A common way to name movie {{sequel}}s is to take the title of the original, possibly abbreviated, and add a number. So ''Foomovie'' will be followed with ''Foomovie 2'', ''Foomovie 3'' (or ''[[ThirdIs3D 3D]]''), etc. Also common is to follow ''Foomovie'' with ''Foomovie, Part 2'', etc. - though the word "part" will usually be dropped when talking about the movies. (This is usually done when the stories of the movies are supposed to form one big story.) Sometimes there are subtitles as well.

The result of this is that the original ''Foomovie'' will become known as ''Foomovie 1'', and on occasion will actually be rereleased this way (see {{Retronym}}). This is actually a recent practice, beginning in the 1970s.

If the movies in a series were made out of chronological order, the numbering can refer either to the order in which they were made or the order in which they take place. The latter gets you titles like ''VideoGame/ResidentEvil0'' and ''Disney/TheLionKingOneAndAHalf''. Very rarely, you'll see a prequel with a negative number. The print version of the webcomic ''[[Webcomic/TheOrderOfTheStick Order of the Stick]]'' has two prequels, numbered #0 and #-1, and the French comic ''Donjon'' (planned to run from #1-#100) has spinoff series planned to run from #-99 to #0 and #101 to #200.

Some series use Arabic numerals, some use Roman numerals, and some use either. The distinction between Roman numerals and Arabic seems to be the distinction between grand-scale affairs that take themselves very seriously (and thus borrow a bit of grandeur from the western world's most prominent VestigialEmpire), and stories that either don't take themselves entirely seriously, or have a futuristic bent that makes the Arabic numerals look all sciency and mathematical.

This trope [[StoppedNumberingSequels can be subverted]]: The ''VideoGame/{{Marathon}}'' series started with ''Marathon'' and ''Marathon 2'' but then jumped to ''Marathon '''Infinity'''''. The subsequent release and open-source development of ''Marathon 2'''s game engine restored sequential numbering by naming the engine ''Aleph One'', [[UpToEleven the next largest infinity]]. (See below.)

In the Horror genre, a sixth installment may be called [[NumberOfTheBeast 666]] (Or sometimes called that even if it isn't the 6th) it will almost always be pronounced "six-six-six" rather than "six hundred and sixty-six".

This is, if anything, even more common in video games than in movies, although the "Part 2" variation is absent there. Literary examples, on the other hand, are very, very rare.

The first use of a number without "part" was probably ''Quatermass 2'' in 1957, the follow-up to ''The Quatermass Xperiment''. These were the original UK titles; in the United States the first film was issued as ''The Creeping Unknown'' so the second one had to be retitled as well: it was known as ''Enemy From Space''. However such instances were rare, at least before the 70s because studios at the time felt that it attached a film to an earlier film to the extent of alienating potential audiences who may not have seen the earlier film and so feel discouraged from seeing a sequel titled "Part II" if they had not seen "Part I". It's why all the Film/JamesBond films were titled differently and not James Bond 1-20, and why film-series such as the "Carry On" or the Pink Panther series often included "Pink Panther" but slight variations so as to not tie it exclusively. The first major film to change this was Creator/FrancisFordCoppola's ''Film/TheGodfather''.

For some reason (FourIsDeath? RuleOfThree?), it's very common for Numbered Sequels to stop at 3, and any subsequent media to be given a subtitle alone instead.

Parodies take this to extremes with RidiculousFutureSequelisation.

[[folder:Anime & Manga]]
* ''Anime/{{Macross 7}}'' is not the seventh ''Anime/{{Macross}}'' series -- it's the third in the official continuity, after ''Anime/SuperDimensionFortressMacross'' and ''Anime/MacrossPlus''. Confusingly, a different production group created an unofficial sequel called ''Anime/MacrossII''. It wasn't well received. The prequel series ''Anime/MacrossZero'' really does come first chronologically.
* Not a movie series, but deserving of mention, are the cyborgs of ''Manga/{{Cyborg 009}}''. The protagonists are [[HollywoodCyborg cyborgs]] designated [=001-009=]. But the one that follows 009 ("zero zero nine") is named ''0010'' ("zero zero ten"), rather than the logical 010. The series also does this with [[spoiler:all subsequent cyborg characters.]]
* ''Anime/DigimonAdventure02'' looks like this, as it ''is'' after all the second ''Franchise/{{Digimon}}'' series, but the number actually derives from its status as being [[TwentyMinutesIntoTheFuture set in the year 2002]]. One could assume the number doubles as this.

[[folder:Comic Books]]
* ''ComicBook/OneHundredBullets'' has an interesting twist on this- every story arc/trade paperback has a title that either incorporates its number into it (eg- book 4 is ''A Foregone Tomorrow'', book 9 is ''Strychnine Lives'') or uses part of a known phrase that includes the number, but leaving the actual number out (eg- book 7 is ''[[Film/SevenSamurai Samurai]]'' and book 12 is ''[[Film/TheDirtyDozen Dirty]]'')
* ''ComicBook/TheUltimates 2'' and 3.

[[folder:Fan Works]]
* Examples from Fanfic/{{the Calvinverse}}:
** ''Fanfic/CalvinAndHobbesIILostAtSea'' and ''Fanfic/CalvinAndHobbesIIIDoubleTrouble''.
** Zig-zagged with ''Fanfic/RetroChill'' - the fic itself doesn't mention a number, but other sources refer to it as "Calvin and Hobbes IV: Retro Chill".
** From ''Fanfic/CalvinAndHobbesTheSeries'':
*** InUniverse, we have "Tornado Sharks 2: I Think Things Just Got A Little More Windier".
*** In the story itself, there's "The Night of the Living Television II" and more subtly "Part Three", as well as "Mirror rorriM" and "Mirror rorriM Two".

[[folder:Films -- Animated]]
* The ''Anime/{{Pokemon}}'' movies go like this: "Pokémon: The First Movie", "Pokémon The Movie 2000", "Pokémon 3 The Movie", "Pokémon 4Ever", and then they stop trying to incorporate the numbers into the title and just go to straight subtitles.
** Made absolutely ridiculous by the fact that the subtitle of "The First Movie" is "Mewtwo Strikes Back", clearly implying that it was a sequel. (This had long been what we Americans had been told, but it turns out that this is not totally true, as ''The Origin of Mewtwo'' was just a short featurette of the same length as those ubiquitous Pikachu specials.) The origin story, which had been removed from the American theatrical release of ''Pokemon: The First Movie'' in order to preserve the G rating, was eventually packaged on the direct-to-video release Mewtwo Returns. So we have a "Strikes Back", and then we have a "Returns". Is anyone else sensing a ''Franchise/StarWars'' {{Homage}} here?
* The ''WesternAnimation/{{Shrek}}'' films seem to be using the same system as ''Series/BlackAdder'' as an {{Homage}}: ''Shrek'', ''WesternAnimation/{{Shrek 2}}'', ''WesternAnimation/ShrekTheThird'', and ''WesternAnimation/ShrekForeverAfter''.
** They were supposedly reluctant to use the title "Shrek 3," lest it create confusion with the short "Shrek 3-D" which was released in a box set with the first two films.
* Wanna hear something funny? ''WesternAnimation/TheLandBeforeTime'' started to number its sequels with Roman numerals, and to this day never changed that formula. [[http://en.wikipedia.org/wiki/The_Land_Before_Time_%28series%29 We're talking about ''thirteen'' movies, by the way.]]
** Of course, after reaching double-digits the movies started to go out of their away to avoid mentioning what number they were up to, as if out of embarrassment. Re-releases of the sequels on DVD rarely state the number of the movie anymore either.
* The WorkingTitle of ''WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks'' was ''Equestria Girls 2''. This title is still used in advertisements and [=DVRs=] in some countries.

