Basically, this happens when the numbering of sequels
gets really, really
complicated. A Sequel Number Snarl
often occurs when Sequels
start filling up the chronology, but then gets fouled up by the addition of an Oddly Named Sequel
or two (or five...) whose title doesn't
include a number. Reboots
and Alternate Continuities
can make even more of a mess.
A subtrope of Numbered Sequels
open/close all folders
- The Ring series is somewhat baffling.
- A 1995 film, named Ring and rereleased as Ring: Kanzenban
- Hideo Nakata series: Ring, Rasen, Ring 2 (which ignores the events of Rasen) and a prequel Ring 0: Birthday
- American films The Ring, Rings (a short DVD-only film) and The Ring Two
- Korean film The Ring Virus
- The Rambo series goes First Blood, Rambo: First Blood Part II, Rambo III, and then Rambo (also known as John Rambo or Rambo IV in certain countries). Film critic Roger Ebert pointed out that technically, Rambo III should have been entitled Rambo II: First Blood Part III, which, he supposed, would have caused film executives heads to explode in confusion.
- In Italy, Dawn of the Dead was dubbed under the title of Zombi, spawning two unauthorized sequels by local producer Lucio Fulci: Zombi 2 and Zombi 3. In the U.S., Zombi 2 was retitled Zombie and marketed as a standalone movie with no ties to Dawn of the Dead, but Zombi 3 kept its original numbering, making it seemed as if there was another movie in-between. To add further confusion, two unrelated movies by Zombie 3 co-producer Claudio Fragasso were marketed as Zombie sequels in the U.S.: After Death (aka Zombie 4) and Killing Birds (aka Zombie 5). In the U.K., all four of these movies were released under the title Zombie Flesh Eaters title and were numbered appropriately.
Live Action TV
- Power Rangers gained a bit of this in terms of season numbers when Disney decided to Re Cut part of the first season. Officially, the Re Cut is Season 18, but fans are reluctant to name glorified reruns as a full season and generally consider the following span of new episodes, Power Rangers Samurai, as the actual Season 18.
- Samurai itself was stretched over two years, with the second half retitled Power Rangers Super Samurai, leaving fans unsure whether to count it as one two-year season or two one-year seasons.
- And then there's Power Rangers Megaforce. It was first declared to be a two-year series, appearing to be the same situation as Samurai. But then it came out that Megaforce's second year would adapt material from two Super Sentai series instead of just one, complicating matters. We'll have to wait until it actually airs to see how this is going to play out.
- Long before these, there was Mighty Morphin' Alien Rangers, a transitional period between the third season of Mighty Morphin' Power Rangers and Power Rangers Zeo. It's commonly considered Season 3b, being too short to be a season in itself and sharing enough with Mighty Morphin' S3 to be lumped in with it.
- Super Sentai itself also underwent a similar situation. The first two Sentai shows, Himitsu Sentai Goranger and J.A.K.Q. Dengekitai, which Toei co-produced with Ishinomori Production, were not counted among the later Super Sentai shows that Toei produced independently starting with Battle Fever J. As a result, the premiere of Kousoku Sentai Turboranger served as the tenth anniversary of the series, while Gosei Sentai Dairanger was originally considered the fifteenth series. Somewhere along the lines, Goranger and J.A.K.Q. were retroactively added to the franchise's count, making the earlier anniversary shows before their inclusion seem odd in retrospect.
- The Kamen Rider franchise has a similar issue, not with the number of shows, but with the official number of main Riders:
- The first Kamen Rider series had two main Riders: Rider 1 and Rider 2. Simple enough.
- The second series, Kamen Rider V3, featured a secondary character named Riderman, a villain who underwent a Heel-Face Turn. Despite the fact that Riderman was not a main character, he shows up in many of the subsequent crossover movies and specials as the fourth main Rider.
- Kamen Rider Stronger, the seventh Rider (and fifth series), had a female sidekick named Tackle. Unlike Riderman though, she is not counted as an official Rider.
