->''"It is necessary to create constraints, in order to invent freely. In poetry the constraint can be imposed by meter, foot, rhyme, by what has been called the "verse according to the ear."... In fiction, the surrounding world provides the constraint. This has nothing to do with realism... A completely unreal world can be constructed, in which asses fly and princesses are restored to life by a kiss; but that world, purely possible and unrealistic, must exist according to structures defined at the outset (we have to know whether it is a world where a princess can be restored to life only by the kiss of a prince, or also by that of a witch, and whether the princess's kiss transforms only frogs into princes or also, for example, armadillos)."''
-->-- '''Umberto Eco''', postscript to ''Literature/TheNameOfTheRose''.

Worldbuilding is the process of constructing a fictional universe. Strictly speaking, anything that happens in that universe "builds" it, so "worldbuilding" is only used to describe the invention of fictional details for some reason other than the convenience of a currently ongoing story, up to and including [[DoingItForTheArt simply engaging in worldbuilding for its own sake]].

A common form of worldbuilding is the creation of history. This could just be a FramingDevice for a story told by a historian, but fantasy worlds regularly include historical notes for centuries of warfare and intrigue. Stories can then be written at various points along that timeline, and each of those stories will have a clear relationship to all the others. It makes the writing of serial fiction much easier, especially if the series has multiple authors. If so, the fictional universe is a SharedUniverse.

The result may sometimes be called a ConstructedWorld, conworld or (Tolkien's word) sub-creation. The term world-building was popularized at science fiction writers' workshops during the 1970s. It connotes a focus on detail and consistency. Many post-''Literature/TheLordOfTheRings'' fantasy and post-''Franchise/{{Dune}}'' ScienceFiction writers use world-building in an attempt to give their stories weight and meaning that they would not have without a well-defined setting.

Constructed worlds frequently have their own aesthetics, above and beyond the aesthetics of the stories taking place in those worlds. Some artists and hobbyists build fictional worlds with no intention of writing any stories in them--at least, none more detailed than historical documents.


[[folder: Worldbuilding has two separate meanings: ]]

* The creation of a FantasyWorldMap, history, geography, ecology, [[{{Mythopoeia}} mythology]], several different cultures in detail, and usually a set of "ground rules", [[MagicAIsMagicA metaphysical]] or otherwise. Sometimes, such worlds will have a CreationMyth that's either hinted at or told in more detailed fashion. This kind of worldbuilding can go to the extreme of working out entire [[ConLang constructed languages]]. Authors typically revise constructed worlds to complete a single work in a series.
* The work that goes into deciding the details of a setting. It's very difficult to write a story that contains absolutely no imaginary elements beyond what's described to the reader, so nearly every author worldbuilds a little bit. Some, however, go above and beyond the call of duty in that regard, in which case the sheer amount of [[NarrativeFiligree detail not immediately relevant to the story at hand]] often serves as a major distinguishing point of their work.

Extra worldbuilding that is only referred to obliquely is a CrypticBackgroundReference. Over the course of a long running series or large persistent universe such as an MMORPG, these add up to form what is sometimes known as the "invisible book"- the portion of a story which becomes known over time without ever actually being directly described.

Wiki/TVTropes has a JustForFun/WorldCreationProject.


[[folder:Anime and Manga]]
* Kazuma Kamachi's Light Novel series ''LightNovel/ACertainMagicalIndex'' has a lot of world building.
* Shiden Kanzaki's light novel series ''LightNovel/BlackBullet'' has this with prologues, epilogues, and exposition. Unfortunately [[CompressedAdaptation most of the world building was cut out]] in the anime.
* Masashi Kishimoto's ''Manga/{{Naruto}}''
* Eiichiro Oda's ''Manga/OnePiece''
* Akira Toriyama's ''Manga/DragonBall'' is an interesting case, as Toriyama admitted that he ''never'' pre-planned anything when writing the manga.
* The alien competitive world of ''Webcomic/TowerOfGod'', and by extension, the Talse Uzer Stories.
* Yoshihiro Togashi's ''Manga/HunterXHunter'' is filled with exposition on the finer details of the story's world.
* The ''Franchise/{{Gundam}}'' franchise, given how long it's been around. This is especially true for works set in the Universal Century, which also introduced MinovskyPhysics.
* The AlternateUniverse of ''Anime/RoyalSpaceForceTheWingsOfHonneamise''.
* In ''Franchise/{{Digimon}}'' there's a load of worldbuilding, particularly in the [[AllThereInTheManual Digimon Reference Book]].
* ''Anime/CowboyBebop'' is an interesting case. While you do see bits and pieces of a what is clearly a very rich and detailed world over the course of the series, they never quite reveal enough detail to show whole picture about anything.
* Midland from ''Manga/{{Berserk}}'' and its surrounding territories, in addition to the LayeredWorld that governs supernatural occurrences in the series.

[[folder:Card Games]]
* Over the years, this has explicitly become the goal of the creative team for ''TabletopGame/MagicTheGathering''. Instead of being used to tell the story, each expansion block is now used to flesh out a different world to a remarkable degree.