[[folder:Films -- Live-Action]]
* ''Film/TheGodfather'':
** The first major film to start using this Shakespearian title technique was ''Film/TheGodfatherPartII''. It was one of Francis Ford Coppola's three demands for working on the sequel. His two other demands were approved, but the studio highly objected to simply following the title with a number. Its success began the tradition of numbered sequels.
** Oddly, enough, this was [[InvertedTrope inverted]] for ''Film/TheGodfatherPartIII''. Coppola wanted to call it ''The Death of Michael Corleone'' but the studio wouldn't let him. Coppola's reasoning is that the first two Godfather films necessarily covered a single extended story and made at a short interval with the same cast. ''Part II'' carried forward the dramatic currents of the first film whereas ''Part III'' was essentially a DistantFinale and epilogue, and largely self-contained.
* Before the Godfather there had already been the Kraut Westerns ''Film/WinnetouI'', ''Winnetou II'', and ''Winnetou III'' (1963-1965), although these were named after the books they were based on. Although these examples of the highly successful Karl May franchise did not sell that well outside Germany, they were taken notice of in America because they showed that the Western genre was not dead yet.
* The UrExample is probably Creator/SergeiEisenstein's ''Film/IvanTheTerrible'', which was released in two parts in 1944 and 1958. Coppola himself cited Eisenstein when arguing for ''Film/TheGodfatherPartII''; the studio dismissed this argument on the grounds that ''Ivan'' was a Russian film, and no one had seen it.
* The ''Franchise/{{Rocky}}'' series followed this trope until the sixth installment which was called ''Film/RockyBalboa'' (as if the other movies were about some other guy named "Rocky"). Word of God says that the movie was not called "Rocky VI" to avoid any possibility of another ''Rocky'' installment.
* Parodied by ''Film/TheNakedGun'' series; ''The Naked Gun'' was followed by ''The Naked Gun 2½'' and ''The Naked Gun 33⅓'' (33⅓ is the speed one plays an LP). Another sequel, provisionally titled ''The Naked Gun 444.4'' or ''The Naked Gun 4 Score and 3 Sequels Ago'' was in development in the late '90s, although obviously nothing came of it.
* ZAZ didn't want to have anything to do with ''Film/AirplaneIITheSequel'', (and even claim to this day to have never watched it), even though they'd later make sequels to ''Film/TheNakedGun'' and ''Film/HotShots''. ''Airplane II'' lampshades the trope with the announcement at the end of the credits "Coming soon from Paramount Pictures : ''Airplane III''" followed by William Shatner saying "Wait! That's exactly what they'll be expecting us to do!"
* The sequel to ''Film/HotShots'' was ''Film/HotShotsPartDeux'' ("deux" is French for "two"), with the tagline, "Just [[{{Pun}} Deux]] It!"
* The ''Film/OceansEleven'' remake proved popular enough to warrant a couple of sequels. Instead of using the rather cumbersome ''Ocean's Eleven Two'' or somesuch, the makers dubbed the sequels ''Film/OceansTwelve'' and ''Film/OceansThirteen''. This led to many jokes about where the first 10 movies went. And the titles end up being spot-on with the number of people involved in the main heist (12 adds Ocean's wife, 13 adds [[EnemyMine the antagonist of the other movies]] and a technical expert).
* Likewise, the second live-action ''Film/OneHundredAndOneDalmatians'' film was titled ''Film/OneHundredAndTwoDalmatians''. Although there was a straight-to-video follow-up to the original animated film (42 years later!) called ''Disney/OneHundredAndOneDalmatiansIIPatchsLondonAdventure''.
* Many ''Franchise/StarWars'' fans were rather confused when the 1977 original, simply titled ''Star Wars'', was followed by Episode '''Five''', ''Film/TheEmpireStrikesBack''. A rerelease of the original rechristened it "Episode Four: Film/ANewHope", paving the way for later prequels. Despite the initial confusion, there was a level of optimism that resulted from the episode numbering system that opened the door for prequels. In the meantime, the Classic Trilogy continued to be marketed by the movies' original release names: ''Star Wars'', ''Film/TheEmpireStrikesBack'', and ''Film/ReturnOfTheJedi'', with the episode numbers confined strictly to the opening crawls. ''Film/ThePhantomMenace'' began the trend of prominently featuring the episode number in marketing the movies, to the point where theaters often listed it as "Star Wars Episode I" rather than "The Phantom Menace". When the Classic Trilogy received its first DVD release in 2004, the movies were now labeled ''Star Wars: Episode IV: A New Hope'', etc.
** The first film of the sequel trilogy was marketed simply as ''Star Wars: The Force Awakens'', in contrast to the prequel films. Unlike the prequels, this is also its official title although it is still called ''Star Wars: Episode VII:'' ''Film/TheForceAwakens'' in its opening crawl. Likewise for the next film, ''Film/TheLastJedi Star Wars: The Last Jedi''.
* For its European release, Italian director Creator/LucioFulci heavily re-cut Creator/GeorgeARomero's ''Film/DawnOfTheDead1978'' to produce what was essentially a completely different movie, which he titled ''Film/{{Zombi}}''. After its success, Fulci went on to produce five sequels, which were titled ''Film/{{Zombi 2}}'', ''Film/{{Zombi 3|D}}'', and so forth. ''Zombi 2'' was simply retitled ''Zombie'' for its North American release, but the later sequels shared their numbering on both sides of the pond - meaning that while you can find ''Zombie'', ''Zombie 3'', and ''Zombie 4'' at your local video rental outlet, there is no movie available in North America titled ''Zombie 2''.
** No longer true on DVD. Zombie is available as Zombie AND Zombi 2 (just different packaging), while the European cut of Dawn of the Dead is available as Zombi. Meaning we have Zombi, Zombie, Zombi 2, Zombie 3, Zombie 4, and Zombie 5.
* According to popular myth, the reason the play ''Theatre/TheMadnessOfGeorgeIII'' was filmed as ''Film/TheMadnessOfKingGeorge'' was in case people avoided it until they'd seen ''The Madness of George'' and ''The Madness of George II''.
** Along similar lines, though this was just a joke, was the story of people wondering how they had missed seeing the nine prequels to Spike Lee's ''Malcolm X''.
** A similar joke is used in a ''Series/ThirdRockFromTheSun'' companion guide, which features the aliens documenting their understanding of Earth. When describing the concept of movies, Dick cites ''Film/{{Apollo 13}}'' and ''Film/TheSeventhSeal'' as examples of movie sequels. He then mistakes the film ''Film/{{Se7en}}'' for being a prequel to the Creator/BlakeEdwards film ''10''.
* ''Film/BackToTheFuturePartII'' is a victim of this trope, along with ''Film/BackToTheFuturePartIII''.
* The entries in Matthew Barney's avant-garde "Cremaster cycle" were filmed out of their numerical order: ''Cremaster 4'' (1994), ''Cremaster 1'' (1995), ''Cremaster 5'' (1997), ''Cremaster 2'' (1999), and finally ''Cremaster 3'' (2002).
* In the Creator/JerryStiller film ''Film/TheIndependent'', long-time exploitation film director Morty Fineman is asked by the filmmaker -- it's a {{Mockumentary}} about Fineman's fictional career -- if it's true he invented the sequel. Fineman corrects that, saying he invented the roman numeral after the title. The film then shows the title card from his post-nuclear sequel, ''World War III II''.
* The ''Franchise/FridayThe13th'' series is surprisingly consistent with this. Of the 10 movies (excluding ''Film/FreddyVsJason''), 7 of the movies were numerically numbered, with #4 being (the misleading) ''[[Film/FridayThe13thTheFinalChapter The Final Chapter]]'', and #9 being ''Film/JasonGoesToHellTheFinalFriday''. #10 uses the roman numeral ''[[Film/JasonX X]]''. Because [[XtremeKoolLetterz it's cool]] and took place [[RecycledINSPACE in space]].
** Spoofed in the British slasher satire ''UnmaskedPart25'', which also ends with the killer shouting a BigNo upon seeing ''Unmasked Part 26'' on a cinema marquee.
* ''Franchise/ANightmareOnElmStreet'' was similar, with five numbered sequels, then ''Film/FreddysDeadTheFinalNightmare'' (which is not much misleading, as all the following sequels and ''Film/FreddyVsJason'' have him truly dead) and ''Film/WesCravensNewNightmare''.
* A gimmick employed by a few franchises is to have the second sequel to the original movie filmed in 3-D, so the number affixed to its title can be "3-D" instead of just plain 3. See ThirdIs3D.
* The four movies of the Franchise/{{Rambo}} franchise were originally named and ordered thusly: ''Film/FirstBlood'', ''Film/RamboFirstBloodPartII'', ''Film/RamboIII'', and ''Film/{{Rambo}}''. Note how "Rambo" goes from being the subtitle of the second movie to the main title of the third. The fourth movie, released twenty years after the third, is a clear case of StoppedNumberingSequels.
** In France, the [[MarketBasedTitle exported titles]] are ''Rambo'', ''Rambo II'', ''Rambo III'' and ''John Rambo''.
*** In Brazil, it's more straightforward, with some [[TheForeignSubtitle subtitles added]]: ''Rambo - Programmed to Kill'', ''Rambo II: The Mission'' (fun fact: "The Mission" is the equivalent of "ElectricBoogaloo" in that country), ''Rambo III'' and ''Rambo IV''.
** The planned fifth movie is titled ''Rambo V''. This sounds fine, and actually logical, until you realise that means they're following up ''Rambo'' with ''Rambo V''.
* Each of the sequels to ''Film/TheFastAndTheFurious'' uses a different title format, most of which incorporate the movie's number in some way. The [[OddlyNamedSequel2ElectricBoogaloo second movie]] was titled ''Film/TwoFastTwoFurious''. The next two were unnumbered: ''Film/TheFastAndTheFuriousTokyoDrift'' and ''Film/FastAndFurious'' these names make more sense than it appears, as ''Tokyo Drift'' is a sequel InNameOnly while the fourth film is a return to the original cast and setting. Then the fifth movie goes back to numbers is called ''Film/FastFive'', followed by ''Film/FastAndFurious6'', then ''Film/Furious7''. The eighth movie ''Film/TheFateOfTheFurious'' is technically unnumbered but does incorporate the sound of the number in its title (i.e. "F'''ate'''").
* Parodied in National Lampoon's ''Film/LoadedWeapon1'', which does not have any sequels to justify the "1."
** Same with Creator/MelBrooks' ''Film/HistoryOfTheWorldPartI'', though it does end with a RealTrailerFakeMovie for Part 2.
*** That one is actually a [[GeniusBonus subtle]] [[http://en.wikipedia.org/wiki/Walter_Raleigh history joke]].
** ''Film/{{Spaceballs}}'' mentions a numbered sequel subtitled ''The Search For More Money'' but it was never made.
*** An alternative title of ''Spaceballs 3: The Search for Spaceballs 2'' was also rumored.
** ''Film/RobinHoodMenInTights'' also mentions an unmade numbered sequel.
* Also parodied in ''Film/LeonardPart6'', which claims that the first five adventures of the hero are so secret that the movies were covered up.
* The ''Franchise/StarTrek'' movies did this starting with ''[[Film/StarTrekIITheWrathOfKhan Wrath of Khan]]'' and ending with ''[[Film/StarTrekVITheUndiscoveredCountry Undiscovered Country]]'', spanning all of the films based on [[Series/StarTrekTheOriginalSeries the original series]]. Movies based on ''[[Series/StarTrekTheNextGeneration The Next Generation]]'' abandoned it though they are sometimes referred to as 7 through 10 by the fans. As the [[Film/StarTrek 2009 film]] is simply called ''Star Trek'', it is also unofficially referred to as ''Star Trek XI''.
* The ''Franchise/{{Saw}}'' film series went from 1 to 6 (using Roman numerals for the second to sixth films). Then an [[OddlyNamedSequel Oddly Numbered Sequel]] (at least over here) is the seventh movie, known as ''Film/Saw3D''.
* ''Film/KingKongLives'' was released as ''King Kong 2'' in several countries.
* The [[Film/HarryPotter two movies]] based on the last ''Literature/HarryPotter'' book are titled ''Film/HarryPotterAndTheDeathlyHallowsPart1'' and ''Film/HarryPotterAndTheDeathlyHallowsPart2''. The choice of Arabic numerals over Roman numerals is odd, as these films are the epic finale to the whole series and also decidedly lack any kind of futuristic bent.
* The first three ''Film/MissionImpossible'' films do this. From the fourth movie onwards, they use subtitles instead.
* ''Film/MenInBlack'' has two sequels but the first uses Roman numbers (''Film/MenInBlackII'', stylized ''MIIB'') and the latter using regular Arabic ones (''Film/MenInBlack3'', stylized ''MIB[[superscript:3]]'').
* ''Franchise/MarvelCinematicUniverse'':
** Played straight with the ''Film/IronMan'' sequels.
** Averted in the sequels for ''Film/{{Thor}}'' (''The Dark World'' and ''Ragnarok'') and ''Film/CaptainAmericaTheFirstAvenger'' (''The Winter Soldier'' and ''Civil War''). The first sequel to ''Film/TheAvengers2012'' also went the subtitle route with ''Film/AvengersAgeOfUltron'' (emitting the "The"), and ''Film/AvengersInfinityWar'', the two films of which are using Part 1 and Part 2.
** The sequel to ''Film/GuardiansOfTheGalaxy'' was originally announced as ''Guardians of the Galaxy 2'', being the first MCU sequel outside of Iron Man to play it straight. Later the title was changed to ''Guardians of the Galaxy '''Vol.''' 2'', emulating a mix-tape like those seen in the first film.
* The ''Film/ScaryMovie'' sequels began with numbers but switched to Roman numerals for ''Scary Movie V''.
* The second sequel to ''Film/{{Alien}}'' was titled ''Film/{{Alien 3}}''.
* ''Film/TrueRomance'': Discussed InUniverse. Hollywood producer Lee Donowitz is most famous for his 80s Vietnam action movie ''Coming Home in a Bodybag''. When he asks his assistant Elliot (who's an informant for the cops by that point) about ideas for a sequel title, the latter just replies "''Coming Home in a Bodybag 2''". Donowitz snarks that his member is more creative than that.
* The first two sequels to ''Film/TheTerminator'' used numbers ''and'' subtitles, but removed the word "The" from the original title.

