It's a simple and well received story - the main characters have explored a vast and magical realm, with limitless borders, fantastical races, and did I mention limitless borders?

The book was a hit, a veritable ''smash'', and logic dictates that a new one must be penned. But there's a problem -- the plot is resolved already. The UltimateEvil has been destroyed, the tyrant king dethroned, ding-dong the witch is dead. How do you make a new story in this world?

Simple -- expand the world.

It shouldn't be that hard. A little {{Hand Wav|e}}ing, a little {{Retcon}}, and people won't notice. Use the same heroes for consistency and you can set the sequel in a neighbouring country in the same MagicalLand!

This is effectively a PostscriptSeason for the series, but trying to create new plots from [[AssPull thin air]] can create inconsistencies. If four humans were all it took to defeat the White Witch in Creator/CSLewis's ''Literature/TheLionTheWitchAndTheWardrobe'', then how did the neighbouring, human-filled kingdoms of Archenland and Calormen not pose a threat for a hundred years?

If a work was meant to be a one-shot story and they have to expand the universe to make a sequel, they effectively have to weld new kingdoms and landmasses onto the world - adding {{backstory}} never even hinted at in the first book. And if you look close enough, you can see the seams. However, a good series will {{retcon}} these cleanly, tying back to the original material, so that we don't notice or care. An even better series ''will'' have [[SequelHook hinted at them in the first book]], either to allow for this possibility, or just to satiate the creator's sheer pleasure in world-building.

Of course, this doesn't just apply to TrappedInAnotherWorld plots; it applies to any unexpected hit with its own, original setting, even outside the SpeculativeFiction genres.

Compare with RememberTheNewGuy, which can be this applied to new characters that logically should have been mentioned before in previous works, but suddenly appear and are treated like they have always been there.

[[folder:Anime & Manga]]
* In the second season of ''Manga/MagicKnightRayearth'', it's revealed that the magic separating Cephiro from other countries is now gone. These "countries" are more similar to other planets; and it requires a ship and enormous magic/technology to traverse the gulf in between.
* They pulled the same stunt in ''Slayers Try'', the third season of ''LightNovel/{{Slayers}}''. "The magical barrier" that surrounded the Known World (whose existence wasn't even so much as ''hinted at'' in the previous seasons) suddenly vanishes, opening the rest of the world to exploration for the first time in a thousand years. It is broadly hinted at that Our Heroes defeating the BigBad in the previous season was what brought down the barrier.
* ''Franchise/LyricalNanoha'':
** ''Anime/MagicalGirlLyricalNanohaAs'' revealed more realms besides Earth, Mid-childa, and Precia's pocket dimension -- although to be fair, the fact that there ''were'' other worlds out there was made clear in the first series; we just didn't see them.
** ''Force'' outdid every series yet, by revealing worlds besides Mid-Childa and Earth, which includes the TSAB-administrated core worlds (5 besides Mid-Childa so far) and non-administrated ones. A good portion of the latter are mostly mentioned due to the involvement of the [[OmnicidalManiac Hucke]][[SerialKiller bein]].
* ''Anime/{{Pokemon}}'' has not only the regions listed in the Video Game entry below, but a few more when the anime [[OvertookTheManga ends up taking more time than the release of a game]] -- the most blatant being the Orange Islands, which are visited after the Kanto series but before Johto.
* The world of ''Manga/HunterXHunter'' parallels Earth, with major cities in the same places and the world map merely flipped with a few of the continents partially rotated. The "outside world" is implied in the Chimera Ants arc to be islands in their version of the Pacific Ocean, ''outside'' of the political monolith that rules most of the world. It is revealed in the segue to the next arc to be a land mass that makes the entire Earth-sized world seen so far as relatively small as the Caspian Sea.

[[folder:Comic Books]]
* ''Comicbook/{{Legion Of Super-Heroes}}'': In the late '60s, Jim Shooter introduced the Dominators to the title, at the end of a supposed war between them and the [[TheFederation United Planets]] that had never been mentioned before. In fact, it had been previously established that war in general was now unknown. Amazingly enough, this was repeated in the "threeboot". It was stated explicitly at the start that there had been centuries of peace. Then came the Dominators, and then a reference to a "Khund War" in living memory... the latter written by Jim Shooter.
* The ''ComicBook/MyLittlePonyFriendshipIsMagicIDW'' comics add a "[[http://mlp.wikia.com/wiki/File:Map-south_of_Equestria-scan-IDW_main_series_MLPFiM_comic_2.jpg South Equestria]]" region, which is where the Changelings re-established after their banishment from Canterlot.

[[folder:Fan Works]]
* ''Fanfic/WhatAboutWitchQueen'' adds Tampere Empire, Confederated Realms and Southernmost Lands to the map that so far contained only three city-states and the kingdom of Southern Isles. The latter gets to be described in more detail as well and at one point author gives a fairly clear (although only worded) world map.