[[folder:Comic Books]]
* The AlternateHistory of ''ComicBook/MegaMan''.
* The IDW continuities of ''Franchise/{{Godzilla}}'', Namely its ongoing series consisting of ''Kingdom of Monsters'', ''Godzilla Ongoing'' and ''Rulers of Earth''.
* ''ComicBook/AlbedoErmaFelnaEDF'' has this and also basically ''Universe Building'' as well, as the culture of each planet, language and many other details are painfully explained in many interesting ways.
* While Creator/MarvelComics' ''[[ComicBook/Marvel2099 2099]] Unlimited'' anthology series was best known for introducing the 2099 version of [[ComicBook/IncredibleHulk the Hulk]], it also featured a series of back-up stories featuring one-shot or minor recurring characters in order to help fill in more details about the world of 2099.

[[folder:Fan Works]]
* ''Fanfic/LostTalesOfFantasia'' takes all Creator/{{Disney}} stories and links together various elements and events to form a detailed, cohesive world that is currently being ravaged and changed by an [[WeirdHistoricalWar altered]] World War II. Its companion story, ''It's a Small World University'', takes place much later, adding to the world's timeline and history.
* One of the biggest draws of ''Fanfic/HonorTrip'' is that it takes the world-building of ''Anime/DragonBallZ'' UpToEleven with its details and plausibility.
* The world of C'hou in ''Fanfic/WithStringsAttached'', a completely original world (which is a MAJOR rarity in FanFiction), fully realized, with two vastly different cultures and mindsets, several sets of slang, and hints of a much more ordered past.
** And to a lesser extent, the Hunter's world, which [[Music/TheBeatles the four]] visit in the Third Movement.
* The crossover fic ''Fanfic/ChildOfTheStorm'' goes in for this in a big way as part of a slow build up, with quiet emphasis on the ButterflyEffect caused by the story's premise and events thereafter, integrating a number of fictional universes and remixing them to create a unique world, going into detail about how this affected the history of the world and various characters' pasts and personalities.
* The authors of ''Fanfic/GameTheoryFanFic'' have done ''a lot'' of world building for their version of the ''MagicalGirlLyricalNanoha'' universe. They've expanded on the history and culture of the setting, the magic, the nature of alternate dimensions, and much, much more.
* A lot of the interest in ''Fanfic/{{Renegade}}'' comes from how the ''Franchise/MassEffect'' and ''VideoGame/CommandAndConquerTiberianSeries'' universes interact.
* The ''Anime/PuellaMagiMadokaMagica'' fic ''FanFic/ToTheStars'' has a lot of worldbuilding about the Magical Girls and their effect on the human society in 25th century.
* ''Fanfic/{{Hivefled}}'' has quite a bit of it for [[{{Webcomic/Homestuck}} Alternia]], most notably the subjugglator religion, Dyelus, which the author has written quite a lot of ''very'' detailed meta about on their blog, as well as the trolls' [[ConLang language]].
* ''FanFic/ShinjiAndWarhammer40K'' goes into extensive detail regarding the effects of [[AfterTheEnd Third Impact]] on the world's people and politics, and then on how the characters' actions have effects that ripple throughout all levels of human society.
* The various fans of the animated show ''WesternAnimation/{{Daria}}'' have created the ''Daria Multiverse'', with various worlds, OCs, groups... there's a hell of a lot of fanon world-building for a show about a DeadpanSnarker in high school with an ongoing taste for obscure literature and pizza.
* ''Fanfic/{{Wreckstuck}}'': The central premise of the four fics is to develop the world of ''Webcomic/{{Homestuck}}''.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanworks:
** ''Fanfic/TheConversionBureauTheOtherSideOfTheSpectrum'' went from a simple TCB DeconstructionFic to a truly massive group project thanks to its massive MythArc, occasional uses of {{Lower Deck Episode}}s and AscendedFridgeHorror, co-authors wishing to avert CreatorProvincialism by exploring the war effort as it happens across the globe, and exploring the inner workings of the numerous factions and groups operating in the war and their [[MoralityKitchenSink moral standings]].
** ''Fanfic/TheElementsOfFriendship'' has plenty, moreso than the television series. References are made to creatures and nations that simply do not exist in the show's canon, as well as a UsefulNotes/ColdWar between Equestria and the Griffon nation of Orlalvov.
* ''Fanfic/SoulEaterTroubledSouls'' worldbuilds the ''Manga/SoulEater'' universe as much as it can. Its prequel, ''Fanfic/SoulEaterZeta'', is just icing on the cake.
* The universe of ''FanFic/SonicTheHedgehogHeroesOfMobius'' takes cues from all over the ''Sonic'' franchise, containing material from the games, the [[ComicBook/ArchieComicsSonicTheHedgehog Archie comic]], and ''Anime/SonicX''.
* ''Fanfic/SugarPlums'' is a ''Franchise/{{Naruto}}'' fan fiction set in Kirigakure which spends a LOT of time explaining and fleshing out the culture, history, political and economical system of an otherwise unknown setting in that world. It also spends a lot of time explaining the build up and actions that caused Kirigakure to become so bad that so many powerful shinobi defected from it as well as the events that led up to the civil war that eventually resulted in Mei taking up the mantle of Mizukage.
* ''Fanfic/PokemonNovaAndAntica'': The story takes place in the brand new, original Region of Tenla. It will inevitably showcase its own mythology, history, and culture that the story will slowly unveil to the readers.
* The Undertale FanFic ''Fanfic/{{Visiontale}}'' has world-building regarding the Underground, fleshing out the slang and customs alluded to in the story, as well as adding new terms and customs. The author explores the implications of monsterkind's altered societal development as opposed to postindustrial nations on the surface, as well as the structures in place which would allow for the mix of magic and technology present in the game.