- The main riders of the ninth and tenth series, Kamen Rider Black and Kamen Rider Black RX, were originally counted as one Rider since they were different alter-egos of the same character (RX being an upgraded form of the original Black). Thus, RX was counted as the eleventh Rider when the older Riders guest-starred in his show. However, Black and RX have been counted as separate characters ever since RX guest-starred in a two-part episode of Kamen Rider Decade where he teamed up with an alternate universe version of himself who retained his original Black form.
- All of the Rider shows from Kamen Rider Agito and onward had numerous secondary Riders (including movie-exclusive characters) in addition to the titular protagonistsnote . Kamen Rider Decade established the official number of Riders by counting all of the Riders from Rider 1 to J (with Black and RX being established as separate individuals at this point) and counting only the titular Riders from Kamen Rider Kuuga and onward.
- The official count leaves out the alternate versions of the first three Riders who were in the reboot movies (The First and The Next), as well as Kamen Rider G (a Rider created for a one-off parody).
- The Traveling Wilburys named their first album Traveling Wilburys Vol. 1, and their second album Traveling Wilburys Vol. 3 — either as a joke, or to reference their involvement in the charity album Nobody's Child: Romanian Angel Appeal, which featured a track by the Wilburys, as well as two George Harrison songs, as a supposed Vol. 2.
- Chickenfoot's second album is Chickenfoot III to spoof Sophomore Slump.
- The original 1984 version of "Do They Know It's Christmas?" was performed by a Super Group named Band Aid. A cover was made in 1989, whose supergroup was called Band Aid II. However, when a second cover was made in 2004, the supergroup was called Band Aid 20.
- Windows 7. In the software numbering, it's 6.1. Going on major design changes, it is the seventh iteration (NT/95/98/ME being the fourth, 2000/XP being the fifth, Vista being the sixth). But as far as major releases go, it's the ninth (NT/95, 98, 2000/ME, etc).
- This has continued with Windows 8 (software number: 6.2) and Windows 8.1 (6.3).
- The various Dungeons and Dragons editions are titled Dungeons and Dragons, The Dungeons and Dragons Basic Set, Advanced Dungeons and Dragons, Basic Dungeons and Dragons, Advanced Dungeons and Dragons Second Edition, Dungeons and Dragons 3rd Edition, Dungeons and Dragons Revised Edition (referred to as D&D 3.5 by the fans and the publisher), Dungeons and Dragons 4th Edition, Dungeons and Dragons Essentials, and the upcoming D&D Next, whose unofficial title is Dungeons and Dragons 5th Edition, despite actually being the 10th version of the game.
- Silent Hill had three numbered sequels, a prequel (Origins/Zero), a subtitled sequel (Homecoming), and a reimagining of the first (Shattered Memories). The next, Downpour, was slated to be released as 8 until someone realized the problem.
- Super Metroid and Metroid Fusion were called "Metroid 3" and "Metroid 4" respectively in their opening sequences. Metroid Prime came out the same time as Fusion, and was intended to be just an aside between the original and Return of Samus. But then the Prime series was a runaway success, creating 2 sequels and 2 spinoff titles. And then, there's Metroid: Other M, an interquel between Super and Fusion, that came out in 2010. This may prompt Nintendo to drop the classic system of numbering if the 2D sequel to Fusion ever comes out.
- Street Fighter, which was released in the order I-II-Alpha-III-IV. Chronologically, it's I-Alpha-II-IV-III.
- Then there's the Street Fighter EX series, a polygonal offshoot of Street Fighter II. In terms of plot, the original game was intended to be a side-story set during the events of II, but since the series was developed by Arika (who own the rights to the new characters introduced in the series), it evolved into its own continuity instead.
- Final Fantasy IV was originally released in America as II, and Final Fantasy VI as III. Synchronising the sequels as of VII confused Americans briefly, but the numbering has caught on.