[[folder:Films -- Live-Action]]
* Of course, ''Franchise/StarWars'' is the obvious example from Hollywood. The backstory of the Sith lords is the most {{egregious}} example, with numerous ExpandedUniverse novels putting it farther and farther into the Republic's 25,000+ year BackStory. It was eventually explained / retconned that the Sith the Jedi Council were talking about in ''Film/ThePhantomMenace'' were actually just one particular Sith Order, and that there have been dozens of different Sith Orders and Empires throughout history, and even a Sith ''species'' which is where they get their name from. They were eventually revealed to have first originated from a schism within the very first generation of the Jedi order.
* ''Film/TheMatrixReloaded''. The first Matrix film had a much smaller budget, with a relatively simple story. The second and third films had much larger budgets, with ''Anime/TheAnimatrix'' as reference material. As a result, there has been some debate as to whether or not the latter two films should be considered "true" sequels.

* ''Literature/TheLordOfOpium'': The original book, ''Literature/HouseOfTheScorpion'', mentioned that there were other drug dealers that started Opium, it never hinted or mentioned the Dope Confederacy, other nations that serve up drugs to everyone but the US and Aztlán. A major change to the universe is [[spoiler: how most of El Patron's workers were eejits, albeit high-functioning ones, which seems to contradict with remarks and statements made in the original book, that suggested only the farm laborers and a few others were the eeijts.]]
* As mentioned above, ''Literature/TheChroniclesOfNarnia'' books needed a lot of expansion to facilitate more stories. This caused plot inconsistencies, some of which were explained in the {{prequel}}, ''The Magician's Nephew''. The specific example in the intro may not be one, though: the prophecy is not "four humans", but "[[ExactWords two sons of Adam and two daughters of Eve]]," that is, two boys and two girls that are not native to Narnia or its neighbors. This one actually was explained in ''Prince Caspian''; the humans that founded those countries came over from Earth in the intervening centuries.
* ''Literature/TheWonderfulWizardOfOz'' had a similar expansion in its sequels. The Literature/LandOfOz was revealed to be surrounded by a vast desert with magical death-powers that separated it from other similarly fantastic realms. It was one of the few things in the Baum stories that actually retained consistency from one book to the next. And even here, it will only be consistent if we grant it a {{Retcon}}. In the first two books, it was implied that the deadly desert was separating Oz from the normal world full of {{Muggles}}, and not from other magical lands. ''Literature/{{Wicked}}'' attempts to justify this by placing Oz in an AlternateUniverse, which sometimes could catch dim glimpses of our own ("cities of smoke and glass").
* ''Literature/TheHobbit'' wasn't originally part of the same universe as ''Literature/TheSilmarillion'', which was written first despite being published later. The links were originally {{Shout Out}}s, but while the Hobbit's sequel, ''Literature/TheLordOfTheRings'', was being written, Tolkien decided to put both ''The Hobbit'' and its sequel into the Silmarillion's universe. In this process, inconsistencies were introduced; for instance, the One Ring seems a lot more innocent in ''The Hobbit''. Tolkien was at lest prudent enough to revise ''The Hobbit'' to clean up major inconsistencies -- and the "innocence" of the Ring is explained in ''The Lord of the Rings'' as [[UnreliableNarrator Bilbo not telling the whole story]] because of its evil effects.
* Throughout David Eddings's ''Literature/TheBelgariad'', the heroes stick primarily to the Aloria region of the world; countries like Cthol Murgos and Mallorea are only mentioned as where the opposing RedshirtArmy comes from. In the sequel series, ''Literature/TheMalloreon'', the quest sends the heroes into the aforementioned countries -- allowing Eddings the chance to lift the AlwaysChaoticEvil labels off of said country's inhabitants while he's at it. Then he did it ''again'' in ''The Elenium'' and ''The Tamuli''. In ''The Tamuli'', the official reason the main characters come up with for the trip to Tamuli is that, what with the old AlwaysChaoticEvil regime in the country in between them fallen, and travel and contact easier, it is now time to establish official relations. And ''The Belgariad'' not only mentioned Malloria, but actually went to it at the end of the first series, albeit only the extreme and virtually deserted northwest corner
* Even though the whole thing has been mapped, we've seen less than 50% of the ''Literature/{{Discworld}}'' up close. Creator/TerryPratchett initially said "There are no maps. You can't map a sense of humor", but later retracted said statement and commissioned official maps as the Discworld's setting was more firmly developed to respond more to the rules of plot than the RuleOfFunny. The statements are still reprinted in some editions of the Discworld books despite the fact that yes, there ''are'' maps. It's interesting that both the Anhk-Morpork and Discworld maps have tonnes of un-used locations that eventually show up -- for example, Borogrovia was first seen on the Map. Interestingly also, the first books DID talk about other worlds (such as the one of Tethys the Sea Troll), but these things haven't been really talked about since.
** The early books carried scraps of information and seemingly throwaway one-line-jokes suggesting there was an Australia-like country on the Discworld but it wasn't all that important for the plot of ''those'' books. Come Book Twenty-Two in the series and what do we get... ''[[Literature/TheLastContinent a Discworld Australia]]''. it has been noted that throughout the series there are lots of similar snippets and one-liners suggesting there is a Discworld "South Africa", which is yet to be properly explored. Alas. AuthorExistenceFailure intervened, but Crerator/TerryPratchett's personal assistant did note that at his death, one unfinished novel outline would have explored the Discworld Africa and its working title was ''The Dark Incontinent''. Snippets of Terry's ideas may have been released in the posthumously produced ''Complete Discworld Atlas''.
** A brief mention is made in ''Discworld/SmallGods'' of a tropical island ravaged by a tsunami and the need for the survivors to have to adapt to new circumstances. This is never explored in the Discworld but it's interesting to note Terry Pratchett later wrote a standalone novel, ''Literature/{{Nation}}'', which explored this very concept at some length.
* A number of ''Literature/{{Dragonlance}}'' novels pulled Expansion Pack Races. "Actually, there's also an entire underground kingdom of metal-working elves right beneath all the cities you know about!" Some of these would be integrated into the rest of the setting as it went forward, others would never be mentioned again outside of the book/series that particular author was working on. These races would tend to be "discovered" by the protagonist of the story that first featured them, helping to explain why we the reader haven't encountered them previously, but in at least one case (the FairFolk in the ''Defenders of Magic'' trilogy) very shortly after they're first discovered, other characters refer to them casually as if they've known about them all along.