* Part of the appeal of ''Franchise/StarWars'' was that it created a feel of an entire galaxy, with its own histories and customs, while only focusing on a handful of sparsely populated planets. The Franchise/StarWarsExpandedUniverse capitalised on this immensely, with hundreds of worlds, species and societies and histories stretching back tens of thousands of years.
* ''Film/{{Avatar}}'' had an extensive work of world building concerning the creation of the flora, fauna and culture from Pandora. The Na'vi lexicon was created by a [[http://en.wikipedia.org/wiki/Paul_Frommer real linguist]]. There is a whole UniverseBible concerning the alien language (Speak Na'vi), plants and wildlife taxonomy, a scale structure for the alien music, Pandora's physical properties etc. etc.
* Brian Froud and Creator/JimHenson did a long work of WorldBuilding before making the movie ''Film/TheDarkCrystal'', which takes place in "another world" inhabitated by many different kind of creatures, none of them based on humans or any other specific creature from Earth. Henson originally wanted the Skeksis to speak their own fictional language, with the dialogue subtitled in English.
* Every ''Franchise/MadMax'' film has been consistent (even if there are {{Continuity Snarl}}s that Creator/GeorgeMiller doesn't really care about), and each film has contributed to the post-apocalyptic world Miller has built, both being similar and yet giving a completely different view each time. This was one of the biggest points of acclaim that ''[[Film/MadMaxFuryRoad Fury Road]]'' received, with its now well-known ShowDontTell approach building everything with virtually no exposition.
* ''Film/JohnWick'' depicts a society of hitmen that functions almost entirely separately from the rest of the world. They even have their own currency in the form of gold coins (one of which is worth thousands of dollars), which are used to show that they have the skill, wealth, and reputation to belong in that society.

