And I believe that not only have we managed to make these titles great entry games for those who are new to the Pokémon RPG series, but at the same time, really provide a new and fresh experience that long-time fans of the series will enjoy. So it's really my hope that all sorts of people will give these games a try.

So at Game Freak we're also hard at work on another all-new core series Pokémon RPG, exclusively for Nintendo Switch.''</ref> is a series of role-playing video games released for [[Nintendo]] systems and the primary series of Pokémon games. Its games follow a standard model of the {{player}}'s journey through a specific [[region]] to catch and raise {{OBP|Pokémon|species}}, battle other {{pkmn|Trainer}}s, fight [[Villainous team|crime]], and earn recognition (usually by collecting [[Badge]]s from [[Gym Leader]]s) until they are acknowledged as the [[Pokémon Champion|strongest Trainer]]. The series began with the first installment in the [[Pokémon]] franchise, {{game|Red and Green|s}}, released for the [[Game Boy]] in {{pmin|Japan}} on [[Pokémon Day|February 27]], 1996. Core series games have only been released for {{wp|Handheld game console|handheld systems}}, though this includes the [[Nintendo Switch]], which is both a handheld and a home console.

Counting paired games as a single release, there are currently 22 core series games released in Japanese, 21 in European languages (English, French, Spanish, German, and Italian), 15 in Korean, and 7 in Chinese (both simplified and traditional). Counting each game individually, there are currently 38 core series games released in Japanese, 37 in European languages, 28 in Korean, and 13 in Chinese.

The Pokémon [[World Championships|Video Game Championships]] have been conducted using the core series games since 2010. Prior to this, they were conducted using [[Pokémon Battle Revolution]].{{fact}}

==Terminology==
===Series title===
In English, the core series has officially been referred to as the '''main series''', '''Pokémon RPG series''', or '''core series''' in official marketing materials.<ref name="English names" group="note"/> However, all Western releases of games use the abbreviation ''Pokémon'', regardless of whether they are core series games or spin-off games.

In Japanese, Korean, and formerly in Chinese, the series is called the '''Pocket Monsters Series''' (Japanese: '''ポケットモンスターシリーズ''',<ref>[https://web.archive.org/web/20160917190255/http://www.pokemon.co.jp/game-series/ Game Pocket Monster Series | Pocket Monster Official Site] (archive)</ref><ref>[https://www.pokemon.co.jp/game/ GAME LIST]</ref> Korean: '''포켓몬스터 시리즈''',<ref>[https://web.archive.org/web/20200805135605/https://pokemonkorea.co.kr/?inc=game-game_list&GameGroup=P Pokemon Official Site] (archive)</ref> Chinese: '''精靈寶可夢系列 / 精灵宝可梦系列'''<ref>[https://www.youtube.com/watch?v=CIVoUw0h20w&t=9m30s Nintendo HK Official Youtube channel]: Nintendo SpotLight E3 2017 (附中文字幕), 14 Jun 2017</ref>). On Game Freak's website, it is referred to as the '''main series''' ('''本編シリーズ''') instead.<ref>[https://www.gamefreak.co.jp/works/pokemon/ GAME FREAK official site]</ref> All core series games, except [[Pokémon Legends: Arceus]] and [[Pokémon Legends: Z-A]], contain the full name ''Pocket Monsters'' in their Japanese title, whereas [[side series]] and [[Spin-off Pokémon games|spin-off games]] use the abbreviation ''Pokémon'' instead. While the Japanese releases of the [[Pokémon Stadium series]] use ''Pocket Monsters'' in English subtitles, they use ''Pokémon'' in {{wp|kana}} in their Japanese names.

===Game titles===
====Game versions====
Prior to [[Generation VI]], it was standard for the Western releases of the core series games to include the label "'''Version'''" in their title, such as "Pokémon Red '''Version'''" or "Pokémon Diamond '''Version'''", although this was seldom used by the Japanese releases. The game titles with the word "Version" have also been sometimes written without it in official text, such as "Pokémon Red" or "Pokémon Diamond".

The plural "'''Versions'''" when referring to multiple games has been sometimes used as well:

* ''"The Gold, Silver, and Crystal '''Versions''' of Pokémon ARE compatible with Pokémon Stadium 2™ [...]"'' (manual of Pokémon Crystal, page 1)
* ''"This Game Pak can be linked to either Pokémon Ruby or Sapphire '''Version'''. It CANNOT be linked to the Red, Blue, Yellow, Gold, Silver, or Crystal '''Versions'''."'' (manual of Pokémon Ruby and Sapphire, page 3)

The core series game titles released from Generation VI onwards do not include the word "Version", such as Pokémon X, Pokémon Omega Ruby, etc.