- StarCraft was initially released on 31 March 1998. By 2009 the franchise included various novels, add-ons, etc., as well as a major Expansion Pack, Brood War. When Starcraft II came out in 2010, there was a noticeable Double Take by some fans at the fact that it was "only" the first sequel.
- Similarly, the Homeworld franchise consists of three major installments, Homeworld (1999), Homeworld: Cataclysm (2000), and Homeworld 2 (2003)
- Call of Duty had its fourth game named Call Of Duty 4: Modern Warfare. Its sequels are named Modern Warfare 2 and Modern Warfare 3. Then there's Call of Duty: Black Ops, which is arguably a spin-off from Modern Warfare, but isn't given the Modern Warfare tagline.
- The Gorky series began with Gorky 17 (also known as Odium), then Gorky Zero and then Gorky 02.
- While officially titled simply Mortal Kombat, the 2011 reboot of the series is considered by developer Netherrealm Studios to be the ninth proper fighting game installment in the franchise, counting the earlier crossover game Mortal Kombat vs. DC Universe as the eighth. However, the sequel to it, which would be Mortal Kombat 10 under that numbering scheme, is currently in development under the working title "Mortal Kombat 2" (or as Ed Boon jokingly put it, "Mortal Kombat 10: We Lost Count"). And one could be easily forgiven for mistaking Deadly Alliance, Deception, and Armageddon for spin-offs instead of the fifth, sixth, and seventh entries in the main series respectively. The sequel to MK9 would later be officially titled Mortal Kombat X.
- The Legacy of Kain series started out with Blood Omen: Legacy of Kain. The sequel shifted the subtitle to the forefront and was titled Legacy of Kain: Soul Reaver. This was followed by Legacy of Kain: Soul Reaver 2 and then by Legacy of Kain: Blood Omen 2, the reasoning being that they were sub-series, the Blood Omen games featuring Kain as protagonist and the Soul Reaver games following Raziel. The developers finally did away with the "numbered sub-series" idea when they released the fifth and currently final game titled Legacy of Kain: Defiance which follows both.
- The Ace Combat series contains six numbered games (of which 1 and 2 weren't originally part of the main continuity, and 3 is set after 04, 5, and 6) and five oddly-numbered ones: Advance (prequel to 3), Zero (prequel to the entire series and, more specifically, 5), X (released before 6 but set after it), Xi (interquel to X), and X2 (which was eventually stripped of the "number" because it had nothing to do with X except the platform). Thankfully, Namco Stopped Numbering Sequels at Ace Combat: Assault Horizon.
- An Older Than the NES example of this trope is Atari's Sprint series of arcade games. Sprint 2 started the series in 1976, followed by Sprint 4, Sprint 8, Sprint One (switching from Arabic numerals to words), Super Sprint, Championship Sprint, and finally Badlands (which is Sprint in a post-apocalypse setting). The confusing thing is that the numbers in the first four Sprint titles do not indicate the game's order in the series. It actually indicates how many human players can race at the same time. So Sprint One got its name for being a one player game, even though it was the fourth in the series chronologically.
- The first game in the Gex trilogy is simply called Gex, and the last one is called Gex 3: Deep Cover Gecko, but the second game is called Gex: Enter the Gecko, no "2" involved.
- The Battlefield series has this. Battlefield 2 was actually the third installment, for instance (which makes some sense; Battlefield Vietnam wasn't as well-received as 1942) . Battlefield 3, on the other hand, is at the very least the eleventh game in the series.
- Resident Evil had its first three numbered installments on the PlayStation, which were then followed by Resident Evil: Code: Veronica on the Dreamcast. Despite not being a numbered installment (a result of the game originally being designed as an exclusive before it got ported to other platforms), Code: Veronica is considered a main title, not only continuing the story from where Resident Evil 2 left off, but actually brought back Albert Wesker as the main antagonist after he was killed off in the original game. The numbered series would move onto the GameCube with a remake of the original (along with ports of the previous sequels), Resident Evil 0 (a prequel) and Resident Evil 4 before going for multiplatform releases from the get-go with Resident Evil 5.