* Creator/ShannonHale's novels all are very lovingly crafted. However, this often results in a slow beginning.
* Creator/WilliamMorris's ''The Wood Beyond the World'', a major influence on Tolkien's own worldbuilding.
* M.A.R. Barker's ''Tékumel'' created by him beginning at age ten, for much the same reasons Creator/JRRTolkien created Middle-Earth.
* Frank Herbert's ''Franchise/{{Dune}}'' series.
* Robert Jordan's ''Literature/TheWheelOfTime'', perhaps the most famous (and complete) constructed worlds in recent works of literature.
* Velgarth, where Creator/MercedesLackey's ''Literature/HeraldsOfValdemar'' takes place.
* Creator/UrsulaKLeGuin's ''Literature/{{Earthsea}}''. WordOfGod says that, at least when working on the original trilogy, she literally made up background information as she went along, depending on what felt right. Two of the islands are named for her children's nicknames.
* Creator/CSLewis's [[Literature/TheChroniclesOfNarnia Narnia]]: he indulged in worldbuilding much less than most of the examples here; he preferred to write quickly and without bothering to establish much background information beyond what was necessary for the story. His friend Creator/JRRTolkien even criticized him for making Narnia a FantasyKitchenSink world, and for not taking the craft of worldbuilding seriously enough.
* Creator/GeorgeRRMartin's ''Literature/ASongOfIceAndFire''.
** Also, the Thousand Worlds of his ScienceFiction short stories.
* ''Literature/TheSagaOfRecluce'' by L. E. Modesitt, Jr.
* The ''Literature/KnownSpace'' and Literature/TheMagicGoesAway settings of Creator/LarryNiven.
* The ''Literature/CoDominium''.
* All of Creator/BrandonSanderson's works, in fact, they actually all share [[TheVerse a cosmology]] except for his young adult Alcatraz books, and of course the [[Literature/TheWheelOfTime Wheel of Time]] books he's written in PosthumousCollaboration with Robert Jordan, WordOfGod says there's even a defined logic that underlies all the different magic systems of all Sanderson's works.
* The Instrumentality of Mankind cycle of Creator/CordwainerSmith.
* Creator/JRRTolkien's ''Literature/TheLordOfTheRings'' - The original, [[TropeCodifier at least in the modern sense]] of the detail involved. Tolkien stated that the creation of Middle-earth was the result of giving his [[ConLang created languages]] a place to live in. He has written a lots of notes on the direction of that the history of Middle-Earth should go. Much of his notes have been organized and published as ''Literature/TheHistoryOfMiddleEarth''.
** Tolkien's world turned out so popular that [[FollowTheLeader nearly all Western (and some Eastern) fantasy took after him]].
** Tolkien's essay ''Literature/OnFairyStories'' suggests that imagining new worlds -- and new perspectives on our world -- is the highest and (literally) most ''sacred'' aim of art, and invented the term "subcreation" for it.
* Austin Tappan Wright's ''[[http://en.wikipedia.org/wiki/Islandia_(book) Islandia]]''
* Creator/JorgeLuisBorges's "Literature/TlonUqbarOrbisTertius" is something of a meta-example, being a fantasy about world-builders... [[RewritingReality who want the world they're building to]] ''[[RewritingReality replace]]'' [[RewritingReality ours.]]
* Creator/LFrankBaum's ''Literature/LandOfOz'' (begun in 1900) is perhaps one of the earliest ''modern'' attempts at world building. Maps by Baum depict Oz's four regions and its neighboring kingdoms. The worldbuilding came about because of fans clamoring for more stories and places to explore. (ContinuitySnarl ensued)
* R. Scott Bakker's Eärwa (though not the entire planet), of the ''Literature/SecondApocalypse'' series, has four thousand years of human history, three huge religions, several different species, and his very own magic. Also, a completely incomprehensible EldritchAbomination BigBad.
* ''Literature/HarryPotter'' indulges in quite a lot of this, the world growing more detailed and complex as the books go on, though for the most part it's LikeRealityUnlessNoted.
* Creator/RobertEHoward's sword and sorcery universe, which encompasses both the Hyborian Age of ''Franchise/ConanTheBarbarian'' and the age of ''Literature/{{Kull}}'s'' Atlantis.
* Creator/MichaelMoorcock's multiverse, encompassing the worlds of Elric, Corum, and various other heroes who take on the role of the Eternal Champion.
* Creator/GarthNix's ''Literature/OldKingdom'' books have a rich background.
* Mary Hoffman's ''Literature/{{Stravaganza}}'' books are set in an AlternateUniverse and AlternateHistory version of Renaissance Italy.
* Creator/DavidWeber's ''Literature/HonorHarrington'' started off less built, but after 17 doorstoppers plus 5 short story collections with several of the short stories designed to fill the history and technology roles have built up a fairly consistent world whose technology is plausible and has rather large and detailed conflicts.
** Safehold exploits David Weber being a more experienced author, and has very large global conflict with dozens of different political groups involved in a religious conflict.
* Creator/TerryPratchett wrote 38 novels along with several [[AllThereInTheManual background information books]] for his ''Literature/{{Discworld}}'' series, with [[LoadsAndLoadsOfCharacters several recurring characters]] and places.
* The Literature/VorkosiganSaga, most notably in its description of Barrayaran history and culture.
* Andrey Livadny's ''Literature/TheHistoryOfTheGalaxy'' is a vast [[TheVerse 'verse]] with over 30 novels, novellas, and short stories (and counting). The order of writing does not always match up with the universe timeline (although, currently, he seems to be primarily adding to the end). Most novels have unique characters, although there are story arcs that include several of the books. There's a reason the series includes the word "history", especially since many novels deal with alien races, most of which predate humanity by millions of years and some have stopped counting at billions. One novel even goes into the origin of life itself, and another off-handedly reveals that "true" origin of Christianity. Several fan-based web [=MMORPGs=] have been created based in the 'verse, especially set during the First Galactic War, a 30-year period of constant technological warfare between two human powers, a period so devastating that its effects are still felt 1000 years later. And now one universe isn't enough for the author, since he's expanding it to TheMultiverse with several parallel realities with completely different histories and races intersecting.
* Donald Kingsbury's ''Literature/CourtshipRite'' has a huge amount of world-building, not just in the planet Geta itself, but in the society of the LostColony, which has been there for so many centuries that Earth isn't even a legend any more.
* Creator/CharlotteBronte and her sisters and brother were masters of this at a very young age. Taking off in 1826 from a set of toy soldiers, they colonized the west coast of Africa and called it the Glasstown Confederacy, later Angria. The adventures of the "Young Men" and later UsefulNotes/TheDukeOfWellington 's son Arthur, whom they elevated into a veritable demigod, were set down in [[https://www.youtube.com/watch?v=0Z01Bzs0Dqo a set of handmade books about the size of a large postage stamp]]. Later, Emily and Anne split off and discovered Gondal, a huge continent in the Northern Pacific. These narratives were lost but for a few dozen poems. It's easy to see the origins of ''Literature/WutheringHeights'' and ''JaneEyre'' in these narratives, which went on for their entire lives.
* Creator/HenryDarger, author of ''[[Literature/InTheRealmsOfTheUnreal The Story of the Vivian Girls in What is Known as the Realms of the Unreal]]'' devoted years, beginning in about 1919, to detailing the gigantic world where most of the story takes place.
* Elizabeth Knox, one of New Zealand's most famous authors, began elaborate worldbuilding as a child and on into adulthood with her sisters Mary and Sarah. Several of Elizabeth's novels are based on events in their imaginary worlds. They discuss the intersection of their real lives with their fantasy creations in [[http://nzetc.victoria.ac.nz/tm/scholarly/tei-Ba01Spo-_div1-N11E84.html a series]] [[http://nzetc.victoria.ac.nz/tm/scholarly/tei-Ba07Spo-_N80169.html?iframe=true&width=80%&height=80% of literary]] [[http://www.thearts.co.nz/artist_page.php&aid=73&type=essay&essay_id=76 journal articles]].
* See the [[https://en.wikipedia.org/wiki/Paracosm Paracosm]] article on Wikipedia for more examples of youthful world-building which often becomes the basis for creative writing and art in adulthood.
* Brian Jacques' ''Literature/{{Redwall}}'' books have a world that not only seems to span quite a lot of territory and varied geography, but also has a history going back many generations, including books set both before and after the original.
* Tamora Pierce creates a very vivid realm in her novels about the Literature/TortallUniverse.
* ''Literature/TheRailwaySeries'': The Reverend W. Awdry and his brother gave the Island of Sodor not only a thoroughly detailed map but a complete history going back centuries.
* The ''{{Literature/Deverry}}'' series has a good bit of this over its 15 books, and it's quite necessary, as the story is told by moving to different points in the history. The author has stated that the first bit of the world that came to her mind was what ended up being expanded to be the last part of the sixth book.
* ''[[Literature/TakeBackTheSkies Take Back the Skies]]'' is set in the fictional world of Tellus, notable for the thick, tumultuous storms that surround its islands.
* ''Literature/{{Murderess}}'', the first installment in ''The Exiles of Greywall’d Saga'', has some world-building included, but only moderately; the following books in the series will develop this aspect some more.
* In the ''Literature/StarDarlings'' franchise, each book has a detailed glossary to explain terms, and goes into detail about the Starling life cycle.
* For a relatively short novel, ''Literature/AlienInASmallTown'' does a lot of this, with at least two huge wars that each had lasting consequences on the history of the setting, the "Cybertopias" full of failed transhumans, a huge orbiting "port city," human colonies throughout the solar system, and alien outposts on Mars, Callisto, Pluto, and Kuiper Belt objects.
* The Rev. W. Awdry, the author of ''Literature/TheRailwaySeries'', spent roughly four years "mapping" the Island of Sodor, which in the books, takes the place of the real-life Walney Island. The end result is a plausible world with a realistic railway network.
* J. Zachary Pike does this in ''Literature/TheDarkProfitSaga'', even though it only consists of one novel so far. Yet the book features a FantasyWorldMap at the end, as well as a glossary of terms. The author's website has a blog with detailed information on the various races, clans, and organizations in the world of Arth. There's a pantheon of gods, the origins of humankind, an ancient war between good and evil, and even the beginnings of a ConLang.