[[folder:Live-Action TV]]
* The ''Series/StargateSG1'' series introduces a vast BackStory (and several thousand planets) not hinted at in the film. The creators of the film had their own backstory in mind, which was elaborated on in spin-off novels, but the series ignored it. Not to mention the fact that after the main immortal godlike alien bad guys of SG-1 got defeated, they decided to piss off immortal, godlike aliens from another galaxy, or that the spin-off series, ''Atlantis'', is set in a third, unique galaxy.
* ''Franchise/StarTrek'': Adding new planets and species to a space setting is normal. The problem comes when, for example, you introduce a species/planet and say it was already relevant.
** For example, the Cardassians in ''Series/StarTrekTheNextGeneration''. When they were introduced, the Federation was just supposed to have ended a war with them. A war that would have spanned the early seasons of the show and apparently was not an easy victory (it's repeatedly mentioned that they're "not ready for another war", though that might have something to do with a significant chunk of Starfleet getting blown up at Wolf 359 earlier that year as well, and they made concessions not consistent with an easy victory), yet was never mentioned and did not involve the flagship of the fleet (but ''did'' [[ContinuitySnarl involve the flagship's transporter chief, who was there from the first season]]).
** Then there are the Ferengi, [[EarlyInstallmentWeirdness who are introduced]] in ''Next Gen'' as a relatively newly-encountered and dangerous species, but by ''Series/StarTrekDeepSpaceNine'' are depicted as [[RetCon having been a major economic power in the quadrant for decades]].
** A worse example is ''[[Series/StarTrekEnterprise Enterprise]]''. At least three major species (Denobulans, Xindi, and Sulaban) are introduced in the expansion pack ''prequel''. Since they were never mentioned before, it means at least three species have vanished entirely from the galaxy. Of course, space is a big place, so it could be handwaved that they simply never came up on stories set in later years.
* The 1990's remake of ''Series/{{Land of the Lost|1991}}'' had better special effects than the original, but dumbed down a lot of the cool concepts of the original; in particular, it abandoned the idea of the Land being a closed universe which loops on itself (where if you run far enough in one direction, you wind up where you started). The second season, though, which was [[GrowingTheBeard markedly better written,]] took advantage of this difference by recognizing that the characters now had an entire ''planet'' to explore and didn't need to stay in the same place all the time.

[[folder:Tabletop Games]]
* ''TabletopGame/{{Warhammer 40000}}'' pulls these to add new races, especially with the Tau and Kroot. Of course, discovering new planets in a large universe is more believable than most of the examples that take place on a single world. Not to mention that sheer size of imperial databases makes it easy to forget about already discovered ones.
* ''TabletopGame/DungeonsAndDragons'':
** This was done EXTENSIVELY to the ''TabletopGame/ForgottenRealms'' campaign setting, adding entire new continents from out of nowhere, including Kara-Tur and the Utter East.
** Another example is Zakhara, the setting for the ''Al-Qadim'' game that was set in the same world as the Realms, and around about 1992 suddenly materialized to the south of both Faerun and Kara-Tur (and even connected to both by a land-bridge) despite never being referred to before; references to it became strangely fashionable after that point.
** Also, what was at least slightly more plausible, was introducing ''Maztica'', which was basically the Americas before Columbus, and not located on the same "supercontinent".
* ''TabletopGame/MagicTheGathering'' has an Expansion Pack Multiverse, where the characters visit a new world almost every year. Many earlier sets took place in Dominaria, a more traditional Expansion Pack World where previously unmentioned regions would suddenly appear in each new set.