- The arcade version of Contra was followed by a solo sequel titled Super Contra and both games were eventually remade for the NES (the latter being shortened to Super C). The NES games were followed by an SNES sequel titled Contra III: The Alien Wars and all subsequent sequels were left unnumbered until the release of Contra 4 for the Nintendo DS, which was actually the eleventh (non-port) installment in the series and an interquel set between Contra III and Contra Hard Corps. To add further confusion, Contra III was actually the fourth game, since there was a Game Boy game titled Operation C released between Super C and Contra III (which was likely not counted at the time since it was a portable release).
- Note that this was never much of an issue in Japan, where none of the Contra sequels were numbered: Contra III was originally titled Contra Spirits and when Contra 4 was localized there, it was retitled Contra: Dual Spirits.
- The original Shinobi was released for the arcades in 1987, which was followed by two separately-developed sequels in 1989: an arcade sequel titled Shadow Dancer, which featured the same play mechanics as the first game (but with the addition of a canine companion); and a sequel for the Sega Genesis titled The Revenge of Shinobi, which featured completely different play mechanics from the arcade games (with a few elements borrowed from the Master System version of the first game, such as a health gauge and multiple ninjutsu spells). The Genesis later received two additional Shinobi games in the forms of Shadow Dancer: The Secret of Shinobi in 1991 (a remake of the arcade Shadow Dancer with the same play mechanics, but with different stages) and Shinobi III: Return of the Ninja Master in 1993 (the true sequel to The Revenge of Shinobi)note . To add further confusion, there was also a Master System-exclusive sequel released in Europe and Brazil titled The Cyber Shinobi: Shinobi Part II.
- The Wonder Boy sequels consist of Wonder Boy In Monster Land (aka Super Wonder Boy: Monster World), Wonder Boy III Monster Lair, Wonder Boy III: The Dragon's Trap (aka Monster World II), Wonder Boy In Monster World (aka Wonder Boy V: Monster World III) and Monster World IV.
- Most of these alternate titles were the result of the games being retitled in different regions, but even in Japan the Sega Mark III ports of the first two arcade games were released under different names as well (the original Wonder Boy was retitled Super Wonder Boy and Wonder Boy: Monster Land became Super Wonder Boy: Monster World).
- Monster Lair (the third arcade game) and Dragon's Trap (a Master System game) were developed and released almost at the same time, resulting in two different games being titled Wonder Boy III. To make matters more confusing, the Japanese version of Dragon's Trap, Monster World II, wasn't even released until a later Game Gear port, a few months after its own sequel, Monster World III, was released on the Mega Drive. Yes, a Japanese video game series experienced a Sequel First syndrome in its own native country.
- Sonic the Hedgehog is starting to get like this. Officially, it goes Sonic the Hedgehog (released 1991), Sonic 2 (1992), Sonic 3 (1994), Sonic & Knuckles (1994) which is an expansion of Sonic 3, Sonic CD (1993), Sonic 4 Ep. I (2010), and then Sonic 4 Ep. II (2012).
- Sonic CD isn't part of the classic Genesis Sonic series despite being tied to Sonic 4 Ep. II's plot, and Sonic & Knuckles is Sonic 3 Ep. II.
- There's also the Dreamcast games Sonic Adventure (ported to the GameCube as Sonic Adventure DX), followed by Sonic Adventure 2 (ported to the GameCube as Sonic Adventure 2: Battle, not to be confused with the Game Boy Advance game Sonic Battle). Storylines from this series continue into the multiplatform releases of Sonic Heroes, and then further into Shadow the Hedgehog.
- There's also Sonic 3D Blast, which was renamed Sonic 3D: Flickies' Island in Europe, which has no direct connection to any other game, not in the least Sonic Blast for the Game Gear.
- Assassin's Creed seems to be heading down this road. The first game was simply Assassins Creed, the sequel was Assassin's Creed II, followed by Assassin's Creed: Brotherhood and Assassin's Creed: Revelations. It then went back to numbered sequels with Assassin's Creed III, which is the fifth game. The rule is that a numbered sequel means a new historical protagonist and setting, while an unnumbered one continues from the last. That's not counting the spin-offs.
