This is where the events of a work are made into a film or book that is considered BasedOnATrueStory, or similar, [[InUniverse within the story itself (but not outside it)]]. This often comes with LegendaryInTheSequel.

[[folder:Anime and Manga]]
* ''Anime/MacrossDoYouRememberLove'' is usually referred to as a movie made after the actual events of ''Anime/SuperDimensionFortressMacross'' -- in the ''Anime/{{Macross}}'' universe it's essentially "based on a true story."
** This is [[LampshadeHanging lampshaded]] in ''Anime/{{Macross 7}}'', in which Mylene and Basara appear in a remake of the movie, and Max and Miriya (who were there for the original events) comment on some of the exaggerations and distortions therein.
** ''Anime/MacrossFrontier'' had an episode which adapted the events of ''Anime/MacrossZero'' into a movie, which was mainly an excuse to lavishly reanimate some of the more distinctive bits of ''Anime/MacrossZero'', as well as allude to similarities between the characters of both series. It was based on ''[[GratuitousEnglish Bird Human]]'', the biography of one of the main characters of ''Anime/MacrossZero''.
* [[AudioAdaptation Sound Stages]] reveal that ''Anime/MagicalGirlLyricalNanoha TheMovie First'' is an actual film being produced in the Nanohaverse about the childhood of Nanoha and Fate, with those two serving as technical advisers to make sure that the facts are reasonably accurate and that the battles are as realistic as possible.
** This come back in the ''second' movie, which has a fairly large rewriting of the story [[spoiler:because a good chunk of the plot in the series was driven by a high-ranking TSAB officer gone WellIntentionedExtremist.]] One shudders to think of what this means for [=StrikerS=]...
* ''LightNovel/{{Baccano}}'' the first light novel, ''The Rolling Bootlegs'', begins with a Japanese tourist being told the events of the book by a mysterious young man, who is later revealed to be [[spoiler:Firo Prochainezo]].
* The manga version of ''Manga/ChronoCrusade'' hints at this--a few chapters at the end "quote" from [[MysteriousWaif Azmaria's]] memoirs, hinting that the manga may be a fictionalized version of her book.
* ''Anime/DigimonTamers'' is possibly unique in the Digimon canon as it is set in a world where ''the Digimon franchise exists''. Takato actually has Digimon trading cards and has seen season one and two! This becomes even more interesting when the kids realize that the people who made [[spoiler:the Digimon used their work to start the franchise]].
* The epilogue ([[FanonDiscontinuity yeah, that epilogue]]) of ''Anime/DigimonAdventure02'' seems to suggest that the whole series was [[spoiler:Takeru's book]].
* ''Anime/YuYuHakusho'', in the anime at least, is revealed at the end of the penultimate episode to be a compilation of footage taken by Spirit World as they monitored Yusuke's adventures.
* ''LightNovel/HaiyoreNyarkoSan'' reveals that the beings of the Literature/CthulhuMythos were simply members of alien races, and in particular one Nyarlathotepian told Creator/HPLovecraft stories from space that he turned into the Mythos. However, it's unclear just how accurate the stories are; the series remains vague as to whether or not title character is '''the''' Nyarlathotep or simply a member of the same race with the same name and a vastly different personality.

* In Marvel Universe continuity, there is a "Marvel Comics" company that re-tells the exploits of various heroes as comic books. They're quasi-journalists, and their work is thus used as historical research in legal comedy series ''She-Hulk.'' In continuity, [[Comicbook/FantasticFour the Fantastic Four]] regularly popped by the Marvel offices to lambast the staff who were supposed to be telling their stories over plot elements that they didn't like. Similarly, [[ComicBook/CaptainAmerica Steve Rogers]] not only lectured writers and editors for making him too violent, but also at one point ''penciled his own comic.''
** Most issues of ''What If?'' are told by the Watcher, who watches not just the usual Franchise/MarvelUniverse, but the whole multiverse.