* German novelist Creator/KarlMay was a pioneer of this when he started to publish his adventure stories into volumes. It began in 1892 when he wrote ''Literature/{{Winnetou}} I'' as a prequel to the existing stories featuring the Apache chief, some of which were collected in ''Winnetou II'' and ''Winnetou III'', which came out the same year; ''Winnetou IV'' was published in 1910. Other May book titles with Roman numerals are ''Old Surehand I-II'' (1894-1895), ''Im Lande des Mahdi I-III'' (1896), ''Satan und Ischariot I-III'' (1896-1897), ''Im Reiche des silbernen Löwen I-IV" (1898-1903), and ''Ardistan und Dschinnistan I-II'' (1909).
* One of the few literary examples is ''Rama II'', and there the title can also be taken to refer to the spaceship the book features.
* The sequel to Creator/EEDocSmith's ''[[Literature/SkylarkSeries The Skylark of Space]]'' was called ''Skylark Three'', again after a ship starring in the story.
* Another is ''Fantastic Voyage II'', written by Creator/IsaacAsimov, who novelized the original ''Fantastic Voyage'' and is often mistaken for its original creator because the novelization came out first. This may not technically be considered a sequel because Asimov only used the basic concept.
* ''Film/{{Psycho}}'' was [[AdaptationDisplacement originally a book]]. The sequel ([[AlternateContinuity which was never filmed]]) was called ''Psycho II''. None of the actual Psycho sequel films adapt Bloch's sequels, ''Psycho II'' and ''Psycho House''.
* A similar situation exists with Brian Garfield's sequel to ''Literature/DeathWish'', ''Death Sentence''. None of the Charles Bronson sequel films adapted it. ''Death Sentence'' was later filmed with a different hero.
* Creator/MartinCaidin's first book about Steve Austin, ''Cyborg'', had three sequels, with the last named ''Cyborg IV'' (the other two had completely different names).
* Gary Brander wrote ''Howling II'' and Howling ''III''.
* Numerous paperback original series such as the Destroyer, the Penetrator, the Marksman, etc. had numbered titles.
* The UK versions of ''Literature/ThePrincessDiaries'' by Meg Cabot have fun with this; the sequels are called ''The Princess Diaries: Take Two'', ''The Princess Diaries: Third Time Lucky'', ''The Princess Diaries: Mia Goes Fourth'', ''The Princess Diaries: Give Me Five'', ''The Princess Diaries: Sixsational'', ''The Princess Diaries: Seventh Heaven'', ''The Princess Diaries: After Eight'', and ''The Princess Diaries: To the Nines''.
* The Literature/StephaniePlum novels by Janet Evanovich take this to the extreme, being no more than a short phrase containing the number in the series (except for holiday specials). The series goes from ''One For the Money'', ''Two for the Dough'' and ''Three to Get Deadly'' all the way to ''Explosive Eighteen'' in 2011.
* Megan [=McCafferty=]'s popular Literature/JessicaDarling series includes ''Sloppy Firsts'', ''Second Helpings'', ''Charmed Thirds'', ''Fourth Comings'', and ''Perfect Fifths''.
* Several ''Literature/MarcusDidiusFalco'' novels had a count ''down.'' Thus ''Three Hands in the Fountain'' was followed by ''Two for the Lions'' and then ''One Virgin Too Many''. Since the Romans never got around to inventing the number zero, subsequent novels had to drop the numerical theme.
* David Charney wrote ''Sensei'' and ''Sensei II: The Swordmaster''.
* The second to fourth''Discworld/TheScienceOfDiscworld'' books are numbered and [[ElectricBoogaloo subtitled]] as ''The Science of Discworld II: [[Creator/WilliamShakespeare The Globe]]'', ''The Science Of Discworld III: [[UsefulNotes/CharlesDarwin Darwin's]] Watch'' and ''The Science of Discworld IV: Judgement Day''.
* Some printings of ''Literature/TheSecondJungleBook'' use the title ''The Jungle Book II''.
* ''Literature/WaylanderII'' by ''Creator/DavidGemmell''

[[folder:Live-Action TV]]
* Creator/TheBBC science fiction comedy series ''Series/RedDwarf'' opened its third series with a ''Star Wars'' spoofing scroll past of text ending with the line Red Dwarf III: The Same Generation (Nearly). This led the BBC's official listings magazine, the Radio Times, to list the series as Red Dwarf III. Subsequent series were likewise shown as Red Dwarf IV, Red Dwarf V and so on. Eventually, the creators began numbering the series on screen... after which the Radio Times just called it Red Dwarf. This was dropped for the ''Back to Earth'' three-parter, although it is referred to (usually unofficially) as Series IX.
** The 2012 series is referred to as Red Dwarf X which does officially make the Back to Earth three-parter a mini-series.
* Another BBC comedy, ''Series/BlackAdder'', was followed by ''Blackadder II'', ''Blackadder the Third'' and ''Blackadder Goes [[PunBasedTitle Forth]]''
* In ''Series/RobotWars'' if a team came back with a new version of an old robot they would often call it (Name of Robot) 2 (or whichever number they got up to), one example would by Firestorm which by the time the series ended had got up to Firestorm 5!
* An early episode of ''[[Series/LawAndOrderSpecialVictimsUnit Law & Order: SVU]]'' was called "Closure." In the second season, the victim from that episode was brought back as a vigilante. The follow-up episode was called "Closure 2."
** Which is kind of an oxymoron if you think about it.
* ''Series/StrangerThings'' Season 2 named itself as ''Stranger Things 2''.

