself.