[[folder:Live-Action TV]]
* ''Series/{{Firefly}}'' has not only a map of the solar system the show takes place in as a buyable poster, but the Tabletop RPG gives us much worldbuilding.
* Creator/JMichaelStraczynski's ''Series/BabylonFive'', which has a setting with five major galactic powers and several smaller governments.
* The Twelve Colonies of ''Series/{{Battlestar Galactica|2003}}'', which were fully fleshed out by the writers for the start of ''Series/{{Caprica}}''.
* ''Franchise/StarTrek'', notably in ''Series/StarTrekDeepSpaceNine''.
* ''Series/{{LOST}}'' built up the history of the island.
* The world of ''Series/FraggleRock'' may be {{Lighter and Softer}} than most other entries on this page, but is no less complex and fascinating.
* ''Series/TheManInTheHighCastle'': There are a lot of references made about the overall state of the [[CrapsackWorld hellish world]] that the Axis Powers created in their victory, for instance Nazi Germany taking over the European colonies in Africa and replacing them with even more brutal regimes resembling the Congo Free State.

[[folder:Tabletop Games]]
* Worldbooks, a type of {{sourcebook}}, are tabletop RPG supplements that exist entirely to give {{Game Master}}s detailed settings to run their games in. While it's possible to buy worldbooks based on the real world--essentially, history books targeted at roleplayers--most worldbooks are about fictional worlds, and so the process of writing the book consisted entirely of worldbuilding.
* Many [[TabletopGame/DungeonsAndDragons Dungeon Masters]] create their own fantasy worlds for their campaigns. Some of the more famous examples of these worlds are ''TabletopGame/{{Eberron}}'' by Keith Baker and ''TabletopGame/ForgottenRealms'' by Ed Greenwood.
** There is even a "World Builder's Guidebook" giving a set of auxiliary rules for building one's own world in accordance with AD&D's mechanics. (A dice roll can result in the world being shaped as a twenty-sided polyhedron.)
* There's an offshoot of roleplaying games developing that might be called "world-building games", in which the players collaborate to tell the history of a world that develops in-play.
* ''TabletopGame/{{Warhammer 40000}}'' has an extremely well crafted setting with a complex history going back tens of thousands of years.
* ''TabletopGame/{{Warhammer}}'' doesn't have such an extensive time period to work with, but a higher number of factions and being limited to one planet means a lot more attention to small details.
* ''TabletopGame/{{Traveller}}'' deserves special mention as one of the best sci fi verses ever built.
* ''TabletopGame/BattleTech'' features a 31st century with dozens of detailed worlds and cultures, developed over the course of about three decades.
* ''TabletopGame/LegendOfTheFiveRings'' has been developed over about two decades, with a history stretching back a thousand years and a continuing storyline that has spanned generations.
* This is what ''TabletopGame/{{Microscope}}'' is all about! Players collaboratively build a world as they play in it. If a group plays long enough they can end up with a very detailed world--and maybe play more traditional RPG's set there.