* Many a ChronologicalAlbumTitle overlaps with this trope.
* Music/LedZeppelin's self-titled debut album was followed later the same year by ''Led Zeppelin II'', and by ''Led Zeppelin III'' the following year. The untitled album that followed it is informally called ''Led Zeppelin IV'' by fans.
* Music/MeatLoaf's breakout album ''Bat Out of Hell'' was followed sixteen years later by ''Bat Out of Hell II: Back Into Hell'', with ''Bat Out of Hell III: The Monster Is Loose'' following thirteen years after that.
* Music/{{Metallica}} released the song "The Unforgiven" on their self-titled album. Six years later, on the album ''Reload'', came the song "The Unforgiven II". Subverted a bit in the lyrics; they are about the Unforgiven from the previous song finding a lifemate and asking "are you unforgiven [[{{Pun}} too]]?".
** And another twelve years later, on ''Death Magnetic'', Metallica released "The Unforgiven III". Strangely enough, it's the only song in the cycle that ''doesn't'' contain the word Unforgiven in any of the lyrics, and musically and lyrically it has very little to do with the other two.
*** Although it doesn't contain the musical motif or the word "Unforgiven" it does have the lyrics "And how can I blame you, when it's me I can't ''forgive''?"
* Music/GunsNRoses ''Use Your Illusion I & [=II=]'' (though released simultaneously)
* Music/PinkFloyd's ''Music/TheWall'' has the three-part song "Another Brick In the Wall" ([[BlackSheepHit the one involving schoolteachers]] is Part II).
* Music/KingCrimson started the "Larks' Tongues In Aspic" sequence of songs with Parts 1 & 2 bookending the ''Larks' Tongues In Aspic'' album in 1973, continued with Part III (switching to the Roman numeral convention) on 1984's ''Three Of A Perfect Pair'', and concluded it with Part IV (which itself consists of three separate but identically-titled tracks) in 2000, on the album ''The [=ConstruKction=] Of Light''.
* Like Music/LedZeppelin, Music/{{Queen}}'s debut album was the eponymous ''Queen'', which was followed by ''Queen II'' a year later.
* Music/{{Chicago}}. They're up to about ''Chicago 30'' now.
* Music/{{Overkill}}'s self-titled song has currently four sequels.
* ''The Dethalbum'' by Dethklok was followed by ''The Dethalbum II''. Also, "Murmaider" from the former was followed by "Murmaider II: The Water God" on the latter.
* Most of Music/NineInchNails' albums, singles and [=EPs=] have a "Halo number" appended to the title, indicating the chronological order of its release. ''The Downward Spiral'', for example, is designated "Halo 8", while their most recent release, ''The Slip'', is "Halo 27". Usually the releases that don't have a Halo number are releases that Reznor's record company forced him to release and fall under CanonDiscontinuity.
* As a response to the [=NWOBHM=], Guitar Player columnist Mike Varney established the Shrapnel Records label, and issued a ''U.S. Metal'' compilation to spotlight unsigned American metal bands. ''U.S. Metal Vols. II-IV'' followed.
* An unusual case of this happening with a band name: King Missile III, so named because it was the second time they'd made significant lineup changes since forming. Technically, there was never a King Missile II: The first incarnation of the band was King Missile (Dog Fly Religion) and the second was simply King Missile.
* Big Audio Dynamite became Big Audio Dynamite II once Mick Jones was the only original member left.
* Normally, in classical music, number of works isn't really that important, but there's a particular superstition around writing exactly nine numbered symphonies...
** Gustav Mahler, superstitious that several other previous composers had died either leaving 9 symphonies, or 8 and an unfinished 9th, at one time said that the symphony now numbered his 9th was actually his 10th, by counting the symphonic cantata "Das Lied von der Erde" as a symphony and thus as his actual ninth (this is what qualifies him for this trope). Subverted in that nobody else has since accepted that renumbering, so "Das Lied" remains defined as a symphonic cantata, is NOT counted in the sequence of symphonies, and the 9th symphony as a 9th. Oh, and he died shortly afterwards, leaving sketches for a half-completed 10th.
** Double subverted in that the examples Mahler was thinking of were Beethoven, Schubert, Dvorak and Bruckner... but of those, Schubert's "7th" never existed beyond the sketch stage (and still doesn't), the 8th is famously unfinished (and performed in its incomplete version), the 9th *was* completed, but none of them beyond the 6th were published during his lifetime: Bruckner died part-way through writing his own 9th (still performed in its incomplete version) but left at least two "unnumbered" published student works to which critics have given the numbers "0" and "00": and Dvorak retired after *his* 9th, lived quite a few years afterwards without attempting to write another one, but had attempted to withdraw his first four symphonies from publication and refer to symphonies 5-9 as 1-5, and they were published under those numbers for years until the earlier ones were rediscovered... leaving only Beethoven as someone who had definitely written exactly 9 symphonies. (And also left partial sketches for one or two movements of a 10th, but had apparently not touched them for some time.)
** On the other hand, both Ralph Vaughan Williams and Malcolm Arnold have written 9 symphonies and then died. At a very advanced age in both cases.
* Music/VanHalen has a weird case: ''Van Halen II'' is a ChronologicalAlbumTitle (and basically a sequel to the SelfTitledAlbum as well). ''Van Halen III'' is the band's 11th - but third line-up.
* Music/TheBeatles' sixth album released by Capitol Records in the U.S. was ''Beatles VI''.
* The first two albums by Music/{{Queen}} are titled ''Queen'' and ''Queen II''. They also released ''Greatest Hits'', ''Greatest Hits II'' and ''Greatest Hits III''.
* {{Music/Periphery}} title their albums like this; Icarus Lives (sometimes just called Icarus or Icarus EP) and [[OneWordTitle Clear]] are exempt because they're eps. As is Juggernaut Alpha/Omega as that's a (technically two) [[ConceptAlbum concept album(s)]] outside of their regular releases. That leaves us with Periphery and Periphery II: This Time it's Personal with Periphery III on its way.
* Music/JeanMichelJarre named the 2016 second "sequel" to his 1976 classic ''Music/{{Oxygene}}'' ''Oxygène 3''. While he was at it, he renamed the 1997 first sequel (formerly known as ''Oxygène 7-13'') ''Oxygène 2''. Yes, this interferes with the track naming on many Jarre albums including all three ''Oxygène''s that uses numbers instead of titles, too; "Oxygène 2" and "Oxygène 3" are shortened names for "Oxygène (Part II)" and "Oxygène (Part III)" from the first ''Music/{{Oxygene}}''.
* ''The Dear Hunter'' is writing six concept albums that tell one continued story, which are entitled, in chronological order, as follows: ''Act I: The River South, The Lake North'', ''Act II: The Meaning Of, And All Things Regarding, Ms. Leading'', ''Act III: Life And Death'', ''Act IV: Rebirth In Reprise'', and ''Act V: Hymns With The Devil In Confessional''. As of yet, Act VI has not been released.

[[folder:Professional Wrestling]]
* Wrestling/{{WWE}}'s ''Wrestling/WrestleMania'' Pay-Per-View events are normally numbered (although they seem to have trouble deciding whether to use Roman or Hindu\Arabic numerals), with three exceptions: the sixteenth was dubbed ''Wrestlemania 2000'' [[{{Trope2000}} to capitalize on millennial fever (and because it was in the year 2000)]], and the seventeenth and eighteenth were ''Wrestlemania X-Seven'' and ''Wrestlemania X8'', respectively, for XtremeKoolLetterz effect. Their other Pay-Per-View events don't use any form of numbering, instead being identified by the year in which they were held
** The only other Wrestlemania not to use Roman numerals was 13 - which was promoted with Arabic numerals.
*** 21, 22, and 23 used Hindu\Arabic numerals as well (the installments between 2005 and 2007).
*** 2012 sees a return to Hindu\Arabic numbers with 29, although its logo is still shown as "''[[http://upload.wikimedia.org/wikipedia/en/a/aa/WrestleManiaXXIXlogo.png WrestleMania NY NJ]]''". 29 also began a trend of the logos just dropping the number altogether (31 is "''[=WrestleMania=] Play Button''", 32 is "''[=WrestleMania=] Star''", and 33 will be "''[=WrestleMania=] Sun''"; although all the shows are still appropriately numbered on the WWE Network). 30 is the exception to this, as it's a MilestoneCelebration so they retained the numbering with a Roman numeral (''[=WrestleMania=] XXX'').
** ''[=WrestleMania=] XXV'' was promoted as "''[=WrestleMania=] [[MilestoneCelebration 25th Anniversary]]''" or "''The 25th Anniversary of [=WrestleMania=]''".
* Wrestling/{{WCW}}'s first nine ''Superbrawl'' PPV events were appropriately numbered, then the next was named ''Superbrawl 2000'' much like WWF did with ''Wrestlemania''. This was followed by ''Superbrawl Revenge'', the final Superbrawl before WCW was closed down.
* When Wrestling/{{TNA}} began numbering their annual Slammiversary show (so named because it marks the anniversary of the company's founding) beginning with the 2010 event, they decided to number the shows based on which anniversary they were celebrating rather than how many Slammiversary events had been held. This means that the 2014 event, Slammiversary XII, is the tenth event in the series.

* William Creator/WilliamShakespeare's ''Theatre/HenryIV, part 2'', and ''Henry VI, parts 2 and 3''
** Spoofed by ''The Book of Sequels'', a book consisting of humorous fictional sequels, spinoffs, and adaptations of famous works, with ''Romeo and Juliet Part 2'', which reveals that Romeo's poison was actually a sleeping potion, the knife was [[ActuallyADoombot actually a fake prop knife]], and that Romeo and Juliet [[SequelReset live on]] to go on a bunch of wacky adventures.