- The arcade sequels to OutRun consist of Turbo Out Run (1989), Out Runners (1993), Out Run 2 (2003), Out Run 2 SP (2004) and Out Run 2 SP SDX (2006).
- Double Dragon V: The Shadow Falls is a fighting game spin-off of Double Dragon that featured character from the Double Dragon animated series. While there was never an official "Double Dragon IV", Double Dragon V seems to be counting the SNES-exclusive Super Double Dragon (aka Return of Double Dragon) as the fourth game in the main series. Whether anyone considers Double Dragon V to be a true Double Dragon sequel is a whole 'nother debate (since it's a game of a completely different genre developed by Leland Interactive without Technos' involvement and with little resemblance to the previous games).
- Bubble Bobble (originally released for the arcades in 1986) was followed by numerous sequels such as Rainbow Islands: The Story of Bubble Bobble 2 (a 1987 arcade sequel that played nothing like the first game), Parasol Stars: The Story of Bubble Bobble III (a TurboGrafx-16 sequel to Rainbow Islands released in 1991), Bubble Bobble Part 2 (an NES sequel to the original game released in 1993), Bubble Symphony (the third arcade game in the series, released in 1994 and also known as Bubble Bobble II in North America) and Bubble Memories: The Story of Bubble Bobble III (the last game in the main series, released for the arcades in 1996)
- Tatakae Genshijin 3, the third game in the series and the second one to star Joe & Mac (the protagonists of the original game) is known as Joe & Mac 2 in the US and Joe & Mac 3 in Europe (note that there was a Joe & Mac Returns released around the same time, but it was an arcade game, whereas Joe & Mac 2/3 is an SNES game). For those curious, Tatakae Genshijin 2 was Congo's Caper.
- Grand Theft Auto... hoo, boy. It goes Grand Theft Auto, Grand Theft Auto: London 1969, Grand Theft Auto: London 1961, (the London games actually being mission packs), Grand Theft Auto II, GTA III, GTA: Vice City, GTA: San Andreas, GTA IV, GTA IV: The Lost and Damned, GTA: The Ballad of Gay Tony (the latter two being DLC), and then GTA V. If you include the portable games and Stories games, Grand Theft Auto V is the 15th overall game in the series.
- The Doom sequels consists of Doom II: Hell on Earth, Final Doom (built on the Doom II system), Doom 64 (an N64-exclusive installment in the series), Doom 3, Doom 3: Resurrection of Evil (an expansion of the original Doom 3) and the upcoming Doom 4.
- The Star Wars: Dark Forces series continues the movies' approach at long chains of subtitles. The games include Star Wars: Dark Forces, Star Wars: Dark Forces II - Jedi Knight, Star Wars: Jedi Knight - Mysteries of the Sith (an expansion pack), Star Wars: Jedi Knight II - Jedi Outcast, Star Wars: Jedi Knight - Jedi Academy.
- Serious Sam: The Second Encounter (or "TSE") and Serious Sam 2 (sometimes referred to as "SS2"" or "II") are actually two different games. The former is a Mission Pack Sequel to the original, while the latter is a completely new installmentóreleased well after The Second Encounterówith its own art style, setting and story line. Both of these were followed by Serious Sam 3: BFE ("Before the First Encounter") a prequel to the original game (referred heretofore as "TFE", or "The First Encounter"). And that's not counting Serious Sam HD and Serious Sam: The Second Counter HD which are Updated Rereleases of TFE and TSE, respectively.