* The ''Toys/{{Bionicle}}'' universe, to the point where it has in-universe mythology and creation myths ([[WillingSuspensionOfDisbelief which most members of the audience accepted in the first few years as canonical events in the timeline]]) that are later {{Deconstructed}} as [[DoingInTheWizard science-based explanations for the seemingly mystical occurrences]] are gradually revealed.

[[folder:Video Games]]
* The World of ''VideoGame/BattleForWesnoth'', although it is unique as it is a open source project.
* Akira Tsuchiya's ''VideoGame/ExaPico'' universe. To summarize, he created a universe grounded on waves and sounds, where music and feelings all have quantifiable power and serve as the basis for the physical laws in it. This complete with two planets that have extensive timelines, no less than six functional Conlangs, and even living cultures, myths and legends for the regions that exist in them.
* ''Franchise/IvaliceAlliance'' and ''Compilation of VideoGame/FinalFantasyVII''.
* The first six ''VideoGame/DragonQuest'' games are meant to be broken up into trilogies (1-3 and 4-6, with the last game in each trilogy being a prequel to the first two). However, the second trilogy bar only has a tenuous connection with the games they frame.
* ''VideoGame/{{Oddworld}}'' is a giant fictional universe presented as a video game series.
* The ''VideoGame/{{Warcraft}}'' series has grown from a fairly standard setting to this, including lore elements dating back ten thousand years or more. It has four worlds (Azeroth, Draenor, and to a lesser extent, Argus and Xoroth) which are explored in depth.
* Blizzard's other big settings, [[VideoGame/{{Diablo}} Sanctuary]] and [[VideoGame/StarCraft the Koprulu Sector]], which are both getting pretty extensive supplements.
* ''VideoGame/MetalGearSolid''
* ''VideoGame/MitsumeteKnight'' thrives on this, having a rich world and mythos described in-game and in WordOfGod notes, and this is one of the main aspects (along with the AnyoneCanDie factor) that makes it stand out in the crowd of [[DatingSim Dating Sims]]. Yep, you read that right, a ''DatingSim'' which has rich and deep WorldBuilding.
* ''VideoGame/DwarfFortress'' is something of a meta-example, as it does this the first time you play, and can be done as many times as desired. While the set of creatures, plants, and [[FiveRaces sentient races]] are well-defined in the game files, the [[{{Mythopoeia}} mythology]], history between the races, geography, and geology are [[RandomlyGeneratedLevels procedurally generated]], according to modifiable parameters. This is a huge part of the game's charm.
** This, of course, leads to events where a dwarf will erect a statue of some guy you never heard of in the middle of your fortress. Until you check the legends, you'll never know about him. When you do, you'll probably find out that he was a [[BadassNormal peasant]] who managed to singlehandedly defend a castle from a horde of cyclopes [[ShoeSlap with his left boot]].
* Creator/BioWare's original properties (well, as original as [[{{Troperiffic}} a BioWare property]] gets) tend to be quite extensively worldbuilt. ''VideoGame/JadeEmpire'' is a minor example, while in ''Franchise/MassEffect'' they went into greater detail. ''Much'' greater detail. And even ''ME'' is eclipsed by the ''Franchise/DragonAge'' franchise.
** And even when playing in someone else's universe, they like [[ShownTheirWork proving they did extra credit on their homework]] and adding huge amounts of their own mythology into it. ''VideoGame/KnightsOfTheOldRepublic'' added an entire new chapter to the Franchise/StarWarsExpandedUniverse. Codex hunting in ''VideoGame/StarWarsTheOldRepublic'' is a massive undertaking.
* ''VideoGame/BrutalLegend'' has the Age of Metal, complete with a FantasyWorldMap, FunctionalMagic based on HeavyMetal, and a CreationMyth reflecting the history of the genre.
* And of course, there are some games where ''you'' can build a world, or at least greatly influence one. Sim games are an obvious example. And the ''VideoGame/{{Fable}}'' games, amongst others, allow you to shape the future of the world they're set in.
* The Franchise/{{Nasuverse}} often makes side-references to expand its magic system without it having any relevance for the actual story. The most prominent example would be the constant mention of dragons being the most powerful of all magical creatures, though nobody ever fights a dragon onscreen.
* ''VideoGame/{{Marathon}}'' gets special credit for doing extensive world-building in a time when most FPS game stories consisted of "monsters teleport in, you kill them"
* ''Franchise/{{Halo}}'' does this with its extensive ExpandedUniverse, building an entire mythology around the series. Starting with ''VideoGame/{{Halo 3}}'', each game also had several hidden terminals/data-pads/etc. that dramatically expanded on the backstory, and later entries in the series became more heavily integrated with the expanded universe; several important plot points in ''VideoGame/{{Halo 4}}'' were explained primarily in the novels.
* ''Franchise/TheElderScrolls'' has the Aurbis, the totality of existence, which encompasses [[OrderVersusChaos Aetherius and Oblivion]], and the Mundus (which contains Nirn, the world of mortals, and the continent of central focus, Tamriel), and a few other lesser planes of existence.
* ''VideoGame/{{Solatorobo}}'' purportedly spent seven of its ten-year development cycle on world building, creating the LoadsAndLoadsOfCharacters and the various looks and cultures of the {{Floating Continent}}s.
* ''VideoGame/{{Touhou}}'' owes its gargantuan fanbase to this trope. ZUN includes a surprising amount of information surrounding the characters, events and setting of the games, enough to fill several {{Universe Compendium}}s, but it is almost always bare-bones details, prompting the fans to create their ''own'' world building in any way they can, filling whatever gaps they see.
* Most of the updates for ''VideoGame/CommandAndConquerGenerals'' GameMod ''VideoGame/RiseOfTheReds'' are this, showing the evolution of the setting post-ZH, leading to the [[spoiler:Russian invasion of Europe]].
* The ''Creator/NipponIchi'' multiverse started out pretty simple, but gets a bit more complicated as more games come out. This is usually played for laughs. In particular, Celestia and the various Netherworlds recieve a growing amount of detail as the games go on.
* The solar system of Zoincailla wherein ''VideoGame/CopyKitty'' takes place. For a game about [[RuleOfCool a cat girl shooting up penguins, cyborgs, robots, and demons with rainbow-colored lasers in virtual reality]], there's a surprising amount of detailed world building relating to the various species, culture, and environments that make up its eight planets. For instance, did you know the protagonist, Boki is from a cave-dwelling species called Kitera from a desert planet that eat gems? Or that thanks to their birthplace, her random meows peppering her dialogue are remnants of a tradition where they would use echo location? Or that thanks to being constantly attacked by creatures called Cybers from another dimension, her virtual training is to be prepared in case they come to convert her? [[PlayTheGameSkipTheStory Bet you didn't]]
* The creators of the ''VideoGame/{{Ravenmark}}'' series did that with their first game, which was largely story-driven with a map of the world, a different calendar, backstories of the different factions, the pantheon, etc. Unfortunately, the sequel is largely multiplayer-oriented, so not much is added in terms of background material.