[[folder:Video Games]]
* Only three of the first six ''Franchise/FinalFantasy'' games were released in North America. Two of those -- ''[[VideoGame/FinalFantasyIV IV]]'', and ''[[VideoGame/FinalFantasyVI VI]]'' -- were renumbered for North American release, making them ''II'', and ''III''. This was made all the more confusing when, starting with ''VideoGame/FinalFantasyVII'', Square decided to release the games with their proper numbers globally, making it seem in North America as though ''Final Fantasy IV-VI'' had simply vanished. This was further muddled when the NES and SNES games were rereleased worldwide on other consoles and given their original numbers.
** The series also features ''VideoGame/FinalFantasyX2'', which - perhaps confusingly for some - is neither ''VideoGame/FinalFantasyXI'' nor ''VideoGame/FinalFantasyXII''. Or ''VideoGame/FinalFantasyVIII'', for that matter.
** ''VideoGame/FinalFantasyXI'' and ''VideoGame/FinalFantasyXIV'' are {{MMORPG}}s; every other ''Franchise/FinalFantasy'' game is a single-player {{RPG}}. The former makes this distinction with its official title being "Final Fantasy XI: Online".
** Notably, ''VideoGame/FinalFantasyX2'' is the only direct sequel of a game to be named like that. All the others (''[[Anime/FinalFantasyVIIAdventChildren Advent Children]]'', ''[[VideoGame/FinalFantasyXII Revenant Wings]]'', ''[[VideoGame/FinalFantasyIVTheAfterYears The After Years]]'', ''VideoGame/DirgeOfCerberus'') are sticking with just a subtitle.
*** ''VideoGame/FinalFantasyX2'' may have started a trend within the franchise since ''VideoGame/FinalFantasyXIII'' has gotten a direct sequel named ''Final Fantasy XIII-2''. Also, XIII got a SECOND SEQUEL, named ''Lightning Returns: Final Fantasy XIII'', making the XIII games a mini trilogy.
** There also exist ''Final Fantasy Legend II'' and ''III'' for the original Game Boy. In Japan these are part of the ''[[Franchise/SaGaRPG SaGa]]'' series, also numbered 2 and 3. The same series has sub-series with numbered sequels in ''Romancing [=SaGa=] 2'' and ''3'', as well as ''[=SaGa=] Frontier 2''.
* Trying to arrange the ''VideoGame/KingdomHearts'' games in chronological order can get confusing. Birth by Sleep is the first Kingdom Hearts game by canon, despite coming out 8 years after ''VideoGame/KingdomHeartsI'', which was the first released title. ''VideoGame/KingdomHeartsII'', the only game with a straightforward numbered subtitle, was neither the second game released nor the second chronologically (''VideoGame/KingdomHeartsChainOfMemories'' being both). The most recent game, ''VideoGame/KingdomHearts3DDreamDropDistance'', while the direct sequel to ''II'', is ''not'' the long-awaited ''Kingdom Hearts III''. According to Nomura, ''III'' is to be release next after the HD remasters, and it will be the ''eighth'' game in the series (ignoring updated rereleases).
** To make things even more fun, Nomura has stated that KingdomHeartsX is 0, as it is chronologically first, Birth by Sleep is 0.1 since it comes after that, and Dream Drop Distance is ''2.6'' because it happens after all of the games contained in ''Kingdom Hearts HD 2.5 [=ReMIX=]''.
* The ''VideoGame/SimCity'' series has had a lot of fun with this one: the first sequel was named ''VideoGame/SimCity 2000'', presumably in homage to the year 2000, one of the game's optional starting dates. The third game was then named ''VideoGame/SimCity 3000'', presumably because it would be odd to go from 2000 to 3 in terms of sequel numbering. (Though nobody told that to the Pokemon movie people.) Of course, the fourth game was called ''VideoGame/SimCity 4''.
** And now the game that should be VideoGame/SimCity 5 is simply titled VideoGame/SimCity because it's a reboot of the series.
* The ''VideoGame/UnrealTournament'' series also had its share. The original was called simply ''Unreal Tournament'', the sequel was ''Unreal Tournament 2003'' (to sound like other sports titles such as ''Madden 2004'' - they wanted to emphasize the 'bloody sporting competition' aspect). The [[MissionPackSequel Madden-esque]] sequel/re-tool of that was ''VideoGame/UnrealTournament2004''. The next game was originally ''Unreal Tournament 2007'', but now it's just ''VideoGame/UnrealTournamentIII''. Apparently, even the developers didn't think 2004 was that different from 2003.
** The [=200X=] games were both based on the Unreal Engine 2. UT 3 uses an entirely new engine (The Unreal Engine 3, naturally), and is therefore the third generation of the series.
*** There's more reasons, too. [=UT2003=] was rushed, so they released [=UT2004=] as sort of an upgrade. As such, they count as one game. The series also had singleplayer-oriented games, with the original ''VideoGame/{{Unreal|I}}'' and then ''VideoGame/Unreal2TheAwakening'' between ''[=UT2003=]'' and ''2004''. [=UT3=] has both a singleplayer campaign and ''Tournament''-like multiplayer modes, so it counts as Unreal 3 as well as Unreal Tournament 3. Phew.
*** And to cap it all off for extra confusion, ''VideoGame/UnrealTournament2015'' did away with numbers altogether and is just ''[[RecycledTitle Unreal Tournament]]'', with official sites instead retroactively referring to the first game as its post-''2003'' FanNickname of ''Unreal Tournament '99''.
* Depending on which games you count as canon, ''VideoGame/{{Worms}} 4: Mayhem'' was either the sixth, seventh, eighth or ninth Worms game.
* The Japan-only ''Franchise/ShinMegamiTensei NINE'' is almost a subversion: [[MultipleEndings 'nine' is the number of endings,]] the main series only having 3-5 games depending on what you count as a spin-off. Counting spin-offs and remakes, the number of games actually jumps over 50...
** Spinoff series ''[[Franchise/ShinMegamiTenseiPersona Persona]]'' has six main games, even though the latest one released is only titled ''[[VideoGame/Persona5 5]]''. This is because [[VideoGame/Persona2 the second game]] is [[OneGameForThePriceOfTwo actually two games]]. The spinoff sequels of the fourth game are simply named ''VideoGame/Persona4 *[[VideoGame/Persona4Arena insert]] [[VideoGame/Persona4ArenaUltimax subtitle]] [[VideoGame/Persona4DancingAllNight here]]*'', but ''VideoGame/PersonaQShadowOfTheLabyrinth'', which is a {{Midquel}} to [[{{Crossover}} both the third and fourth games]] (weird time shit is involved) [[LetteredSequel drops the numbering]] rather than associating it with one game over the other.
* ''VideoGame/SuperMarioWorld'' actually had a subtitle when it was first released in Japan, namely ''SuperMarioBros 4''. Then, for the Western releases of VideoGame/YoshisIsland, it had the subtitle "Super Mario World 2". And in the handheld world, the first game of the Wario spinoff series was named ''VideoGame/WarioLand: VideoGame/SuperMarioLand 3''.
** ''VideoGame/WarioLand'' fits this trope to a T, with Wario Land games 1-4. (Though ''Wario Land II'' is numbered with the Roman numeral, unlike 3 and 4, and all later Wario games used subtitles rather than numbers.)
** When the ''Super Mario'' games were rereleased for the UsefulNotes/GameBoyAdvance, gamers were treated to ''[[VideoGame/SuperMarioBros2 Super Mario Advance]]'' ''';''' ''[[VideoGame/SuperMarioWorld Super Mario World: Super Mario Advance 2]]'' ''';''' ''[[VideoGame/YoshisIsland Yoshi's Island: Super Mario Advance 3]]'' ''';''' and ''[[VideoGame/SuperMarioBros3 Super Mario Advance 4: Super Mario Bros. 3]]''.
* ''VideoGame/MarioParty'' has numbered sequels from 1-10.
* Mostly avoided by ''VideoGame/MarioKart'', which instead went for the SuperTitle64Advance format (though the Game Boy Advance and Nintendo [=GameCube=] installments were examples of OddlyNamedSequel2ElectricBoogaloo). It succumbed to this trope starting with ''VideoGame/MarioKart7'', although the numeral in ''VideoGame/MarioKart8'' is shaped like a Mobius strip to highlight the antigravity segments present in some tracks. Technically, ''Mario Kart 7'' would be the ''ninth'' game in the series and ''8'' the 11th if arcade installments were counted.
* ''VideoGame/SuperMarioBrosTheLostLevels'', ''VideoGame/SuperMarioBros2'', ''VideoGame/SuperMarioBros3'', ''VideoGame/SuperMarioLand2SixGoldenCoins'', and ''VideoGame/SuperMarioGalaxy2''.
* The ''{{VideoGame/Contra}}'' series only had two numbered sequels. ''Contra III: The Alien Wars'' for the SNES, which directly followed the original arcade and NES games, ''Contra'' and ''Super Contra'' (aka ''Super C''), although ''Contra III'' was just the MarketBasedTitle for the American version (the Japanese version was titled ''Contra Spirits''). The second numbered sequel was ''Contra 4'' for the Nintendo DS, although it was released more than a decade later after other ''Contra'' sequels were made. The "4" on its title has less to do with its release order and more to do with its setting (taking place after ''Contra III'', but before ''Contra: Shattered Soldier'')..
* The Anno series started with ''Anno 1602'', then 1503 (yes, exactly like that), then 1701, 1404, and 2070. The only pattern in this sequel numbering is that the numbers add up to 9.
* All of the 2D ''VideoGame/SamuraiShodown'' sequels received consecutive numbers from II to VI (plus V Special); however, in Japan, each game had a variation of the ''[[VideoGame/SamuraiShodown Samurai Spirits]]'' title and some were prequels. Still, ''Samurai Shodown V'' in Japan was ''Samurai Spirits'' '''''Zero'''''. The fictional chronology goes like this: V, VI, I, III, IV, and II.
* Subversion: '''VideoGame/{{Marathon}}'' was followed by ''Marathon 2'' which was followed by ''Marathon Infinity''. ''Infinity'' was then given a joke award by ''[=MacFormat=]'' for "largest version number increase." As if this wasn't enough, the game engine for ''Marathon 2'' was subsequently released and developed into an open-source version named ''Aleph One'', thereby restoring sequential numbering at the expense of being understandable by anyone who wasn't a math major. The subversion was partially justified, if that's the right term, in that much of the "plot" of ''Infinity'' was based on [[TheMultiverse universe hopping]] and the game was released with the creators' level-design, physics-editing, and graphics-editing tools so that [[GameMod players could make their own stories]], making the game "infinite."
* The sequel to the original ''VideoGame/{{BioShock|1}}'' was ''VideoGame/BioShock2'', but that was followed ''VideoGame/BioShockInfinite''.
* Creator/{{Infocom}}'s ''VideoGame/{{Zork}}'' series/universe started with ''Zork I'', ''II'' and ''III'', but after that got complicated, with the VideoGame/{{Enchanter}} Trilogy (''Enchanter'', ''Sorcerer'' and ''Spellbreaker'') and then titles like ''Beyond Zork'' and ''Zork Zero''.
* Another bizarre example is the ''VideoGame/LeisureSuitLarry'' series: The first three games were numbered normally, but after the third one the series' primary game designer realized he'd painted himself into a corner by giving the franchise closure in the third game. He then decided to skip the fourth chapter in the series altogether, and went on to make ''Leisure Suit Larry 5'' while leaving the events of the fourth game to the players' imaginations, so that he himself wouldn't have to explain how Larry got to where he was in the fifth game.
* ''VideoGame/HalfLife1'' being followed many years later by ''VideoGame/HalfLife2'', then the sequels (which even Valve admits should be referred to as ''Half-Life 3'') being called ''Half-Life 2: Episode One'' and ''Half-Life 2: Episode Two''.
* ''VideoGame/WizardsAndWarriors'' for the NES was followed by two sequels on the same console, ''Ironsword: Wizards and Warriors II'' and ''Kuros, Visions of Power: Wizards and Warriors III''. There was also a side-game for the UsefulNotes/GameBoy titled ''Wizards and Warriors Chapter X: The Fortress of Fear'', which came out between ''II'' and ''III'', making us wonder where ''IV'' to ''IX'' went.
* The ''VideoGame/MightAndMagic'' series tends to follow this trope but two entries are an exception. The fourth game dropped the number and called ''VideoGame/MightAndMagic: Clouds of Xeen'' while the fifth game was ''VideoGame/MightAndMagic: Darkside of Xeen''. Both can be combined to form one world and were later released as one game called ''VideoGame/MightAndMagic: World of Xeen''. This can be confusing for those who only know of the combined version, as they assume ''World of Xeen'' is #4 then wonder what happened to #5 when the next game in the series is ''VideoGame/MightAndMagic VI''.
* The original ''VideoGame/MegaMan'' sequels used Roman numerals in the actual games, even though the packaging logos always used Arabic numerals. This caused a bit of confusion when the SequelSeries ''VideoGame/MegaManX'' was eventually released, as some people assumed the letter "X" was the Roman numeral for ten and not the letter, even though a ''[[VideoGame/MegaMan7 Mega Man VII]]'' was eventually released for the SNES alongside ''X2'' and ''X3''. Capcom switched to Arabic numerals for the in-game logos starting with ''VideoGame/MegaMan8'', so there wasn't that much of a confusion anymore by the time the actual ''VideoGame/MegaMan10'' came out.
** In regards to the Game Boy games, both the ingame titles and the packaging logos always used Roman numerals... except for the fifth game, which still carried a Roman numeral for the title screen, yet the packaging logo had the same Arabic numeral problem as the console games at the time.
** Note that this was never an issue for the Japanese versions, where the ''Rockman'' sequels always used Arabic numerals.
* ''Franchise/FireEmblem'' is a notable aversion. Officially, the games are primarily identified by their subtitles, not numbers. However, the internal programming for most of the games [[http://www.nintendo.co.jp/fe/few_series.html and official sites]] do use numbered titles reflecting their placement in the series (i.e: the GBA games are numbered 6 to 8) and the English speaking fandom do use numbered titles as a shorthand for the sake of simplicity.
* ''Franchise/TheLegendOfZelda'' games are similar to the ''Fire Emblem'' games in the lack of numbers in the titles; only the second game ever released was a numbered sequel -- ''VideoGame/ZeldaIITheAdventureOfLink'', which was a direct sequel to the original game. As with the ''Fire Emblem'' series, most of the others are [[AnachronicOrder Nonlinear Sequels]], which probably accounts for the lack of numbers, although fans sometimes do refer to ''VideoGame/TheLegendOfZeldaALinkToThePast'' as "Zelda III".
** ''VideoGame/TheLegendOfZeldaALinkBetweenWorlds'' was actually called "Kamigami no Triforce 2" (Triforce of the Gods 2) in Japan, making it a numbered sequel to ''A Link to the Past''. Strangely, "Triforce of the Gods 2" is also the name used in Korea, even though "1" was released as "A Link to the Past" there, just like the other international releases.
* ''VideoGame/TouchDetective'' called its sequel ''Touch Detective 2½'' as an homage to the Naked Gun.
* The Franchise/StarWars ''VideoGame/{{Dark Forces|Saga}}'' series seems to be afraid of the number 3, instead numbering both the second and third game "2": after the original ''VideoGame/DarkForces'' was ''VideoGame/JediKnightDarkForcesII'', and then ''VideoGame/JediKnight2JediOutcast'', dropping the "Dark Forces". They then dropped the numbers entirely with ''VideoGame/JediKnightJediAcademy'' (not ''Jedi Outcast II'' or ''Dark Forces III'').
* The ''VideoGame/{{Battlefield}}'' franchise has 13 or so full games, and 21 installments if you include expansion packs. Sure enough, it eventually fell into this trope.
** It began with ''Battlefield 1942'', indicating its UsefulNotes/WorldWarII setting by year, and was remade much later as ''Battlefield 1943'' for seventh-generation consoles. They also reused the yearly title format for ''VideoGame/Battlefield2142'' to convey its future setting.
** The straighter example of sequel numbering began with ''Battlefield 2'' and the "modern day" series along with it, although it's the ''third'' game in the franchise after ''Battlefield 1942'' and ''Battlefield Vietnam''. It may have been named that due to being a truly "second generation" of Battlefield, with significant updates to the Refractor engine used at the time while ''Vietnam'' was more or less [[MissionPackSequel a total conversion]] of ''1942''.
*** ''VideoGame/Battlefield3'' (the ''eleventh'' game) and ''VideoGame/Battlefield4'' continue the trend of numbered entries being "modern combat" titles, but ''VideoGame/Battlefield1'' [[SubvertedTrope subverts]] it by having a UsefulNotes/WorldWarI setting - essentially the EpisodeZeroTheBeginning clause, but plus one.
** ''VideoGame/BattlefieldBadCompany'' also got a direct sequel called, quite unsurprisingly, ''Battlefield: Bad Company 2''.
* The ''VideoGame/SamAndMaxFreelancePolice'' episodes have tv-production-style episode numbers, in the form of "101" to "106" for Season 1, "201" through "205" for Season 2, and "301" through "305" for [[VideoGame/SamAndMaxTheDevilsPlayhouse Season 3]].
* ''Anubis II'' is not a sequel to anything - the title is meant to be read as "Anubis the Second".
* Most Franchise/{{Bemani}} series use "[game title] ''n''th Mix" (such as ''VideoGame/DanceDanceRevolution'', up to 7th Mix), though ''VideoGame/{{beatmania}} IIDX'' used "beatmania IIDX ''n''th Style" up to 10th Style. From IIDX 11 onards, IIDX uses just numbers followed by a subtitle ("RED" for 11, "Happy Sky" for 12, etc). ''pop'n music'' uses numbers too, with the 12th main installment onwards having subtitles ("Iroha" for 12, "Carnival" for 13, and such).