- The main canonical games in the Metal Gear franchise, known collectively as the "Metal Gear Saga", consists of the original MSX2 games, Metal Gear and Metal Gear 2: Solid Snake, the original Metal Gear Solid (which was originally titled "Metal Gear 3" during its early planning), its numbered sequels (Metal Gear Solid 2: Sons of Liberty, Metal Gear Solid 3: Snake Eater and Metal Gear Solid 4: Guns of the Patriots), the PSP game Metal Gear Solid: Peace Walker (originally considered "Metal Gear Solid 5" during its development) and the upcoming Metal Gear Solid V: The Phantom Pain. There's also Metal Gear Solid: Portable Ops, a predecessor to Peace Walker not directed by Kojima, Metal Gear Rising: Revengeance, a spin-off starring Raiden, and other sequels and spin-offs not part of the main continuity (Snake's Revenge, Metal Gear: Ghost Babel and Metal Gear Ac!d).
- Half-Life started with Half-Life, but then three subsequent games taking place at the same time chronologically that do add plot, Opposing Force, Blue Shift, and Decay, were released. Then we get into Half-Life 2, which is followed by Half-Life 2: Episode 1, despite the fact that it's technically the second part if we count Half-Life 2 as the first HL2 episode. Half-Life 2: Episode 2 is similarly the third part of the HL2 story arc. There's also the bonus level demos Half-Life Uplink and Lost Coast.
- Kingdom Hearts was followed by Kingdom Hearts: Chain of Memories, then Kingdom Hearts II, which is actually the third game. It was then followed by an interquel, Kingdom Hearts: 358/2 Days, a prequel, Kingdom Hearts: Birth by Sleep, and a sequel, Kingdom Hearts Coded. After that came Kingdom Hearts 3D [Dream Drop Distance], which is implied to be followed by Kingdom Hearts III. To simplify, Kingdom Hearts II is the third game and second sequel, and Kingdom Hearts III will be the eighth game and the sixth sequel. It's not too confusing a system when you remember that the numbered games are on consoles, rather than handhelds.
- The Super Mario franchise has two different games titled Super Mario Bros. 2: the original Japanese version (aka Super Mario Bros.: The Lost Levels) and the version that the rest of the world is familiar with (which later saw a release in Japan as Super Mario USA). This was done since Nintendo of America considered Lost Levels to be too much of a rehash, in addition to being too difficult compared to the original, and wanted their own version of Super Mario Bros. 2 to publish in its place (presumably to avoid the conundrum of having to renumber Super Mario Bros. 3 when it came time to localize that game in the west, which is what they would've done had they decided to just skip Lost Levels completely without releasing a substitute game).
- Strictly speaking, Super Mario Land 3: Wario Land and Super Mario World 2: Yoshi's Island weren't really proper sequels, but rather spinoffs of their predecessors, which is why their respective sequels dropped the original titles and went by the subtitle instead (e.g. Wario Land II instead of Super Mario Land 4, Yoshi's Island DS instead of Super Mario World 3). Interestingly, the original Super Mario World was originally going to be titled Super Mario Bros. 4 and this working title was still used on the packaging of the Japanese version (it isn't used in the actual title screen).
- The Super Mario Advance series had its own numbering system, despite the games themselves simply being GBA ports of the NES/SNES titles. This led to the fourth entry of the Advance series having the rather weird title of Super Mario Advance 4: Super Mario Bros. 3. Thankfully, they didn't use the full title of Yoshi's Island, dropping the Super Mario World 2 portion to make room for Super Mario Advance 3 instead.
- The attract sequence of Real Bout Fatal Fury 2: The Newcomers markets it as the "7th Episode of Fatal Fury", the previous ones being Fatal Fury: King of Fighters (first), Fatal Fury 2 (second), Fatal Fury Special (third), Fatal Fury 3: Road to the Final Victory (fourth), Real Bout Fatal Fury (fifth) and Real Bout Fatal Fury Special (sixth). Out of these seven games, only Fatal Fury Special was an upgraded version of the previous game (Fatal Fury 2). The original Real Bout Fatal Fury carries over the character roster from Fatal Fury 3, but has a completely different combat system than the one used in previous games, while Real Bout Special and Real Bout 2 are each substantially different from the last as well. The pattern seems to be that numbered sequels were focused on introducing new characters, while the "Special" entries brought back previously retired characters. But then along came Garou: Mark of the Wolves and wiped the whole slate clean by bringing back only Terry Bogard. Between Real Bout 2 and Garou, there was also Fatal Fury: Wild Ambition, a retelling of the original Fatal Fury with the addition of characters from later titles (plus two newcomers and Ryo Sakazaki, "returning" from Special, as Mr. Karate II), and Fatal Fury: 1st Contact, a portable version of Real Bout 2 for the Neo Geo Pocket Color.
