* ''Film/MissionImpossibleDeadReckoningPartOne'' (2023). The studio then decided [[https://screenrant.com/mission-impossible-8-release-date-delayed-may-2025/ to drop]] the "Deck Reckoning: Part Two" subtitle from the sequel after ''Part One'' underperformed at the box office.

* Manufactured products, often in tech, don't become the "first generation" until there's a second generation model, e.g. the first generation [=iPhone=] which was known as simply the [=iPhone=] until the 3G model came out.

* The original UsefulNotes/PlayStation was [[ProductFacelift remodeled]] as the [=PSOne=], named as such because it was released at the same time as its successor, the UsefulNotes/PlayStation2.

* ''J.R.R. Tolkien's The Lord of the Rings: Volume 1'' for the UsefulNotes/SuperNintendoEntertainmentSystem was to be the first in a series of adaptations of [[Literature/TheLordOfTheRings the books]] in video game form. The first installment bombed, so there was never a ''Volume 2''.
* ''escapeVektor: Chapter 1'' for the UsefulNotes/{{WiiWare}}, ''Chapter 2'' was never released, instead, just ''escapeVektor'' was released for the [[UsefulNotes/Nintendo3DS 3DS eShop]] with all the chapters.
* ''[[VideoGame/MathBlasterInSearchOfSpot Math Blaster Episode 1: In Search of Spot]]'' for {{UsefulNotes/SNES}}, UsefulNotes/SegaGenesis and PC, followed by ''[[VideoGame/MathBlasterSecretOfTheLostCity Math Blaster Episode 2: Secret of the Lost City]]'', only for PC, and also many more ''[[VideoGame/BlasterSeries Blaster]]'' titles, the ''Episode 1'' wasn't even the first in the series.

** ''{{Franchise/Danganronpa}} 1x2 RELOAD'' for the UsefulNotes/PlaystationVita.
** ''VideoGame/MadouMonogatari 1-2-3'' for the UsefulNotes/{{MSX2}} and UsefulNotes/PC98. This was actually the ''original'' release of both, ''Madou Monogatari 1'' and ''3'', since a prototype version of ''2'' was released earlier as a bonus in a special Christmas-themed issue of Compile's ''Disk Station'' magazine. However, ''Madou Monogatari 1'' was the only that had a stand-alone port on all three of the 16-bit consoles (Super Famicom, Mega Drive and PC Engine) in Japan.

** ''VideoGame/AdvanceWars 1+2: Re-Boot Camp'', a combined remake of the two ''Advance Wars'' games released on the UsefulNotes/GameBoyAdvance, for the UsefulNotes/NintendoSwitch.
* Inverted with the UsefulNotes/XboxOne, which is the successor to the UsefulNotes/{{Xbox 360}} and the third generation of the Xbox consoles, not another name/model for the Original UsefulNotes/{{Xbox}}. By the way, the "Original" being capitalized there? That's Microsoft's official {{retronym}} for that console since the release of the Xbox One.
* Inverted with ''VideoGame/Battlefield1'', which is not another name for the original ''VideoGame/{{Battlefield1}}'', but is actually a title set in a [[RuleOfCool liberally-portayed]] UsefulNotes/WorldWarI. The first game of the series was ''VideoGame/Battlefield1942''.

* ''VideoGame/HorizonZeroDawn''[='=]s logo was adjusted in marketing after the announcement of ''VideoGame/HorizonForbiddenWest'', including the dividing line having a roman numeral I in it to match ''Forbidden West''[='=]s II. It even appears when you have the game installed on UsefulNotes/PlayStation5!

* The {{remaster}} of ''VideoGame/TheLastOfUs'' for UsefulNotes/PlayStation5 and PC is titled ''"The Last of Us Part I"'' for consistency with the sequel ''VideoGame/TheLastOfUsPartII''.
* When ''VideoGame/Pikmin2001'' was ported to the UsefulNotes/NintendoSwitch, it was retitled ''Pikmin 1'' in promotional materials and its dashboard icon; the title itself remains unchanged in the game proper.