* ''VideoGame/InitialDArcadeStage'' used "Initial D Arcade Stage ver. ''n''" for the first three releases; the fourth game onwards drops the "ver," signifying an overhaul in the game's mechanics.
* ''VideoGame/BubbleBobble'': [[OddlyNamedSequel Oddly named]] [[NonLinearSequel Non Linear]] [[NumberedSequel Numbered Sequels]]: First there was ''VideoGame/RainbowIslands: The Story of Bubble Bobble II'', and ''Parasol Stars: The Story of Bubble Bobble III'' (whose subtitle was often altered to "Rainbow Islands II" by the European publisher). Then a ''Bubble Bobble '''Part''' 2'' comes out for NES and Game Boy, and then ''Bubble Symphony'' aka ''Bubble Bobble II'' comes out, and ''Bubble Memories: The Story of Bubble Bobble III''. This makes three second-installments and two third-installments.
* The ''VideoGame/{{Wild ARMs|1}}'' sequels are numbered 2 to 5 in America, but in Japan the sequels have the following subtitles: ''[[VideoGame/WildArms2 2nd Ignition]]'', ''[[VideoGame/WildArms3 Advanced 3rd]]'', ''[[VideoGame/WildArms4 The 4th Detonator]]'', and ''[[VideoGame/WildArms5 The Vth Vanguard]]''. Yes, that's a Vth.
** The TurnBasedStrategy game in the series inverts this pattern, being ''VideoGame/WildArmsXF'' in its North American release and ''Wild Arms Crossfire'' in Japan.
* The only numbered sequels to the original ''VideoGame/{{Castlevania|I}}'' were ''VideoGame/CastlevaniaIISimonsQuest'' and ''VideoGame/CastlevaniaIIIDraculasCurse'' for the NES, as well as the oddly named ''VideoGame/SuperCastlevaniaIV'' for the SNES. Ironically ''III'' is actually a ''prequel'' to the first game in terms of setting, while ''IV'' is a remake; neither had a numbered title in Japan. ''VideoGame/CastlevaniaTheAdventure'' for the UsefulNotes/GameBoy had its own sequel, titled ''VideoGame/CastlevaniaIIBelmontsRevenge''. The rest of the series simply used subtitles (most of the time).
* The first ''VideoGame/MetalGearSolid'' game is actually the third ''VideoGame/MetalGear'' game, following ''VideoGame/MetalGear1'' and ''VideoGame/MetalGear2SolidSnake'' on the [=MSX2=], but uses the word "Solid" as a substitute for the number "3" in the same manner multiple other games entering their third iteration around that time would [[ThirdIs3D call themselves 3D]]. The subsequent sequels kept the word "Solid" as part of the title and began a new line of numbered sequels (''[[VideoGame/MetalGearSolid2SonsOfLiberty MGS2]]'', ''[[VideoGame/MetalGearSolid3SnakeEater MGS3]]'', and ''[[VideoGame/MetalGearSolid4GunsOfThePatriots MGS4]]''). ''[[VideoGame/MetalGearSolidPortableOps Portable Ops]]'', despite being part of the ''MGS'' canon, is not counted as part of the numbered series due to the fact it's on a portable platform and Kojima had little to do with it. Ironically, Kojima's original intention for ''[=MGS2=]'' was to call it ''[=MGS III=]'' just to confuse people about the numbering (with the missing number supposedly being a plot point). And the latest installment is called ''VideoGame/MetalGearSolidVThePhantomPain'', or ''[=MGS V=]''.
* ''VideoGame/StreetFighterII'', the sequel to ''VideoGame/{{Street Fighter|I}}'', had its own [[CapcomSequelStagnation sub-series of pseudo-sequels]], none of which were named in anyway that reflected their release order. On the other hand, the original ''VideoGame/StreetFighterIII'' was followed by ''2nd Impact'' and ''3rd Strike'', and before that there was the ''VideoGame/StreetFighterAlpha'' prequel series, which had its own pair of sequels (''Alpha 2'' and ''Alpha 3''), as well as the ''EX'' series (''EX 2'' and ''EX 3''). Then there's ''VideoGame/StreetFighter2010'', an obscure NES platformer that has nothing do with the rest of the series and is named after the year it's supposed to take place.
* The ''VideoGame/{{Metroid}}'' series does a weird mix with numbering. After the first Metroid game, the next game was dubbed ''VideoGame/MetroidIIReturnOfSamus''. In the 3rd game, people clearly see "Metroid 3" in the opening scene, but it does not appear in ''VideoGame/SuperMetroid'''s official title. Done again with "Metroid 4" for ''VideoGame/MetroidFusion''. The ''VideoGame/MetroidPrime'' series have their own set of numbered sequels with ''[[VideoGame/MetroidPrime2Echoes Echoes]]'' and ''[[VideoGame/MetroidPrime3Corruption Corruption]]'' bearing 2 and 3 in their titles, while ''VideoGame/MetroidPrimeHunters'' lacks a number. And then there's ''VideoGame/MetroidOtherM'', taking place between the third and fourth.
* ''VideoGame/GrandTheftAuto'' can be confusing to people who play it casually, or have little knowledge of it. It started out as ''VideoGame/{{Grand Theft Auto|Classic}}'', then got expansions, and was followed up with ''VideoGame/GrandTheftAuto2''. ''VideoGame/GrandTheftAutoIII'' (notice the change to Roman numerals) was released as a whole new gameplay style. Afterwards, they cut the numbers and started using the fictional city names as subtitles. They also released prequels, with the city name, and "Stories" in the title. Then, they released ''VideoGame/GrandTheftAutoIV'' (thus grouping all the city-ed games together as ''Grand Theft Auto III'' games), and made special episodes. So you can have people who believe that ''Vice City'' is ''GTA I'', ''Liberty City Stories'' is ''GTA II'', ''San Andreas'' is ''GTA III'', and ''Ballad of Gay Tony'' is ''GTA IV''. And if you show them ''Grand Theft Auto 1'' or ''2'', they will assume they are simply handheld ports of whatever they think ''I'' and ''II'' are.
** Rockstar seems to follow the "It's not a sequel unless the engine changes" rule of numbering. Most of the games between ''III'' and ''IV'' are referred to as "the ''[=GTA III=]'' era" for the dual facts that A) all of them use the same engine as ''III'' with minor updates and changes, and B) they're also the first games in the overall ''GTA'' series to have concrete story links to previous games - whereas the first two are entirely self-contained and separate stories, ''III'' ended up with a storyline spanning five distinct points in time over the course of 17 years.
* ''VideoGame/{{Rayman}}'' has had two numbered sequels with subtitles, ''VideoGame/{{Rayman 2}}: The Great Escape'' and ''VideoGame/Rayman3HoodlumHavoc''. Later for ''Rayman VideoGame/RavingRabbids'' with ''Rayman Raving Rabbids 2'' (''RRR'' itself was tentatively titled ''Rayman 4''). Averted with ''VideoGame/RaymanOrigins'', which is a prequel to the first game.
* The sequels to ''VideoGame/SakuraWars'' are ''Sakura Wars 2'', ''3'', ''4''... and ''[[VideoGame/SakuraWarsSoLongMyLove V]]''.
* The ''Franchise/{{Sonic|TheHedgehog}}'' series has become very cluttered with sequel numbers. The games for the UsefulNotes/SegaGenesis include ''VideoGame/SonicTheHedgehog'' (also called ''Sonic 1''), ''VideoGame/SonicTheHedgehog2'', ''Sonic the Hedgehog 3'' and ''Sonic & Knuckles'', [[OneGameForThePriceOfTwo the two halves]] of [[VideoGame/Sonic3AndKnuckles one game]]. Three console generations later, a fourth game was added to the series, called VideoGame/SonicTheHedgehog4.
** Sonic 1, of course, should not be confused with the [[RecycledTitle identically named]] ''[[VideoGame/SonicTheHedgehog2006 Sonic the Hedgehog]]'' (2006), which is not part of that series of games.
** Numerous other games in the franchise have their own sequels, some more straightforward than others:
*** ''VideoGame/SonicDrift 1'' & 2
*** ''VideoGame/SonicAdventure'', and ''VideoGame/SonicAdventure2'' ([[UpdatedRerelease rereleased]] as Sonic Adventure DX, and Sonic Adventure 2: Battle) neither of which are connected to ''VideoGame/TailsAdventure'' or ''{{VideoGame/Sonic Rush|Series}}'''s unnumbered sequel ''Sonic Rush Adventure''.
*** ''VideoGame/{{Sonic Advance|Trilogy}}'' 1, 2, and 3
*** And finally, not a direct sequel to anything, ''Sonic 3D'', which was released as ''Sonic 3D Blast'' in America, but ''VideoGame/Sonic3DFlickiesIsland'' in Europe to avoid confusion with the similarly named, but entirely unconnected ''VideoGame/SonicBlast'' for the UsefulNotes/GameGear.
* Creator/{{id Software}} likes to do this with their ''VideoGame/{{DOOM}}'' and ''VideoGame/{{Quake}}'' games, even if they tend to switch between Arabic and Roman for little reason (e.g. ''Doom II'' followed by ''VideoGame/{{Doom 3}}'', or ''VideoGame/QuakeIIIArena'' followed by ''VideoGame/Quake4''). The ''VideoGame/{{Wolfenstein}}'' series, however, has generally avoided this since ''[[VideoGame/Wolfenstein3D 3D]]'', probably thanks in part to the fact that it's been switching developers after every game or two - ''3D'' was followed on by ''VideoGame/ReturnToCastleWolfenstein'', then just ''VideoGame/{{Wolfenstein|2009}}'', and now ''VideoGame/WolfensteinTheNewOrder''.
** Finally averted (well over 30 years after the series started) with the 2017 sequel to ''The New Order'', ''VideoGame/WolfensteinIITheNewColossus''.
* The ''VideoGame/{{Jumper}}'' series, consisting of ''Jumper'', ''Jumper Two'' and ''Jumper Three''[[note]]and ''[[VideoGameRemake Jumper Redux]][[/note]]''.
* ''Franchise/AssassinsCreed'', which consists of the [[VideoGame/AssassinsCreedI original game]], ''VideoGame/AssassinsCreedII'', and ''VideoGame/AssassinsCreedIII''. Also includes a pair of sequels, ''VideoGame/AssassinsCreedBrotherhood'' and ''VideoGame/AssassinsCreedRevelations'' to the second game.
** Played with as the next game ''VideoGame/AssassinsCreedIVBlackFlag''.
** And then completely averted with ''VideoGame/AssassinsCreedRogue'' and ''VideoGame/AssassinsCreedUnity''.
** It should be noted that the chronology of the past characters does not always match the sequel numbers. For example, ''IV'' takes place before ''III'', since the Past!protagonist of ''IV'' is the grandfather of the Past!protagonist of ''III''. ''Rogue'' also takes place after ''IV'' but before ''III''.
* The three Creator/{{Compile}}-developed sequels to ''VideoGame/PuyoPuyo'' have puns on numbers. ''Tsū'', the Japanese word for expert, also sounds like the English word two; ''SUN'', when pronounced in English, sounds like the Japanese word for three; and the "yon" in ''Puyo Puyo~n'' means four.
* Namco [[FourIsDeath really, really didn't want to make a fourth game]] in the ''VideoGame/AceCombat'' series. When they had to, it was only under condition that its number was padded to ''VideoGame/{{Ace Combat 04|ShatteredSkies}}''. After ''VideoGame/AceCombat6FiresOfLiberation'' they StoppedNumberingSequels for a while, but that's in part because they seemed reluctant to continue the original storyline past ''6'' - between that in 2007 and the announcement of ''VideoGame/AceCombat7SkiesUnknown'' eight years later, none of the games were set in the same continuity.
* ''VideoGame/{{Gauntlet}}'' was soon followed by ''Gauntlet II'', and the non-arcade sequels valiantly attempted to carry on the numbering. ''Gauntlet: The Third Encounter'' was released exclusively for the UsefulNotes/AtariLynx, while U.S. Gold and Software Creations were authorized to make the entirely different ''Gauntlet III: The Final Quest'' for the European home-computer market. ''Gauntlet IV'' is actually a remake of the original game for the UsefulNotes/SegaGenesis.
* The ''VideoGame/{{Ys}}'' series had two different fourth installments produced concurrently: ''Ys IV: Mask of the Sun'' for the UsefulNotes/SuperFamicom and ''Ys IV: The Dawn of Ys'' for the UsefulNotes/PCEngine. The seventh game was titled ''Ys Seven'' instead of ''Ys VII''.
* Two different games titled ''VideoGame/{{Spelunker}} II'' were released in Japan: one for arcades, one for the Famicom.
* ''VideoGame/PokemonGoldAndSilver''[='=]s WorkingTitle was ''Pocket Monsters 2: Gold and Silver''. Years later, sequels to ''[[VideoGame/PokemonBlackAndWhite Black and White]]'' were made and titled ''VideoGame/PokemonBlack2AndWhite2''.
* The Unnkulia series features "Unnkulian Underworld: The Unknown Unventure", followed by "Unnkulia 2", "Unnkulia Zero", and "Unnkulia One-Half".
* ''VideoGame/{{Shinobi}} III: Return of the Ninja Master'' is a somewhat confusing title, as considerably more than two ''Shinobi'' titles were released before it. The Japanese title, ''The Super Shinobi II'', marks it as a sequel to the earlier UsefulNotes/SegaGenesis game [[MarketBasedTitle known elsewhere as]] ''The Revenge of Shinobi''.
* The ''VideoGame/TengaiMakyou'' GaidenGame ''Fuun Kabuki Den'' has a fake title screen reading ''Tengai Makyou III''. The real ''Tengai Makyou III'' was not released until eight years after ''Tengai Makyou IV''.
* The console games based on the ''Franchise/TeenageMutantNinjaTurtles'' franchise fall into SequelNumberSnarl, but in North America they are as follows:
** ''VideoGame/TeenageMutantNinjaTurtles''
** ''[[VideoGame/TeenageMutantNinjaTurtlesTheArcadeGame Teenage Mutant Ninja Turtles II: The Arcade Game]]''
** ''[[VideoGame/TeenageMutantNinjaTurtlesTheManhattanProject Teenage Mutant Ninja Turtles III: The Manhattan Project]]''
** ''[[VideoGame/TeenageMutantNinjaTurtlesTurtlesInTime Teenage Mutant Ninja Turtles IV: Turtles in Time]]''
* ''[[VideoGame/LuigisMansionDarkMoon Luigi's Mansion 2]]'' [[MarketBasedTitle is the European and Japanese name]] for what North America knows as ''Luigi's Mansion Dark Moon''.
* The ''VideoGame/{{Neptunia}}'' series is an odd case. The first game, ''VideoGame/HyperdimensionNeptunia'', was developed [[NoBudget on a shoestring]], so the game was developed to be a one-off with a completely satisfying GoldenEnding that left no loose ends. When the game turned out to be a SleeperHit in both Japan and the west, a sequel was announced and properly funded. Rather than completely abandon all the characters and/or blatantly RetCon the first game, the developers instead opted to reboot and retell the story while still marketing it as a sequel, branding the result ''VideoGame/HyperdimensionNeptuniaMk2''. When it came time for the third game, a direct sequel to ''mk2'' without any reboots, they simply spared everyone the confusion and titled it ''VideoGame/HyperdimensionNeptuniaVictory''.
* ''Operation Wolf 3'' was the only numbered sequel to ''VideoGame/OperationWolf''.
* None of the ''VideoGame/{{Dizzy}}'' sequels carried numbers in the titles, but ''Treasure Island Dizzy'', ''Fantasy World Dizzy'', ''Magicland Dizzy'' and ''Spellbound Dizzy'' displayed "Dizzy II," "Dizzy III," "Dizzy IV" and "Dizzy V" on the StatusLine.
* The two {{samurai}}-themed {{Platform Game}}s developed by Vivid Image were titled ''First Samurai'' and ''Second Samurai''.
* The sequel to ''VideoGame/{{Vigilante 8}}'' was titled ''Vigilante 8: '''2'''nd Offense'' (''2nd Battle'' [[MarketBasedTitle in Japan]]).
* The fourth ''VideoGame/MagicalDrop'' game was titled ''Magical Drop F'' instead of ''Magical Drop IV'', in a blatant case of [[FourIsDeath tetraphobia]].
* ''VideoGame/FireProWrestling'' had two numbered sequels on the UsefulNotes/PCEngine, and ''Super Fire Pro Wrestling'' had two numbered sequels on the UsefulNotes/SuperFamicom. The rest of the series StoppedNumberingSequels in Japan, though the second UsefulNotes/GameBoyAdvance installment was released as ''Fire Pro Wrestling 2'' in the U.S.
* ''VideoGame/ChaseHQ 2'' is actually the fourth game in the series, after ''Special Criminal Investigation'' and ''Super Chase''.
* The ''VideoGame/SuperRobotWars'' franchise includes numerous numbered sequels, though the Japanese titles use Sino-Japanese ordinal numbers. The actual Japanese title of ''VideoGame/SuperRobotWars2'' is ''Dai-2-Ji Super Robot Taisen'', which is analogous to the Japanese name for UsefulNotes/WorldWarII, "Dai-2-Ji Sekai Taisen."
* The sequel to ''VideoGame/{{Jardinains}}'' was simply called ''Jardinains 2!''.
* The ''VideoGame/SaintsRow'' series went all over the place with its sequel numbering. ''VideoGame/SaintsRow2'' used an Arabic numeral, but ''VideoGame/SaintsRowTheThird'' had no numeral at all (playing on the title gang's full name, "Third Street Saints") and ''VideoGame/SaintsRowIV'' switched to a Roman numeral. The switch from Arabic coincided with the shift in tone from the gritty realistic MobWar of the first two games to the DenserAndWackier epicness of the later titles.
* ''VideoGame/PaperMarioTheThousandYearDoor'' had the WorkingTitle of ''Paper Mario 2'', which explains why people usually refer to the game as such.
* After dozens upon dozens of ''Franchise/AngryBirds'' games and spin-offs, we finally have an official ''Angry Birds 2''.
* ''Franchise/AceAttorney'' qualifies, but only in Japan. The main six games are numbered ''Gyakuten Saiban'' 1 through 6 in Japan, but the second installment onwards get different names in Western countries.
** The ''[[VisualNovel/AceAttorneyInvestigationsMilesEdgeworth Ace Attorney Investigations]]'' spin-off series counts as well, with the second installment titled ''Gyakuten Kenji 2''. The FanTranslation follows the precedent set by the main series, giving it the subtitle ''Prosecutor's Path''.
* ''VideoGame/OutRun 2'' was finally released to arcades in 2003, though it was actually the fourth Creator/{{Sega}} UsefulNotes/ArcadeGame to have ''[=OutRun=]'' in the title.
* Sony's [=PlayStation=] line of home consoles: UsefulNotes/PlayStation, UsefulNotes/PlayStation2, UsefulNotes/PlayStation3, UsefulNotes/PlayStation4.