- The MOTHER series is straightforward enough... in Japan. Outside of Japan, MOTHER 2 is the first game released, as Earthbound. However, the first MOTHER game was initially considered for release in the United States, and a nearly-finished prototype to this end, titled "Earth Bound", was found in the late 1990s. For the purposes of keeping things straight, this English version of the game is commonly referred to as "Earthbound Zero". Averted with MOTHER 3, however; very few places call it Earthbound 2, and pretty much everyone calls it by its Japanese title. (Not even being considered for localization probably helped matters there.)
- Guilty Gear started off simple enough, with the first game, and then X and XX (and the latter's many retoolings). But then Guilty Gear XX Accent Core Plus ended up being a plot-wise sequel, and then there was Guilty Gear 2: Overture, and all the X and XX games were declared to be Gaiden Games (albeit in-canon Gaiden Games). Fair enough, but then came the next game in the main continuity: Guilty Gear Xrd.
- The first installment of From Software's first-person dungeon crawler series King's Field was only released in Japan, being a launch game for the original PlayStation over there. As a result, King's Field II dropped the numeral for its western release, while King's Field III was renumbered King's Field II. The fourth entry avoided this whole numbering conundrum somewhat by being titled King's Field: The Ancient City in the U.S. (it was still titled King's Field IV in Japan and Europe).
- The fifth entry of Tecmo's Deception series is titled Deception IV: Blood Ties. This is due to the fact that the fourth game in the series was released in the U.S. under the title of Trapt, which is actually the second game in the Kagero sub-series in Japan (between Kagero: Deception II and Deception IV).
- The Corpse Party series suffers from this. You have the original game, now known as Corpse Party PC-98, and its remakes, which completely revamp the storyline and add the subtitles Blood Covered and Blood Covered... Repeated Fear. There's also a Fan Prequel to PC-98 called Corpse Party Zero. Blood Covered... Repeated Fear got a sequel called Book of Shadows, the final chapter of which provides the title for its upcoming direct sequel, Blood Drive. There's also Corpse Party 2U, a Denser and Wackier side game. Now, even though Blood Drive has yet to be released, another sequel set some time after that called Corpse Party 2 Dead Patient is already out, and it gets a proper number because it's centered on an entirely different cast while being set in the same universe. Whew.
- Apple's iPhone. First we have the iPhone, which is followed by the iPhone 3G, named so because of its 3G network capabilities. Back in 2008 (and still today), people (used to) ask whether there was an iPhone 2G. Since the original iPhone ran on 2G networks, some referred to it as the iPhone 2G. The iPhone 3G was followed by the iPhone 3GS, a phone nearly identical to the iPhone 3G in terms of design, but with a better camera and processor (The "S" stands for speed.). Logically, a lot of people thought the next iPhone would run on 4G networks, and thus would be called the 4G. The next iPhone did not have such functionality, though. Instead, it was named the iPhone 4, since it was the fourth version of the iPhone Apple produced. Logically again, people inferred that the next iPhone would be called the iPhone 5. Wrong again! It's the iPhone 4S, without 4G capabilities (unless you count AT&T's experimental HSPA+ as 4G). Apple's next phone (at long last, with 4G LTE capabilities) was then named the iPhone 5... despite being Apple's sixth-generation iPhone. What will the next phone be called, people wondered. 5G? 5S? 6? The next iPhone actually WAS called the 5S, but it was released alongside another iPhone — The 5C. What's next, the 6S and 6C? Or the 5GS and 5GC?