* The first installment of the ''VideoGame/DragonSlayer'' series, originally developed by Creator/NihonFalcom and released for the [[UsefulNotes/{{PC88}} NEC PC-8801]] in 1984, was ported to the UsefulNotes/GameBoy in 1990 by toy maker Epoch under the title of ''Dragon Slayer I''. Epoch had previously ported ''Dragon Slayer'' to their failed Super Cassette Vision console in 1986 in notably one of the first game cartridges to use battery-backed saves, but the Game Boy port came out long after some of the game's sequels (namely ''VideoGame/{{Faxanadu}}'', ''Romancia'' and ''VideoGame/LegacyOfTheWizard'' on the Famicom/NES and ''Sorcerian'' on the Mega Drive) had been ported to other consoles.

* ''Film/MissionImpossibleDeadReckoningPartOne'' (2023). The studio the decided [[https://screenrant.com/mission-impossible-8-release-date-delayed-may-2025/ to drop]] the "Deck Reckoning: Part Two" subtitle from the following film after ''Part One'' unperformed at the box office.

* ''Film/MissionImpossibleDeadReckoningPartOne'' (2023). ''Part Two'' is set for release the following year.

* UsefulNotes/WorldWarI: it got this name when UsefulNotes/WorldWarII came by, but some people called it the "The First World War" before. However, this can also be interpreted as "There have been many wars, but this is the first ''world'' war." The UsefulNotes/WarOfTheSpanishSuccession had also been called "the first world war" before the big one.
* Almost all monarchs and rulers don't get to become [[KingBobTheNth "the First"]] until there's at least a second. [[UsefulNotes/ThePope Pope John Paul I]], however, did use "the First" in his title, and actually signed his name ''Ioannes Paulus Primus''. In contrast, Pope Francis, the only other pope in a thousand years with an original papal name, won't be Pope Francis I until there's a Francis II.

** The mobile phone version of the original ''VideoGame/MetalGear'' was sold as a bundle with [[VideoGame/MetalGear2 its sequel]] as ''METAL GEAR 1 & 2'' on Yahoo!'s Japanese mobile service.

* The first installment of the ''VideoGame/DragonSlayer'' series, originally developed by Creator/NihonFalcom and released for the [[UsefulNotes/{{PC88}} NEC PC-8801]] in 1984, was ported to the UsefulNotes/GameBoy in 1990 by toy maker Epoch under the title of ''Dragon Slayer I''. Epoch had previously ported ''Dragon Slayer'' to their failed Super Cassette Vision console in 1986 in notably one of the first game cartridges to use battery-backed saves, but the Game Boy port came out long after some of the game's sequels (namely ''VideoGame/{{Faxanadu}}'', 'Romancia'' and ''VideoGame/LegacyOfTheWizard'' on the Famicom/NES and ''Sorcerian'' on the Mega Drive) had been ported to other consoles.

** ''VideoGame/DragonQuest I & II'', released for the Super Famicom and Game Boy Color.

** ''[[VideoGame/{{Yakuza}} Ryu Ga Gotoku 1+2]]'' for the [=PS3=] and Wii U.

* Music/{{Madness}} had ''The Dangermen Sessions, Volume One''. There has been no Volume Two yet, but if they ever do another covers album it's quite likely they'll return to the title.

* Creator/{{Fox}} announced a channel named Fox Sports 1 (as a replacement for Speed Channel). With a number like that, sports fans must wonder if Fox can launch Fox Sports 2. Yes, Fox later announced Fox Sports 2 (as a replacement for extreme-sports channel Fuel TV), and both networks launched on the same day in 2013. (Naming the channel Fox Sports 1 gives it precedence above the regional Fox Sports channels.) They took the idea from sister company Creator/{{Sky}}, which labels its sports nets as ''Sky Sports (number)'', including channels 1-5; the special F1 channel, and Sky Sports News (HQ) are excluded.

* Inverted with the UsefulNotes/XboxOne, which is the successor to the UsefulNotes/{{Xbox 360}} and the third generation of the Xbox consoles, not another name/model for the original UsefulNotes/{{Xbox}}.

* ''VideoGame/HorizonZeroDawn''s logo was adjusted in marketing after the announcement of ''VideoGame/HorizonForbiddenWest'', including the dividing line having a roman numeral I in it to match ''Forbidden West'''s II. It even appears when you have the game installed on UsefulNotes/PlayStation5!

* The {{remaster}} of ''VideoGame/TheLastOfUs'' for UsefulNotes/PlayStation5 and PC is titled ''"The Last of Us: Part I"'' for consistency with the sequel ''VideoGame/TheLastOfUsPartII''.