** Also in Marvel Comics, ''The Sentry'' originally was based on a supposedly lost series of comics from the golden age, featuring a more traditional invulnerable-and-superstrong character. The new series dealt with why nobody remembers this classic character existing before in a very meta-way. They come up with a save-the-world explanation in the fictional universe for his fictional nature... then it gets complicated.
** Both the ''Comicbook/PatsyWalker'' humour book and the original version of ''The Two-Gun Kid'' are explained as being works of fiction in the Marvel Universe based very loosely on the canonical characters, making them a sort of Untrue Story in My Universe.
* Most citizens of Marvel Earth believe the Literature/{{Frankenstein}} Monster to be a fictional character, and don't realize Shelley's novel was based on real events. Ditto for almost every character from [[ComicBook/TheMightyThor Norse]] and [[ComicBook/TheIncredibleHercules Greek]] mythology.
* Creator/DCComics exist in the DCU. They use superheroes' status as public figures to publish "true crime" stories about their adventures.
** ''Franchise/{{Superman}}'' gives all the profits of his comics to charity.
** The ComicBook/TeenTitans have one. Impulse gave the company their [[WhatAnIdiot real names]] because he didn't know that wasn't how everyone did it. He called Superman "Dirk" for months.
** Batman does appear in the DCU's DC Comics; a late 1960s Batman comic's plot revolves around the (DCU) Batman comic and its writer.
** Barry Allen's Flash knew of Jay Garrick's Flash through comics before he learned the fella existed in another universe/sealed-off reality.
** ''Comicbook/CaptainCarrotAndHisAmazingZooCrew'' uses this aspect in its Earth-C setting: Cap himself works for his world's DC Comics, which publishes adventures of the (fictional to them) "Just'a Lotta Animals"... eventually discovering that the characters were real, existing on the parallel world of "Earth-C-Minus." The story even involves the heroes consulting Earth-C's Gardner Fox -- an actual fox, natch -- for advice on this phenomenon.
** Creator/MarkMillar wrote a story for a ''Flash'' 80-Page Giant called "Your Life Is My Business" in which his DCU counterpart chatted with Wally West about possible story ideas. This briefly alluded to the fake secret identities used in comics before so many heroes went public, and had various practical reasons why some stories couldn't be used (such as one featuring Zatanna's pre-teen descendent from the 30th century; he can't appear in a comic without his parents' permission, and they're still in the future).
** In ''ComicBook/TheMultiversity'', the comics of the various Earths of the DC multiverse recount the adventures of the heroes of ''other'' Earths in the multiverse, harking back to the Flash and Captain Carrot examples above.
* IPC's comics used this frequently.
** ''ComicBook/TwoThousandAD'' had (and still has) The Mighty Tharg, an alien on a quest to strengthen humanity by exposure to 'Thrill-power', which he does by publishing a comic.
* Goody Two-Shoes was a supervillain. Kinda. He appeared only once, had nuclear-powered shoes, and kicked the hell out of the Thing by himself. Then the Thing managed to defeat his terrible foe. ''Then'', the "real" Thing read the comic-book and went to the editorial [[YouWouldntLikeMeWhenImAngry absolutely pissed]]. We realize then that Goody Two-Shoes was defeated with [[OneHitPointWonder a flick from the Thing]], and they made up the whole fight to make the story interesting. Then the Thing does them something... uh... ''interesting''.
* Creator/AlanMoore takes this to its logical extreme in ''ComicBook/TheLeagueOfExtraordinaryGentlemen'', in an AlternateUniverse of Victorian England wherein ''all'' of 19th-century fantasy and detective fiction was based on true events, as was much of what came before.
** That was to start with. Recently, [[WordOfGod it turns out]] it's a universe in which all fiction is true. But yes, we have things like [[Literature/{{Dracula}} Mina]] being familiar with [[Literature/KingSolomonsMines Allan Quatermain]] through having read Creator/HRiderHaggard's accounts of his adventures.