* ''Webcomic/DominicDeegan'' has a story arc that was partly so the characters could unwind, and partly so Mookie could do some world building.
* The [[http://bobadventures.comicgenesis.com/d/20090725.html "space opera" story arc]] in ''Webcomic/TheInexplicableAdventuresOfBob'' seems to be largely intended to pull the many disparate threads of the comic together into a coherent larger setting.
* Several of the [[AnotherDimension alternate dimensions]] of Pete Abrams's ''Webcomic/SluggyFreelance''.
* ''Webcomic/SnowByNight'' takes a Colonial-like setting with [[FantasyCounterpartCulture roughly equivalent places]] and starts its world-building by taking some clever divergences from real life. The [[http://www.snowbynight.com/almanac.html Almanac]] shows it off the most.
* ''Webcomic/TheMansionOfE'' has this going on in the background as the action wanders around the eponymous structure.
* ''Webcomic/{{Erfworld}}'' doesn't just take place a world with its own cultures, and an unfamiliar set of fundamental universal laws. It features a protagonist from outside of that world learning about the world alongside the reader... who then hunts down and exploits loopholes within the world's established construction in ways that rock the world to its foundations and destabilize whole civilizations with long and (internally) storied histories.
* ''Webcomic/{{Unsounded}}'' is built on this, with an entire continent of multiple nations with their own religions, governments, even various taboos, whole industries built on FunctionalMagic, various political complexities, and intimate views into crime and [[DeliberateValuesDissonance the slave trade]].

[[folder:Web Original]]
* Terreneus in ''Literature/GrandmasterOfTheft''.
* In each compilation book of ''Monster Girl Encyclopedia'', large amount of background info were given about its world, covering how things were before, and how much it changed after the reign of Succubus Overlord. [[PornWithPlot Quite impressive one for fetish works]].
* ''WebOriginal/{{Blackburn}}'' is heavily based on worldbuilding. Much of the story is dedicated to the lore of the city, and introducing [[LoadsAndLoadsOfCharacters tons of characters who will be more important later.]]
* [[http://www.otherworldproject.com The Otherworld Project]], formerly Eshraval, is a long-running online collaborative modern worldbuilding project founded in 2004, which also encourages RolePlay in the context of the world (though not at the moment since it's rebuilding). It's recently undergone a reset, and is in redevelopment mode. Strong hints of CrapsackWorld in its current incarnation.
* Forest Bed from ''VideoGame/TheTraderOfStories''. It's [[SceneryPorn pretty]].
* The ''WebOriginal/DeviantArtExtendedUniverse'' was basically founded as an experiment in world building. Author Doctor-of-W envisioned a fantasy setting with his followers as characters, and created a planet with various locations and a sub continent within that planet as a microcosm of that world! As the story is still new, not much actual setting development has happened yet. But give it time!