[[folder:Webcomics and Web Animation]]
* WebVideo/TheAdventuresOfSheepAndChicken:Part Three of the first series is titled Part III
* ''WebAnimation/HomestarRunner'' spoofs this with its movie, "Dangeresque 2: This Time, It's Not Dangeresque 1". The end of that e-mail announced "Dangeresque 3: The Criminal Projective" (in 3D). In an e-mail concerning Dangeresque 3, Dangeresque 1 was revealed as "Dangeresque 1: Dangeresque, Too?" (not in 3D).
** Also, in the Halloween cartoon "Three Times Halloween Funjob", Coach Z tells Homestar he's dressed as Kool Moe Dee of the Treacherous Three (and not "Wesley Snakes"), and Homestar remarks "I only saw Treacherous 1 and 2, so I wouldn't know."
** A Halloween cartoon is titled ''Jibblies 2'', although it is pointed out that there was no original ''Jibblies''. Quoth the Strong Sad: "Original? Horror movie? Not these days."
* The ''Webcomic/SluggyFreelance'' Story Arc "KITTEN" was based around parodying horror movie tropes. Naturally, it was given a sequel titled "KITTEN II."

[[folder:Web Originals]]
* ''Roleplay/SurvivalOfTheFittest'', a RP board, is split up into "versions" by [[BigBad Danya]]. Each version takes place on a different island with ~150 characters trying to be the [[KillEmAll last one standing]]. Version 0 refers to the final "test run" which was only shown on an obscure channel, and Version 1 was shown nation-wide (and the first where people started writing). These were followed a year later by Version 2 and another year later by Version 3. The fourth version takes place [[WebcomicTime in 2008.]]
* In the Website/{{Facebook}} app ''VideoGame/RockBandWorld'', the only goal to get one of these is the Scavenger Hunt goal "Rock Band Petting Zoo". With seventeen songs, "so think of this as the main event to Part 1's opening ceremony."