[[folder:Video Games]]
* ''Franchise/TheLegendOfZelda'':
** ''VideoGame/ZeldaIITheAdventureOfLink'' series was set in ''North'' Hyrule, a region directly north of where the first game occurred. Death Mountain, located at the extreme north of the map in the first ''VideoGame/TheLegendOfZelda'', is now located at the extreme south, and two additional continents come into play.
** ''[[VideoGame/TheLegendOfZeldaOracleGames Oracle of Seasons and Oracle of Ages]]'' take place in Holodrum and Labrynna, countries bordering Hyrule.
** ''[[VideoGame/TheLegendOfZeldaLinksAwakening Link's Awakening]]'' takes place on Koholint Island [[spoiler: which turns out to be AllJustADream]].
** ''[[VideoGame/TheLegendOfZeldaPhantomHourglass Phantom Hourglass]]'' is in some other region of the Great Sea we saw in its predecessor, ''[[VideoGame/TheLegendOfZeldaTheWindWaker Wind Waker]]'' [[spoiler: that is also a parallel world]].
** ''[[VideoGame/TheLegendOfZeldaSpiritTracks Spirit Tracks]]'' takes place in a totally new Hyrule founded by the ''Wind Waker''/''Phantom Hourglass'' Link and Zelda (aka Tetra) about a hundred years after its foundation.
** ''[[VideoGame/TheLegendOfZeldaTwilightPrincess Twilight Princess]]'' adds a parallel world of twilight, [[note]]not to be confused with the Dark World from ''VideoGame/TheLegendOfZeldaALinkToThePast''[[/note]], connected to Hyrule only by a mirror, [[note]][[SincerityMode also nothing like]] ''A Link to the Past'' either[[/note]] which has an otherworldly glow to it filled with [[spoiler:the shadowy descendants of dark wizards trapped by the Goddesses. They were the creators of the first set of PlotCoupons in the game, the Fused Shadows]]. It's also the home of Midna and [[spoiler:Zant]]. Oh, and Hyrule has an icy peak in this game. Wait, what?
** ''[[VideoGame/TheLegendOfZeldaMajorasMask Majora's Mask]]'' is set in Termina, a land in a parallel world to Hyrule with [[strike:character models taken from ''VideoGame/TheLegendOfZeldaOcarinaOfTime'']] alternate versions of familiar secondary and tertiary characters. The series seems to love alternate universes; no wonder Hyrule could be said to be a PlanetEngland.
** [[SubvertedTrope Subverted]] in ''[[VideoGame/TheLegendOfZeldaALinkBetweenWorlds A Link Between Worlds]]''. The game starts in the Hyrule of ''A Link to the Past'', and the map is an almost one-to-one recreation. And then the player is plunged into Lorule, yet another Alternate Hyrule that is not to confused with the Dark World in Link to the Past despite looking practically identical.
** [[https://www.youtube.com/watch?v=jM-KljboL7Y&feature=iv&src_vid=rTT91ywkSaA&annotation_id=annotation_2230058621 Preliminary analysis]] of the map in ''Zelda Wii U'' implies that the game will try to consolidate the maps of Zelda I and II, Ocarina, and Twilight Princess.
* ''VideoGame/{{Fallout}}'':
** ''VideoGame/{{Fallout 2}}'' takes place to the north of the events of the previous game. The most northern (AND most significant) locations in the previous game are relegated to {{Bonus Dungeon}}s at the southern end of the map.
** ''VideoGame/{{Fallout 3}}'' takes place on the east coast, around DC in a region called ''"The Capital Wasteland"''.
** ''Fallout 3's'' DLC ''Operation Anchorage'' places the player in a simulation of a battle between the US Army and Communist Chinese in Alaska, and ''The Pitt'' allows the player to visit the remnants of Pittsburgh. ''Broken Steel'' adds a small area south west of DC, and Adams Air Force Base. ''Point Lookout'' adds a new, swampy portion on the Maryland coast, and ''Mothership Zeta'' is set on an alien spaceship.
** ''VideoGame/FalloutNewVegas'' runs on the same engine as ''3'', but is set in the area of Las Vegas, near where the first two games took place. It's been referred to - often favorably - as like a huge expansion to ''3''.
** ''New Vegas'''s DLC ''Dead Money'' takes place at the Sierra Madre casino and the villa surrounding it. ''Honest Hearts'' is set in Zion National Park in Utah while ''Old World Blues'' takes place in a crater (former mountain)/old world research facility known as the Big MT. The final DLC, ''Lonesome Road'', takes place in an area known as the Divide, which was apparently the site of a old world missile base and the town that sprang up around it that was torn asunder by a cataclysmic event in the Courier's past.
* In the sequels to the ''Franchise/{{Pokemon}}'' games, it's revealed that ''VideoGame/PokemonRedAndBlue'' took place in the region of Kanto, which is just one region within a larger nation. ''VideoGame/PokemonGoldAndSilver'' takes place in the region of Johto, just to the west. ''VideoGame/PokemonRubyAndSapphire'' takes place on Hoenn, an island far to the south, and ''VideoGame/PokemonDiamondAndPearl'' on Sinnoh, far to the north - but they are all encapsulated within [[http://bulbapedia.bulbagarden.net/wiki/Pok%C3%A9mon_nation the same country]], a [[FantasyCounterpartCulture thinly-veiled approximation of Japan]]. ''VideoGame/PokemonColosseum'', meanwhile, takes place in a different area (Orre), and its sequel, ''VideoGame/PokemonXDGaleOfDarkness'', adds a new section to the northwest of the region, while keeping most of the original game's locations. ''XD'' also adds a seaport, despite the map of Orre in ''Colosseum'' depicting Orre as being landlocked.