** Creator/AlanMoore claims to have met John Constantine of ''Comicbook/SwampThing'' and ''ComicBook/{{Hellblazer}}'' fame in real life, more than once... Maybe he just ran into [[ComicBookFantasyCasting Sting]] and he happened to be in a trenchcoat and a playful mood.
*** We must consider two very distinct possibilities. Either Alan Moore is out of his friggin mind, or that [[{{Tulpa}} he believes so much in certain things, that they become real,]] and his sanity forces him to forget lest he obliterate himself. (The latter does in fact broadly fit his belief system.)
* In ''ComicBook/AstroCity,'' comic book companies publish titles based on both their own fictional characters and licensed real-life supers. The ones based on real heroes are more popular, but are also required to stay within known facts; Manny Monkton of Bulldog Comics repeatedly gets into trouble when he pushes the boundaries.
** The end of the "Dark Age" arc reveals that the entire story is an [[BasedOnATrueStory embellished novelization]] of what had happened in-universe, with some details changed, including the real names of the main protagonists.

[[folder:Fan Works]]
* The universe of ''Fanfic/TheKamikakushiSaga'' depicts ''Anime/SpiritedAway'' as an adaptation of a book by the actual Chihiro.
* The ''Comicbook/CaptainCarrotAndHisAmazingZooCrew'' DarkerAndEdgier AU ''The Harmony Trap'' has the regular CC&HAZC continuity as a comicbook based very loosely on the "true" events.
* In the [[Fanfic/TheElementsOfHarmonyAndTheSaviorOfWorlds Hasbroverse]], Megan Williams wrote children's books titled ''My Little Horsey'' based on [[WesternAnimation/MyLittlePonyTVSpecials her adventures]] [[WesternAnimation/MyLittlePonyTheMovie with]] [[WesternAnimation/MyLittlePonyAndFriends the ponies]]. It was soon after everyone on Earth knows of the existence of Equestria did they realize those stories are in fact true. Conversely, Megan's exploits in Equestria have become ShroudedInMyth, and "The Mag'ne" is now only slightly less revered than fully-accredited {{Physical God}}desses Celestia and Luna. Megan is not terribly comfortable with this.
* The plot of [[ Tomica Hero Rescue Pups]] revolves around ''Series/TomicaHeroRescueForce'' turning out to be an autobiography of the Rescue Force's real adventures. A remnant of that show's main antagonist, Neo Terror [[spoiler:which later unites with a [[Series/TomicaHeroRescueFire Jakaen]] remnant]], rises up to wreak havoc on Adventure Bay, and with the Rescue Force's help, the ''WesternAnimation/PawPatrol'' fights back as a combination of ''Franchise/PowerRangers'', ''Franchise/StarWars'', and ''VideoGame/{{Bayonetta}}''.
* ''Blog/AskErnstStavroBlofeld'' is set in a world where the classic Franchise/JamesBond movies are [[LiteraryAgentHypothesis documentaries/biopics based on the career of a real secret agent]]. The Creator/DanielCraig reboot films were created because the producers had to start making things up when the real Bond retired after Blofeld was arrested. Blofeld accuses Bond of sometimes [[ExecutiveMeddling meddling in the film production]] to give himself a HistoricalHeroUpgrade or make Blofeld look stupid.

* Early drafts of the script of ''Franchise/StarWars'' describe it as having come from records called the "Journal Of The Whills." Given how much George Lucas has muddied the waters, though, it's hard to know ''what'' he intended in 1977.
** George Lucas later said that the entire ''Star Wars'' saga is being told by R2-D2 (which probably is why he's always saving the day).
** [[ According to Chris Cerasi]], the six films, and the films ''alone'', are the only installments that should be taken at face value. All of the [[Franchise/StarWarsExpandedUniverse Expanded Universe works]] are really considered "retellings" of events that happened.
* The CultClassic ''Lobster Man from Mars'' is about an amateur film-maker showing a producer his debut movie ''Lobster Man from Mars''.