[[folder:Western Animation]]
* Spoofed in ''WesternAnimation/StevenUniverse''. Three episodes involving Lion as a driving force are titled "Steven's Lion", "Lion 2: The Movie", "Lion 3: Straight to Video", and "Lion 4: Alternate Ending". Despite their titles, the latter three are not {{Sequel Episode}}s to the first, the second is not TheMovie, the third is not a direct-to-video special, and the fourth is not a RevisedEnding for another episode. The subtitles actually describe the plot of those particular episodes.

[[folder:Real Life -- Sports]]
* Each UsefulNotes/SuperBowl is known by its Roman numbered ordinal. This began with Super Bowl III in 1969, after the first two were simply known as the "AFL-NFL Championship Game" and later retconned into Super Bowls.
** Except for the 50th Super Bowl in 2016, which the NFL is marketing as Super Bowl ''50'' (not "L"). See [[http://en.wikipedia.org/wiki/Super_Bowl_50#Use_of_the_Arabic_numeral The Other Wiki]] for an explanation.
* The UsefulNotes/OlympicGames are officially referred to by number. The 2016 Summer Olympics will be the Games of the XXXI Olympiad.
** It's worth noticing the ones cancelled due to World Wars still count for the Summer Games, but ''not'' for the Winter Games.
** Makes a certain amount of sense since an olympiad is a measure of time.
** Numbering the Winter Games in the same manner as Summer Games could have become awkward once the IOC changed the Winter Olympic cycle to fall in the middle of an Olympiad (the even-numbered year between Summer Olympics). Since an Olympiad is officially defined as starting on January 1 of a Summer Olympic year, the 25th Olympiad (19921995) had two Winter Games (1992 and 1994).
* In boxing and mixed martial arts, rematches between notable competitors are often numbered, such as Ali-Frazier 2.
* The [[UsefulNotes/MixedMartialArts Ultimate Fighting Championship]] began using numbered sequels after the first event, which was retroactively renamed "UFC 1: The Beginning." Interestingly, there was much fanfare over UFC 100, even though it was actually the 105th UFC event due to the fact that five previous events did not follow the traditional numbering scheme. The smaller Ultimate Fight Night series of events used a numbering scheme until UFN 6, after which they were usually named after their headliners. The Ultimate Fighter reality series is numbered based on season. A new line of free events airing on the Versus channel is set to debut with "UFC Live on Versus 1," a rare instance of a work receiving a number before it has any sequels. Many other mixed martial arts promotions have followed suit by numbering each of their events.
* In rugby league, the Super League of Europe (OK, mostly England, but with one team in France) has officially numbered its seasons with Roman numerals since its creation in 1996. The most season of 2015 will be Super League XX.

[[folder:Real Life -- Other]]
* UsefulNotes/WorldWarII, the "sequel" to the Great War also known as the War to End All Wars that is now commonly referred to as World War I. Of course, there is also the as yet hypothetical WorldWarIII. [[WorldWarWhatever Higher numbered World Wars]] are occasionally referenced in media set far enough into the future.
--> '''Albert Einstein:''' "I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones."
* UsefulNotes/TheCrusades were numbered retroactively by historians, from the First Crusade (1096-99) to the Ninth Crusade (1271-72) and many unnumbered Crusades also.
* The European alliances that were fighting against France during the Revolutionary and Napoleonic Wars were successively numbered coalitions of various countries opposing the expansion of French power. The coterminous military conflicts between the two sides are subsequently also most often referred to as "The War Of the First/Second/etc. Coalition".
* Swedish monarchs are traditionally numbered after an old historical work from the 16th century, it's only that most of the kings mentioned are made-up. So the current swedish king is Charles XVI, but there are only two Charleses before Charles IX, so seven are missing.
* The First Balkan War and Second Balkan War.
* Most operating systems will suggest doing this if you try to move or copy a file somewhere that already has a file with that name in it. Usually the number will be in parentheses.
** Bizarrely, the ''Ocean's Twelve''-''102 Dalmatians'' method crops up in the Linux screen capture app [=KScreenshot=]. Save a screenshot as "Left 4 Dead boomer.png", for example, and the next screenshot you take will suggest you use "Left 5 Dead boomer.png" as its title. Seriously.
* Thinking Machines introduced its first supercomputer, the Connection Machine CM-1, in 1986. A year later, they introduced the higher-performance CM-2. Their next-generation supercomputer, introduced in 1991, was named the CM-5 in order to throw off customers who might have held off on buying a CM-2 if a CM-3 or CM-4 was in the works. The official excuse for this was that they were taking alternate numbers from the Fibonacci series, which would have made the next Connection Machine the CM-13, had one ever been developed.