** This hasn't created ''that'' many inconsistencies, except we're supposed to believe that every three or so years about a hundred "new" Pokémon suddenly arrive to start having always existed. ''Ruby'' and ''Sapphire'' are implied to take place at the same time as ''Red'' and ''Blue'' too, which raises further questions, especially in the [[VideoGameRemake remakes]] of the first two games, where the game is restricted to the original 151 Pokémon until the player beats the Elite Four and gains the National Pokédex, at which point the next 235 of them from the second and third generations suddenly come out of the woodwork with no comment or explanation. Also, the rank of Pokémon League Champion in the first games is supposed to be the title of the world's strongest trainer. Then we find out that it's a regional competition. Not international. Not even ''national''. Quite overblown to say being the best Pokémon trainer in a country's single province equates with being the world's best... It's implied in ''Omega Ruby and Alpha Sapphire'' that the reason for the inconsistencies is because some of the games depict events within [[AlternateUniverse multiple realities]].
** Also, a few regions aren't sure to fit within the country of Gens I-IV - it helps that they're based on [[VideoGame/PokemonColosseum Arizona]], [[VideoGame/PokemonBlackAndWhite New York]], [[VideoGame/PokemonXAndY France]] and [[VideoGame/PokemonSunAndMoon Hawaii]] in contrast to the Japanese inspiration of the others.
** In ''VideoGame/PokemonBlack2AndWhite2'', a good few new areas were created, which had supposedly been there the whole time. Also, one place had a rockslide all over it since the last game.
* ''Franchise/TheElderScrolls'':
** A literal expansion pack world occurred in ''[[VideoGame/TheElderScrollsIVOblivion Oblivion]]'': the expansion pack ''Shivering Isles'' takes place in the domain of a god of madness, which is almost completely disconnected from the original world. The link is a portal on an island that magically appears in the middle of lake. The game even [[LampshadeHanging lampshades]] the island's sudden appearance.
** ''[[VideoGame/TheElderScrollsIIIMorrowind Morrowind]]'' has the island of Solstheim, which is notable for allowing [[VideoGame/TheElderScrollsVSkyrim the fifth game]] to avert this by using the same island again, albeit very different from its first appearance.
* ''VideoGame/DragonQuestII'' reveals that the country of Alefgard is just a small part of the planet. The [[VideoGame/DragonQuestIII third game]] returns to Alefgard being the entire world available again, even if you travel around it in a boat. [[spoiler: Though, of course, this could be justified by it being sealed away... ''and'' it's not the world you start out on.]]
* In a reversal, ''VideoGame/UltimaI'' had 4 continents, but became one continent with ''VideoGame/UltimaIII''. Much {{retcon}}ning was done to explain this in the later games, with at least one continent still unaccounted for.
* The first ''VideoGame/{{Warcraft}}'' game was set on a single continent, home to the kingdom of Azeroth and featured humans and orcs as the only intelligent races. Its sequels added three additional continents (and expanded the original greatly), four other inhabited planets, and no less than two dozen additional races; additionally, the name "Azeroth" somehow came to apply to the entire planet rather than the human kingdom, which was [[RetCon retroactively]] renamed "Stormwind".
** ''[[VideoGame/{{Warcraft}} Warcraft II]]'': In the first game, we had the one Kingdom, Azeroth. The second game expanded the word "Azeroth" to the entire original continent, which included a region called Khaz Modan, and revealed there was also another continent named Lordaeron to the north of Azeroth. Draenor (later, Outland), the orc homeland, is a debatable example as it was mentioned (not by name) in Warcraft I, but details were scant and irrelevant at the time.
** ''[[VideoGame/{{Warcraft}} Warcraft III]]'': Northrend is a fairly straight example, being a northerly continent that is implied to be a well known, if mostly inhospitable, continent despite not existing before. Kalimdor is also a straight example, being a continent comparable to Azeroth, Khaz Modan, and Lordaeron combined that is established to have been extremely important to the history of the world (and shared its name with a Pangaea-like original continent), but its existence being lost to history (and the existence of everything else being assumed lost to the natives) was a plot point.
** ''VideoGame/WorldOfWarcraft'', despite literally adding a new world or continent in each expansion pack (and providing a good page image), [[AvertedTrope averts]] this. It ascribes to the rule that if you can't go there yourself, it's not on the map, since that would make your map a bit confusing, so it appears as if this is happening, but all locations have pre-existed in some form. The first two expansions brought back Outland and Northrend, the third expansion pack filled out inaccessible (but clearly existent) regions and the elemental planes that had been elaborated on in TabletopGame/WarcraftTheRoleplayingGame. The fourth expansion pack brought us to Pandaria, which had not been accessible in any previous game, but was implied in Warcraft III and elaborated on in the aforementioned RPG. The fifth expansion sees an alternate timeline of the long-established Draenor, and the sixth expansion pack goes to the Broken Isles first established in Warcraft II.
* ''VideoGame/EverQuest'' loves this trope. The game originally had three continents: Antonica, the main continent. Faydwer, to the east, which had the elven, dwarven and gnome homelands. Odus, a tiny island where a human subrace hailed from. Then the first expansion introduced Kunark, a {{LostWorld}} full of ancient ruins and deadly lizards. The second expansion added Velious, a frozen northern waste with powerful dragons and giants and more dwarves. Most expansions have added a new continent, sets of planes of existence, or vast new stretches to existing continents.