* ''Film/TheBlairWitchProject'' [[DirectLineToTheAuthor billed itself]] as a [[{{mockumentary}} documentary]] that [[DirectLineToTheAuthor included found footage]]. According to the movie poster, ''Film/BookOfShadowsBlairWitch2'' has a card at the front that explains that a group really did go on a killing spree after watching the first Blair Witch, and the first Blair Witch is treated as fiction. "Book of Shadows" is a dramatization of these events, and "Shadow of the Blair Witch" is the documentary of these events.
* The Spanish film ''Voyage to Nowhere'' (1986) features an old Carlos Galván telling the story of his life to a biographer. In those scenes, Galván himself admits that his recalling of events cannot be 100% correct and, at some points, he had intentionally taken another people's sentences as if they had been his. Simply because it looks cooler that way, you know.
* ''Copacabana'': a performer-turned-agent (played by [[Creator/MarxBrothers Groucho Marx]]) gets his girlfriend (played by Creator/CarmenMiranda) two separate, simultaneous gigs at the Copacabana - one as herself in the main room, and as "Madame Fifi" in the nightclub. At the end of the film the owner of the Copacabana decides to make a film about it, starring them, and we see the Big Production Number in the film.
* ''Film/{{Scream 2}}'' has the movie ''Stab'', which is the in-universe movie made about the events of ''Film/{{Scream|1996}}''.
* In ''Film/TheHumanCentipede 2'' the previous film is shown to exist on DVD.
* Mentioned in ''Film/{{Hook}}'', the film "sequel" to ''Literature/PeterPan''. Wendy Darling and Peter Pan had adventures that Wendy later told to J.M. Barrie who, we presume, made a few changes, which accounts for the inconsistencies between the book and film. For example, Captain Hook is eaten by the crocodile in the book whereas in the film, Hook escaped the crocodile and killed it instead.


* The ''Literature/HeraldsOfValdemar'' books by Creator/MercedesLackey may possibly be an example -- frequent reference is made to Herald-Archivist Myste (Lackey's AuthorAvatar; her nickname is "Misty") who is occasionally said to be collecting accounts of the adventures recounted in the books.
* The comedy/crime novel ''Jimmy the Kid'' features some bumbling crooks who plan out a kidnapping based on a novel, ''Child Heist'' by Richard Stark. While ''Child Heist'' doesn't actually exist, Richard Stark is another pseudonym of ''Jimmy the Kid'''s author, Donald E. Westlake. This makes the latter novel an extended running gag on this trope, as Westlake pretends that ''Child Heist'' exists within Jimmy's world.
* Much of the plot of Bram Stoker's ''Literature/{{Dracula}}'' is ''about'' the construction of the book itself and how Mina Harker's compilation of the characters' journals, interview transcripts, and the like helps the characters deduce {{Dracula}}'s identity and nature and ultimately defeat him. To some extent, the book is practically an advertisement for that wondrous new invention, the typewriter.
* In ''Literature/TheDresdenFiles'', it's heavily alluded to that ''Literature/{{Dracula}}'' was pretty much commissioned from Bram Stoker, so people would have a defence against the Black Court. In ''Grave Peril'', Harry mentions that the Black Court is almost nonexistent, thanks to that book. And, in one of the recent "extra" stories, it's pointed out that the ''Necronomicon'' was actually a Grimoire of great power -- until the White Council found it and published it all over the place, and by making it available to every minor mage and wannabe in existence, effectively nullified the power by spreading the effect over the entire world.
** In an interview with the author, a fan asked whether H.P Lovecraft was onto something in the same way. The answer - yes. OhCrap.
** It's explained in a minor book. [[spoiler: There are Outsider style grimoires that do NOT follow the 'spreading' rule. They get MORE powerful the more people believe in them. One of these is ALMOST discovered by Harry. Thomas is responsible for making sure no one learns about this kinda stuff.]]
* Both ''Literature/TheHobbit'' and ''Literature/TheLordOfTheRings'' are revealed at the end to share the same title as a book written by the lead character at the end of each (''There and Back Again: A Hobbit's Holiday'' and ''The Downfall of the Lord of the Rings and the Return of the King'', respectively). Bilbo's uncompleted ''"Translations from the Elvish"'' is claimed to be the (then-unfinished) ''[[Literature/TheSilmarillion Silmarillion]]''.
