History Trivia / Doom

** The Sega Saturn port got hit with this as well. Originally, developers Rage Software created a custom engine that made full use of the system's formidable 2D rendering abilities, and would have run at double the frame rate of the [=PlayStation=] version while losing only a couple of graphical features. Unfortunately, John Carmack of all people vetoed the use of this engine, as one of the downsides of using the Saturn in this way was texture distortion, [[ForWantOfANail which was a deal-breaker as far as he was concerned]]. This resulted in the development team having to hastily tear out the rendering engine from the previous [=32X=] version (the Saturn used the same CPU and a very similar graphics chipset to the [=32X=]) and slap it in, resulting in the finished product suffering from poor performance and noticeably inferior visuals to the [=PlayStation=] version.

* OldShame:
** Creator/KarlUrban does not think highly of his time on this movie.
** The film is also this for Creator/DwayneJohnson. In a 2009 interview, he described the film as an example of "trying and failing" to do a good video game adaptation as well as a cautionary tale of what "not to do," and also [[https://twitter.com/TheRock/status/984852480587513856?s=19 called the movie a "stinker" on Twitter]] while promoting ''Film/{{Rampage|2018}}'' ([[https://twitter.com/DOOM/status/984879084101566466 to the chagrin]] of the official ''Doom'' Twitter).
** Creator/RosamundPike [[https://www.youtube.com/watch?v=ZfXszavE4Ig&ab_channel=ColliderExtras went on the record in 2021]] stating that she feels some embarrassment and guilt over the film's outcome since she believes she didn't do sufficient background research into the ''Doom'' world and what it meant to fans. She also stated that she applied her lessons learned regarding the importance of understanding the fan culture surrounding an adaptation to her prep for her lead role in ''Series/TheWheelOfTime2021''.

** The "Ouch Face" was an expression for the status bar head in the middle of the HUD that was supposed to show if the player received more than 20 damage at a time. In practice, the code was written in such a way that it would only appear if the player took damage and ''gained'' at least 20 health during the same tic, something that was extremely unlikely to occur without the player actually trying to make it happen. The "Ouch face" is fixed in many source ports (such as Boom and [=ZDoom=]) and was officially fixed in the 2019 Unity ports after an update.

** The [[PortingDisaster infamously bad]] 3DO port almost had one more reason to add to its infamy. According to the port's lone programmer, Rebecca Heineman, [[https://twitter.com/burgerbecky/status/675578504352673793 the 3DO version nearly had live-action]] FullMotionVideo cutscenes. Other fans [[https://www.doomworld.com/vb/post/1375471 managed to dig up more stills]] of these supposed cutscenes in all of their SoBadItsGood glory.

* FakeAmerican: Creator/KarlUrban (New Zealand) and Creator/RosamundPike (British) as siblings John and Samantha Grimm. Raz Adoti as Duke and Dexter Fletcher as Pinky.

* FollowTheLeader: While its existence owed primarily due to the term "first person shooter" having not yet been coined, there's a good reason they were called "Doom clones" for a good while -- nearly every other game in the genre made between this game's release and that of ''VideoGame/GoldenEye1997'' take some very obvious design cues from this game, such as the mazelike level design, a progressively stronger weapon hierarchy, secret areas, simple enemy AI, and basic "get to the end" objectives. This is evident even in the best-received FPS games following ''Doom'', and as a result this term is still occasionally used to refer to games clearly inspired by it as there were ''many'' of them.

* IKnewIt: For many years, fans have theorized that Doomguy is related to [[VideoGame/{{Wolfenstein}} B.J. Blazkowicz]], even hinting at being his descendant in ''Wolfenstein RPG''. On January 30th 2018, Tom Hall and John Romero both [[WordOfGod confirmed]] on Twitter that Doomguy is [[VideoGame/CommanderKeen Billy Blaze]]'s son and B.J.'s great-grandson.