* Each successive game in the ''VideoGame/{{Suikoden}}'' series took place in a different region of the world. Averted though in that all these regions, and some bits of their culture, were already mentioned to have existed. Also, some of the events that are set in another region (and another game) are also referenced before the player even plays them, [[spoiler:such as Georg Prime's killing of Queen Arshtat, first mentioned in ''[[VideoGame/SuikodenII II]]'' and occurred in ''[[VideoGame/SuikodenV V]]'' (due to AnachronicOrder of the games)]].
* The Squaresoft realm of Ivalice was well prepared for this. In ''VideoGame/FinalFantasyTactics'' the game focused on one country in civil war. ''Vagrant Story'' included {{Shout Out}}s to ''Tactics'', and then ''VideoGame/FinalFantasyXII'' showed Ivalice to also be a region of the world in which the former stories were located. Despite all of this, the world (and the Ivalice region, for that matter) has yet to be seen in its entirety, and ''FFXII'' goes to great lengths in mentioning other lands and countries beyond the borders of the game's map. This all worked rather well, geographically speaking. However, the timeline seemed to mystify, at least until the WordOfGod made itself heard. This was further muddled by ''VideoGame/FinalFantasyTacticsAdvance'', which featured Ivalice as part of a TrappedInAnotherWorld plot based in a ''fictional version'' of Ivalice. Its sequel looks set to go even further, transporting its character into Ivalice proper (and therefore expanding true Ivalice yet again).
** The first expansion of ''VideoGame/FinalFantasyXI'' introduced the HiddenElfVillage hometown/island of the [[CatGirl Mithra]] and the third expansion pack introduced a whole foreign ''continent'' that had somehow been missed up to this point. There's also the [[ForWantOfANail parallel world]] of Dynamis. The fourth expansion pack used TimeTravel to introduce new areas without actually changing the world, by allowing players to travel back in time to the age of the Crystal War and experience key events of the war.
*** That's not even the end of it, there are many more areas in the world that various npc's and item descriptions mention including: The southern continent (where mithra really come from), the far west (which seems to have a culture similar to that of native Americans), the other half of the near east (adventurers aren't allowed to enter the eastern half of Aht Urghan making it impossible to get to any part of the continent that is east of the city), and the far east (the DoomedHometown of an important npc). Suffice it to say that SE won't run out of expansion fodder anytime soon.
* ''VideoGame/ChronoCross'' takes place mostly on the El Nido Archipelago, a group of small islands off the coast of Porre, in the same world as ''VideoGame/ChronoTrigger''. The archipelago is not visible in ''Chrono Trigger'' (although its OverworldNotToScale is amazingly simplified, with all of four towns visible on the ''planet''). To be fair, the archipelago didn't actually exist in ''Chrono Trigger'', as [[spoiler:a future civilization that found itself in the distant past as a side-effect of the events of the first game {{terraform}}ed the islands]].
* Lampshaded in ''Puzzle Quest: Challenge Of The Warlords'', where realms ruled by Bane and Sartek's fellow Horsemen (Band and Sartek are Death and War, respectively) are explicitly mentioned, as well as other elf kingdoms. Being based on the pre-existing ''Warlords'' series, which had four games and three spinoffs prior to this, so they didn't have a shortage of locations.
* In ''VideoGame/BanjoKazooie'', aside of the nine worlds that the game lets you explore, the game takes place at Spiral Mountain, which is also home to Gruntilda's Lair. Then in ''Banjo-Tooie'', a digger tunnel was created, expanding the world into the Isle o' Hags, and every main world, unlike the original game and apart from the sky level, is explicitly a [[PatchworkMap region of the overworld]]. In ''Banjo-Kazooie: Nuts & Bolts'', the Isle o' Hags is once again limited to Spiral Mountain, but the majority of the game takes place in the new Showdown Town and the game-worlds created by the Lord Of Games.
* The ''VideoGame/AceCombat'' series almost does this in reverse - the ''geography'' of the world was revealed early on and has remained relatively consistent, but until the ''fifth'' game only one continent, Usea, was actually used, with each new installment simply filling in the blanks. As of ''VideoGame/AceCombat6FiresOfLiberation'', one of only three games to take place on a different continent (and the only one for the continent in question, at that) there are still a few countries that haven't even been named, and many more that we know very little about.