** The hypothesis was also used to excuse a {{Retcon}} of ''The Hobbit''. In the original edition of the book, Gollum is quite willing to hand over the Ring itself as a prize for winning the riddle contest -- utterly out of character given the plot of ''Literature/TheLordOfTheRings'', so later editions change that scene. The preface of ''Literature/TheLordOfTheRings'' justifies the correction by noting that Bilbo himself wrote the original ''The Hobbit'' as memoirs and, already slightly corrupted by the Ring, lied about how he got it when he put the tale to paper; Gandalf eventually talked him into revealing the truth.
** The ''Red Book'' itself is said to have a companion volume of ''"Translations from the Elvish"'', which presumably contains the source material of ''Literature/TheSilmarillion''. Many of ''those'' texts are attributed to specific Elvish scribes.
*** The Akallabêth (one of the stories in ''Literature/TheSilmarillion'') is attributed to Elendil, a Man, and supposedly came from a copy of the Red Book as preserved in Gondor, rather than as one of Bilbo's translations.
* ''Literature/{{Inferno}}'', a modern retelling of the ''Inferno'' from Dante's ''Literature/TheDivineComedy'', mentions that Dante's description and maps of Hell are accurate, and have been used by other visitors. Phlegyas, boatman across the swamp in the fifth circle, is particular annoyed that Dante gave away the phrase that means he has to transport the speaker to the City of Dis.
* Bertie Wooster, narrator of the ''Literature/JeevesAndWooster'' series, makes several references to himself as the author.
* In the ''Literature/KnightAndRogueSeries'' Makejoye writes a play about a handsome but poor lad and a dashing bridand who was forced into a life of crime thanks to corruption in politics competing for the same lovely high class lady who'd run away from her uncle. Just in case it's not obvious that the play is really about the actor Rudy, the unredeemed Michael, and the runaway Rosamund, he has all of them playing the appropriate roles.
* ''Literature/HouseOfLeaves'' is about a film, but it is also about a man named Zampanò writing a critical essay on the film, and it is also about a guy named Johnny Truant reading the critical essay about the film after finding Zampanò's body. Some of the dramatic tension in the story comes from the fact that, while the film itself is non-fiction, and Zampanò's essay is nonfiction and references multiple other reviews of the film, Johnny is unable to find any evidence that the film ever existed.
* In ''The Sign Of Four'', Literature/SherlockHolmes comments that he's read the account Watson titled ''A Study In Scarlet'', and wasn't impressed. He is equally scathing about Watson's continuing efforts in other stories, including one that he narrates himself.
* The pronunciation guide at the back of the ''Literature/{{Deverry}}'' books by Katherine Kerr includes references to an ongoing fued between the author and a professor of Elvish about the simplifications she uses. There are also a few references in the text itself suggesting that the books were written by a Deverrian, some centuries after the period in which they're set. The final book names this author as Cadda Cerrmor, which in Deverrian would be pronounced "[[AuthorAvatar Katha Kerr-mor]]".
* As of ''First Amongst Sequels'', the first three ''Literature/ThursdayNext'' novels sort of exist in the Nextiverse, although they're very different to the real world versions. [[spoiler: Until Thursday alters them to match our versions, just as she did to ''Literature/JaneEyre'' in the first book.]] Thursday's unwanted fame has therefore increased, and worse yet, people expect her to act like the fictionalised version.
* Fox's memoir in ''{{Literature/Inda}}'', which details the events of the Inda books, exists in two versions within the Sartorias Deles universe - one is heavily abridged and used as propaganda for his descendants, and the other is apparently a much more detailed, accurate version that very few people are aware of and which is hidden in a secret chamber in what was once his home.