[[folder:Western Animation]]
* The Land of Ooo from ''WesternAnimation/AdventureTime'' is a mild example. Ooo is meant to be AfterTheEnd, arising from the remains of human civilization as we understand it, and there are hints towards this in almost every episode, including the opening sequence. Examples include mispronunciations of names like "Mozart" and "[[Creator/TheMarxBrothers Groucho]]," and there's also a NurseryRhyme that seems to be about mushroom clouds.
* [[Franchise/AvatarTheLastAirbender The world]] of ''WesternAnimation/AvatarTheLastAirbender'' and ''WesternAnimation/TheLegendOfKorra''.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' slowly but surely embraces this trope as it progresses, whether it be key moments in the history of Equestria (its founding, [[TheDarkTimes Discord's rule]], [[FallenHero Nightmare Moon]]), the methods used to [[PaintingTheFrostOnWindows alter and control nature]] (Winter Wrap-up, weather generation), the interactions between ponies and other creatures (or non-interaction, as is the case with dragons), and many other subtle details. [[http://mlp.wikia.com/wiki/File:Map_of_Equestria_April_2013.jpg There's even a map thrown in the mix.]]
* In the early seasons of ''WesternAnimation/TheSimpsons'', Springfield semi-qualified, as its events were contained enough to function as a separate world, even if it was never defined as such. This was abandoned later on.
* ''WesternAnimation/ThunderCats2011'' implied a lot about not just Third Earth, but the entire universe, but never got around to revealing much. The animal races that were brought there after the Black Pyramid crashed have been there for about five thousand years, and have had conflicts between themselves before the start of the series. There is also mentioned other inhabited planets, but we only see one during a flashback.
* ''The Art Of WesternAnimation/KungFuPanda'' goes into some of the history of the world, such as how Master Oogway came to the Valley Of Peace and why most of its residents are pigs, geese, and rabbits. Both this and the animated shorts also show off a few important locations that never appeared in the films as well as revealing the backstories of some of the major characters.
* ''WesternAnimation/{{Trollz}}'' has a detailed system of magic, several historical events are mentioned, and in one episode the wheres and whys of how girl trolls get their magic is explained. They even have a different calendar system.
* WesternAnimation/StevenUniverse has a very detailed and complex history regarding [[SiliconBasedLife Gems]]. The specifics are mainly done for the sake of CharacterDevelopment, to give the Crystal Gems an intricate past making it clear they weren't idle before the start of the series. As the Crystal Gems are forced to confront more of their race from their homeworld, many details relating to the mechanics of Gem powers, society, and the ancient [[GreatOffscreenWar civil war fought for the sake of the Earth]] are revealed. More subtly, background shots establish shades of AlternateHistory for the Earth itself.
* ''WesternAnimation/{{Futurama}}'' includes a lot of worldbuilding in the form of jokes, and characters often make offhand references to events and people in the year 3000. There's a variety of planets and species with highly-detailed cultures, and plenty of visual gags adding to the futuristic setting, like messages in a fictional alien language that are seen in various locations throughout the series. Robots also have a very fleshed out culture, which is best seen in Bender-centric episodes.
* ''WesternAnimation/LadyLovelyLocks'' had several details given about the Land of Lovelylocks, including how Lady's Looking Room worked, how dragons were born, where Lady and Ravenwaves lived, areas outside their kingdoms like the Lake of Reflections, the Frosted Mountains, the Parched Desert, Mirror Lake, and cryptic references to the Sea of Far Beyond and lands beyond it. A [[https://i.imgur.com/LOqYsbr.png tie-in board game]] showed even more locations, some of which were used in year 2 of the toyline and in books.

* It's rather easy to do this yourself, just open up a word processor document and let your imagination take off.

* The setting of the [[PlayByPostGames forum role-play]] ''Roleplay/OpenBlue'' has, over its extensive history, grown quite large.
* [[http://www.santharia.com Santharia]] is a world-building project for the world of Caelereth, which has been going since 1998. Everything from flora and fauna to cosmology is described in loving detail, and pictures added created by Dreamers themselves. The world of Caelereth is developed on the Development board, while on a separate Roleplaying board stories are told set within this world, most of them within the continent of Sarvonia. Recently an interactive game has been developed.
* ''Fanfic/FriendsOfASolarEmpire'', being ([[CrossOver partly]]) a ''VideoGame/SinsOfASolarEmpire'' fanfic, has very little Canon backstory for any of the Sins factions. So the author ''made one''.
* ''[[http://www.valucre.com/ Valucre]]'', another [[PlayByPostGames forum role-play]], takes place on a planet twice as large as Earth, and over its twelve years of existence has amassed a huge collection of extremely detailed user-created lore. More specifically, each of the three continents[[note]]Tellus Mater is divided into four separate territories, so those have their own lore too[[/note]], territory, kingdom, city, town, and major location has a detailed article about its geography, culture, technology, government/politics, economy, transportation, and history.