* ''VideoGame/CityOfHeroes'':
** The Rogue Isles were added in the 'exphanshalone' pack ''VideoGame/CityOfVillains'', as a bunch of fictional Caribbean islands. Both cities were eventually consolidated into a single game (granting anyone who purchased one complete access to the other.)
** The second expansion, ''Going Rogue'', adds Praetoria, a {{Dystopia}}n MirrorUniverse of the main game world rife with GreyAndGreyMorality. Unlike ''City of Villains'', ''Going Rogue'' cannot be played on it's own. Praetorian content only goes up to level 20. The real star of ''Going Rogue'' is the Alignment System, which essentially turns Paragon and the Rogue Isles into Expansion Pack Worlds for each other.
* ''VideoGame/EveOnline'' added around 2000 star systems in the Apocrypha expansion. The in-universe explanation is a NegativeSpaceWedgie that caused wormholes (that lead into the new systems) to appear all around the galaxy.
* ''VideoGame/{{Touhou}}'':
** Generally speaking, each new main game of the series has introduced a new area. ''Mountain of Faith'' is a partial exception, though; Youkai Mountain had been a (single) stage in the previous game and detailed in [[AllThereInTheManual a databook]], but had yet to get any plot focus.
** ''Undefined Fantastic Object'' is weird here; a third of the game is set in the new area of Makai... which we learn nothing about and are unlikely to ever see again. The real expansion to the world is the temple built in the ending.
** ''Ten Desires'' gives the bosses a fancy mausoleum as their headquarters... which they promptly desert after the main story.
* ''VideoGame/GuildWars'' added new continents, Cantha and Elona, for its second and third campaigns[[note]]these were foreshadowed in the first game, and players could see Elona, if they knew where to go[[/note]]. The fourth instead expanded the original continent.
* The ''SuperMarioBros'' games, as well as all the RPG spinoffs, at least when it doesn't just [[ChaosArchitecture seem to rebuild the entire Mushroom Kingdom from scratch]], like to suddenly reveal all new countries just across the border from the main area, such as the lands of ''VideoGame/SuperMarioBros3'' and ''VideoGame/SuperMarioWorld'', Sarasa Land from ''VideoGame/SuperMarioLand'', Mario's own (unexplained in subsequent games) kingdom in ''Super Mario Land 2'', Beanbean Kingdom from ''VideoGame/MarioAndLuigi'' and Rogueport and the surrounding areas (plus the offscreen adventures of Luigi in the Waffle Kingdom and nearby lands) from ''VideoGame/PaperMarioTheThousandYearDoor''. However, Isle Delfino from ''VideoGame/SuperMarioSunshine'' is a plane journey away, so it's presumably not "the next land over", and the ''VideoGame/SuperMarioGalaxy'' games? ExactlyWhatItSaysOnTheTin. The final boss of ''Super Mario Galaxy'' is even fought at the centre of the universe.
* Happens with the ''VideoGame/DungeonSiege'' ExpansionPack Legends of Aranna: The entirety of the expansion pack occurs in a part of Ehb that had not been known about, and features a race thought to be long dead in the multiplayer campaign. Less so with the sequel, ''Dungeon Siege II'', as the original stated that Ehb was formed by the Tenth Legion as they fled the collapse of the Empire of Stars. Subverted in DSII: Broken World as [[spoiler: the Second Great Cataclysm at the end of ''DSII'' caused massive changes to the land allowing the overall layout to remain the same while still adding new areas to explore.]]
* ''VideoGame/{{Majesty}}'' plays this so straight it's almost a LampshadeHanging with the aptly-named ''Northern Expansion'' ExpansionPack, which reveals a previously inaccessible northern half of the world map. Possibly a subversion, as it's visibly the same world map graphic save for the fact you can now scroll north of the mountain range in the middle of the continent; it's possible that some of the new quests were intended for the original game but cut for time or disk-space reasons.
* ''VideoGame/DragonAgeII'' takes place in the city of Kirkwall, nearby Sundermount and the Wounded Coast. ''Legacy'' expands on this with Hawke travelling to a Grey Warden fortress in the Vimmark Mountains, while ''Mark of the Assassin'' has Hawke take part in a heist at Chateau-Haine, near the border with Nevarra.
* While it was clear from the start that there were other ''worlds'' (it ''was'' [[MorePopularSpinoff a spinoff]], after all), VideoGame/HeroesOfMightAndMagic started out with a single continent, Enroth, and then added another continent in the third game. Then the eight game in the VideoGame/MightAndMagic series took place on another previously unmentioned continent on the same world (although one of the ''regions'' of the continent had been mentioned before).
* In ''VideoGame/FireEmblem'', a new continent and conflicts are established every one or two games.
* In the ''Franchise/{{Ys}}'' series, Adol always go on a new adventure on a new continent.