* Played with in ''Literature/TheLaundryFiles'': despite the fact Bob Howard lives in a world where {{Eldritch Abomination}}s are expected to destroy the world any day now, and the government has a peace treaty with the Deep Ones, he's clear that the works of Creator/HPLovecraft should ''not'' be considered factual. They're closer to reality than most people realise, but HPL was writing fiction, not history. Mostly.
* Creator/MichaelConnelly's mystery novels (all in his Harry Bosch universe):
** ''Literature/ThePoet'' received a direct sequel in ''Literature/TheNarrows'', and the further adventures of ''Poet'' protagonist Jack [=McEvoy=] were later told in ''Literature/TheScarecrow''. In both of those later novels, ''The Poet'' is a true crime book written by [=McEvoy=].
** The Creator/ClintEastwood movie ''Film/BloodWork'' was an adaptation of a Connelly novel. In ''Literature/AngelsFlight'' protagonist Literature/HarryBosch sees a poster for ''Blood Work'' and remembers that it's a BasedOnATrueStory thriller about a case involving a friend of his. In the later novel ''Literature/TheNarrows'', a character complains about how he was portrayed in the ''Blood Work'' movie.
** ''Film/TheLincolnLawyer'' was a film about a notable case the title character, Literature/MickeyHaller, was involved in, making it BasedOnATrueStory InUniverse. The book spawned dozens of imitators and the courthouse he frequents becomes littered with Lincoln Town cars.
** Harry Bosch does not appear in the Connelly novel ''Literature/TheLateShow'', but a murder victim is an aspiring actress who was an extra in an episode of ''Series/{{Bosch}}''. Turns out ''Bosch'' the TV show is a true crime drama based on the exploits of Detective Bosch.
* ''Literature/ReadyPlayerOne'' opens with the main character explaining that many people tried to write his story (in various mediums, like games and movies) and everyone fell short or got something wrong, so he's writing the book to clear things up.

[[folder:Live Action TV]]
* Some people believe that the show ''[[ShowWithinAShow Wormhole X-Treme!]]'' is actually a way to create plausible deniability for a real Air Force project called "[[Series/StargateSG1 Stargate]]". As the Air Force will tell you, this is a complete lie.
** Of course, not only is that what they'd say if it ''was'' a complete lie, its ''also'' exactly what they'd say if it was complete truth. Not that anybody ever saw the show. [[SelfDeprecation It was on cable, after all]].
* The series finale of ''Series/StarTrekEnterprise'' was controversially framed as a non-interactive holodeck recording being viewed by ''[[Series/StarTrekTheNextGeneration Next Generation]]'' characters Troi and Riker, who occasionally paused the episode to discuss things. Early rumors suggested that the entire ''series'' would be revealed to be a holodeck recording (or worse, a simulation), but there's no evidence of this in the aired episode. A lot of fans still found it to be an inadequate send-off, although others who viewed it as a send-off to the entire franchise (since, for the first time in 20 years, there were no further ''Star Trek'' shows or movies in the pipeline, and, as of now, this is the last ''Star Trek'' show or movie set in the original continuity) were a bit more accepting of the shifted focus.
** Of course, this allowed some of the fridge logic to ret-con the episode as a piece of doctored history.
** As was done by the ''Enterprise'' novel ''The Good That Men Do'', which proposes that what Riker watched was Trip's ''[[FakingTheDead cover story]]'', and that he'd really gone undercover in Romulan space. The novel verse takes this explanation and runs with it.
* ''Series/{{Supernatural}}'': In ''Monster at the End of the Book'', Chuck is seeing visions and writing them down, believing them to be fiction. However, it turns out later that they are [[spoiler: a divine prophecy telling the actions of the main characters, and that his writings will eventually become holy texts.]]
* There's a popular fan theory that the ''Film/DrWhoAndTheDaleks'' movies, loose adaptations of ''Series/DoctorWho'' storylines "The Daleks" and "The Dalek Invasion of Earth", are in-universe movies made with some involvement from Ian and Barbara, the companions in both of those stories. This theory almost got AscendedFanon treatment in "Day of the Doctor" - Kate Stewart was supposed to have the movie posters on her wall - but they couldn't afford the rights to the posters.