* ''{{VideoGame/Nightshade}} Part 1: The Claws of Sutekh'', no Part 2 ever made.

Most franchises with NumberedSequels are like this: The first ever made has a title and the sequels just add numbers and/or subtitles in front of the title, like this → "Title", "Title 2", "Title 3", and if it's a prequel, sometimes it's [[EpisodeZeroTheBeginning "Title 0"]].

* Inverted with ''VideoGame/Battlefield1'', which is not another name for the original ''VideoGame/{{Battlefield}}'', but is actually a ''Battlefield'' title set in a [[RuleOfCool liberally-portayed]] UsefulNotes/WorldWarI. The first game of the series was called ''Battlefield 1942''.

* The VideoGameRemake of ''VideoGame/TheLastOfUs'' for UsefulNotes/PlayStation5 and PC is titled ''"The Last of Us: Part I"'' for consistency with the sequel ''VideoGame/TheLastOfUsPartII''.

* 2021's ''Film/{{Dune|2021}}'' is subtitled ''Dune: Part One'' in the closing credits, since it's a case of DividedForAdaptation (though it's been largely advertised without that subtitle). ''Dune: Part Two'' has been greenlit for release in 2023.

* ''VideoGame/TheLegendOfZelda'' was originally released in Japan for Famicom's Disk System add-on in 1986. When the game was re-released as a standard Famicom cartridge in 1993, it was retitled ''Zelda no Densetsu 1''. The game already called itself "''Legend of Zelda 1''" at the end of the second quest, so this wasn't a major stretch.

* ''The Literature/{{Twilight}} Saga: Breaking Dawn Part 1''. Splitting the last book is becoming popular.

* ''Anime/PokemonTheFirstMovie'', the first one of a series of over 20 movies and still counting. Notably, it did not have the "First" in its title in Japan (or most other countries); the decision to include this naming convention in the (informal) North American title was a safe one, though, since [[Anime/Pokemon2000 a second movie]] had been released in Japan months before the first one came to America, [[Anime/Pokemon3 a third one]] was already in development, and the Pokémon franchise was in the height of its popularity, so it was safe to count on the sequels coming to America as well. Either way, the proper English title was ''Mewtwo Strikes Back'' (a direct translation of the Japanese title ''Mewtwo's Counterattack'') which means the whole issue just comes down to the dubbers (not the creators) adding an unnecessary "First Movie" tag to the title.

* ''ESPN Extreme Games'', one of the U.S. launch titles for the original [=PlayStation=], was re-released as ''[=1Xtreme=]'' after Sony's license to use the Creator/{{ESPN}} branding expired (the game's sequel, ''[=2Xtreme=]'', was already released at that point).

* ''VideoGame/StarGladiator Episode I: Final Contact''. The sequel, which was titled ''Star Gladiator 2'' in Japan, was titled ''Plasma Sword'' everywhere else.

* Standard procedure on Website/TVTropes when a series that doesn't qualify for the Franchise namespace shares a name with its first installment is to trope the series at "[=Medium.WorkName=]" and the first installment at "[=Medium.WorkName1=]". The "1" on the latter page is usually removed via Administrivia/{{the custom title system}}, but sometimes nobody bothers.[[note]]In the case of [[NamesTheSame two works with]] [[SimilarlyNamedWorks the same name]], some other disambiguation is used instead, often the release year.[[/note]]

* ''Film/HistoryOfTheWorldPartI'': One example of when a sequel was never made; a sequel is even teased at the end, but it's okay since it was [[{{PlayedForLaughs}} only a joke]] and the producers [[{{SequelSnark}} never intended to make a sequel]] anyway. [[SequelGap Until it was eventually announced in 2021]] that a sequel series, ''History of the World Part II'', would be made for Creator/{{Hulu}}.

* The original UsefulNotes/PlayStation was [[ProductFacelift remodeled]] as the [=PS one=], named as such because it was released at the same time as its successor, the UsefulNotes/PlayStation2.

* Standard procedure on Wiki/TVTropes when a series that doesn't qualify for the Franchise namespace shares a name with its first installment is to trope the series at "[=Medium.WorkName=]" and the first installment at "[=Medium.WorkName1=]".

* 2021's ''Film/{{Dune|2021}}'' is sutbtitled ''Dune Part One'', since it's a case of DividedForAdaptation. ''Part Two'' has been greenlit for release in 2023.