* [[ZigZaggingTrope Zig-zagged]] in ''Franchise/SilentHill''. [[VideoGame/SilentHill1 The first game]] is set in the eponymous town's northern region, which is revisited in ''[[VideoGame/SilentHillOrigins Origins]]'' and ''[[VideoGame/SilentHillHomecoming Homecoming]]'' (albeit partly in new areas that were unseen in ''1''). ''VideoGame/SilentHill2'' moves the action to the town's southern half, as well as one part of the north that was unexplored in ''1''; ''VideoGame/SilentHill3'' revisits this southern half, along with the amusement park from ''1''. ''[[VideoGame/SilentHillDownpour Downpour]]'' moves yet again to the heretofore unmentioned southeastern region. Meanwhile, ''VideoGame/SilentHill4'' takes place in a different town entirely, although the protagonist does visit Otherworldly recreations of Silent Hill. And ''[[VideoGame/SilentHillShatteredMemories Shattered Memories]]'' takes place in an outright AlternateUniverse.
* ''VideoGame/FinalFantasyXIV'' is all over the place with the trope before and after 2.0 when the game was remade:
** The Coerthas region has several areas that were mostly mountainsides and large rolling lush green hills, but after the Calamity happened, the landscape was changed in such a short amount of time that all of Coerthas became a near barren frozen wasteland. Only the Central Coerthas Highlands were accessible to players while the other parts were sealed off with in-game lore explaining that the other areas were either too devastated to travel safely or there was simply no way to get to those areas. The ''Heavensward'' expansion pack reopened the Coerthas Western Highlands which retains most of the physical geography, but just like all the surrounding areas, it's all frozen over. Similarly, other areas like the Black Shroud and Thanalan underwent redesigns post Calamity by either sealing off areas (as was the case for the West Shroud) or making it where a GravityBarrier would prevent players from going to the old areas, though this was mostly done to condense the maps since one of the major flaws of 1.0 was tons of CutAndPasteEnvironments. In a way, the reduced amount of areas is an inverse of the trope where the new story reduced the world rather than expand it.
** Ishgard is a nation to the far north of Eorzea (a land mass where the whole game takes place on) that could be seen from the Coerthas Central Highlands since 1.0, but it wasn't accessible due to the nation closing its gates to foreigners while it dealt with the war on dragons. It wasn't until the ''Heavensward'' expansion where players were able to access the city of Ishgard for the first time and explore the lands beyond it.
** The ''Stormblood'' expansion pack introduced two areas: the region of Gyr Abania, located to the east of Eorzea and home to the nation of Ala Mhigo, and Othard, a continent located to the FarEast of Eorzea, and home to the nation of Doma.
* The first ''VideoGame/LittleBigPlanet'' game made it clear there were only 8 Creators in Craftworld, corresponding to the 8 worlds in the game. Then [=LittleBigPlanet=] 2, [=LittleBigPlanet=] PSP and [=LittleBigPlanet=] Karting added a double digits number of new worlds, followed by [=LittleBigPlanet=] PS Vita and [=LittleBigPlanet=] 3 adding in two entirely new planets named Carnivalia and Bunkum (respectively) out of nowhere.
* ''VideoGame/SuperMetroid'' has Samus return to Zebes from [[VideoGame/Metroid1 the first game]], and apparently there was a whole underground jungle region of Brinstar lying just to the left of the rocky blue Brinstar she originally explored. Likewise, there's Crateria, the Wrecked Ship and Maridia, all of which had no sign of existing in the original (except maybe the title screen in the former's case). The original game's remake, ''VideoGame/MetroidZeroMission'', curiously added Crateria, but left out the jungle part of Brinstar, Maridia, and the Wrecked Ship (save for a few rooms that slightly resemble it).[[labelnote:*]]While the Space Pirate Mother Ship would seem to be the future Wrecked Ship, WordOfGod is that the two are different.[[/labelnote]] It also added Chozodia, a region Samus apparently never bothered to go to in either ''Super Metroid'' or the original.
* The ''VideoGame/MafiaIII'' DLC "Faster, Baby!" adds Sinclair Parish, Louisiana, a [[DeepSouth small Southern town]] west of [[TheBigEasy New Bordeaux]] where you battle [[TheKlan local white supremacists]] fighting tooth and nail against [[UsefulNotes/CivilRightsMovement integration and civil rights]].
* The ''[[VideoGame/KisekiSeries Trails'']] series like ''Suikoden'' above goes to great lengths to avert this. The [[VideoGame/TheLegendOfHeroesTrailsInTheSky first series]] takes place in Liberl, a small kingdom that borders the empire of Erebonia and the Republic of Calvard. While we don't see Erebonia in person until the [[VideoGame/TheLegendOfHeroesTrailsOfColdSteel third series]], it's completely justified as the ''Sky'' games take place a decade after the war between the two countries still weighs heavily on local politics and the border security naturally isn't keen on you trying to cross. Nevertheless, we do learn several things about it in the meantime, including the names of several important locations, the state of its politics, and several characters hail from there. In fact, we learn about the BigBad of those particular games and his goals [[TheProducerThinksOfEverything 7 years before the game that introduces him came out]]. Meanwhile, there's [[VideoGame/ZeroNoKiseki Crossbell]], the city-state some ways away from Liberl we see glimpses of in a flashback before the second series would explore it. The series' consistency is such that the likely plot points explored in the Calvard Arc can be deduced before the next series has been announced (as of the current edit).