[[folder:Tabletop Games]]
* It should be noted that giving samples of "genuine in-world text" is one of best methods to demonstrate a setting's flavour and encourage non-[[OutOfCharacter OOC]] style.
** In this way, ''TabletopGame/{{Warhammer 40000}}'' rulebooks (and to some extent, the novels and other works) are supposed to be propaganda, either by the faction they relate to, or by the Imperium of Man. (This provides a neat [[UnreliableNarrator get-out clause]] for any {{plot hole}}s or {{continuity snarl}}s.)
* ''Literature/TheDresdenFiles'' [[TabletopGame/TheDresdenFiles RPG]] is presented as a draft version of an in-universe RPG based on the setting, with notes and queries by assorted characters, and text marked for deletion with angry notes from Harry Dresden about not giving away White Council secrets.
* Many of the recent ''TabletopGame/BattleTech'' universe books are seen as this, being collections of news, dissertations and rumors. In ''Brush Wars'', the text even ''argues with itself'' at some points, and one page-long portion is written in a partial substitution cypher to simulate a botched transmission of a message.
** There are a half dozen hints (one of which had to be decoded by the reader in order to be understood) across 4 different books released in that last 5 years that hint at something that makes a lot of sense, that [[spoiler:Clan Wolverine joined Comstar after fleeing the Homeworlds, and during the next 300 years quietly gained significant influence over the organization, and after the Word of Blake Schism have nearly complete control over Word of Blake. The point of all of this was to try to unite the Inner Sphere under their leadership against the eventual clan invasion.]] The rumors surrounding what happened to them are among the oldest in canon, with the very first ground work laid years before the clan invasion event, which started in ''1988''. More and more rumors were added over the following 2 decades, weaving a murky and complicated tapestry of half-truths, rumors, and questionable intelligence reports. Even among diehard fans, the above spoiler is open to question, as the actual events that make the connection happened centuries ago in canon. Deep and complicated mysteries are quite at home in a universe with 800 years of history, including a 300 year period with maybe 2 decades of peace, in fact things being lost into the pages of history and coming back, (possibly with a vengeance) are a recurring theme in TabletopGame/BattleTech.
* ''TabletopGame/DungeonsAndDragons'' is [[ImpliedTrope implied]] to be this in the ''TabletopGame/D20Modern'' Urban Arcana setting (at least in BroadStrokes fashion). The adventure in the sourcebook mentions that the first mage you encounter runs a bookshop with a tabletop RPG section, drinks coffee from a "World's #1 wizard" mug, and D&D is the game that started it all. Plus, you met Estevan from the "Planar Trade Consortium", both being important actors in the Planescape D&D setting, who explicitly makes trips between the shadow and the modern world.
* In a bit of a TakeThat, the ''TabletopGame/HeavyGear'' RPG showcases that the ''WesternAnimation/HeavyGear'' cartoon exists InUniverse and the many, ''many'' things that it got wrong from the RPG universe were the result of some misguided attempt at using it as a propaganda piece.

* One of the Cursed Artifacts in ''VideoGame/GhostbustersTheVideoGame'' is a DVD of the movie ''Ghostbusters''. In the item's backstory, it was brought into the past by the Cult of Gozer in an attempt to see what the future would bring.
** Interestingly, the movie itself is a fictionalization in ''WesternAnimation/TheRealGhostbusters''.
* According to the ''VideoGame/TeamFortress2'' tie-in comics, the game itself is a "documentary" based on the events of the comics.

[[folder:Western Animation]]
* One episode of ''WesternAnimation/TheLegendOfTarzan'' focused on an American writer named Ed who hears about Tarzan's exploits and interviews people about them, eventually meeting Tarzan and Jane themselves. Of course, the episode ends with the finished book and the name Creator/EdgarRiceBurroughs on the cover.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' has a series of popular novels featuring an Indiana Jones expy. When the author announces that her next novel will be delayed, the mane characters discover that the author is writing about her own exploits.