====Remake titles====
{{main|Remake#Terminology|Remake → Terminology}}

The names of remakes of core series games are generally derived from the names of the original source games, with a modifier word attached to the front. For instance, {{game|HeartGold and SoulSilver|s}} are remakes of {{game|Gold and Silver|s}}.

====Italicized game titles====
From [[Generation I]] to {{game|Platinum}}, the Pokémon core series game titles were usually written with no italics in the game manuals and box descriptions. From {{game|HeartGold and SoulSilver|s}} onwards, the titles have been consistently written in italics. For instance:

* "You can migrate Pokémon caught in the Game Boy Advance™ Pokémon series: ''Pokémon Ruby'', ''Sapphire'', ''Emerald'', ''FireRed'', and ''LeafGreen'' versions [...]" (manual of {{game|HeartGold and SoulSilver|s}})
* "Various language versions of ''Pokémon Black 2'', ''Pokémon White 2'', ''Pokémon Black'', and ''Pokémon White'' can communicate, battle, and trade with one another." (manual of Pokémon Black 2 and White 2, page 4)
* "This is ''Pokémon Omega Ruby''. The types and likelihood of Pokémon that will appear differ from ''Pokémon Alpha Sapphire''." (back of the box of [[Pokémon Omega Ruby and Alpha Sapphire|Pokémon Omega Ruby]])

The game titles are also italicized on the [[Pokémon.com]] website. For instance:
* "The launch of ''Pokémon Gold'' and ''Pokémon Silver'' on [[Virtual Console]] has given us the chance to take a second look at some of those classics’ most iconic, fun, and memorable events."<ref>[https://www.pokemon.com/us/strategy/ten-cant-miss-activities-in-johto-and-beyond Ten Can’t Miss Activities in Johto and Beyond - Pokémon.com]</ref>

The game titles are also italicized in the creator messages from the [[Pokémon Adventures]] manga. For instance:

* "The [[Game Boy]] games [[Pokémon Gold and Silver Versions|''Pokémon Gold'' and ''Silver'']] are now on sale!!" ([[Hidenori Kusaka]], volume 3 of Pokémon Adventures)
* "You can play [[Pokémon FireRed and LeafGreen Versions|''Pokémon FireRed'' and ''LeafGreen'']] in all sorts of ways [...]" (Hidenori Kusaka, volume 18 of Pokémon Adventures)

==Classification==
===Content model===
While there are no strict rules that make a game a core series game, and previously assumed rules are continuously broken, the games generally have a similar plot structure and {{cat|Game mechanics|mechanics}}.

The {{player}} begins the game in a small town or city of a given [[region]], having no {{OBP|Pokémon|species}} of their own. Through a course of events, the player receives a [[first partner Pokémon]], usually from the region's [[Pokémon Professor]]; there are almost always three first partner Pokémon to choose from, with one {{t|Grass}} [[type]], one {{t|Fire}} type, and one {{t|Water}} type, and a character who will become the player's [[rival]] will typically choose (or already have) another member of the trio based on the player's choice.

After this point, the player begins to journey across the entire region (which contains several settlements like cities and towns, themselves usually connected by [[route]]), {{pkmn2|caught|capturing}} any [[wild Pokémon]] they choose to, and using a [[party]] they assemble to take on other [[Pokémon Trainer]]s. Most regions have eight [[Gym Leader]]s that the player must defeat in order to obtain a [[Badge]] from each one, though in games set in the [[Alola]] region, the player instead participates in the [[island challenge]], and in [[Pokémon Legends: Arceus]], they defeat five frenzied [[noble Pokémon]]. In addition to repeated interactions with their rival, the player must also stop the plans of a [[villainous team]], which often involve the manipulation of [[Legendary Pokémon]].

After all eight Gym Leaders have been defeated or the island challenge has been completed, the player can enter the [[Pokémon League]], where the {{pkmn|Champion}} of the region awaits challengers. However, a series of Trainers known as the [[Elite Four]] must usually be defeated in succession before the Champion can be fought. The Champion is often introduced prior to the player's Pokémon League challenge, and may aid the player on their adventure. After defeating the Champion, the player becomes a Champion themself, which is usually honored by their entry into the [[Hall of Fame]]. Pokémon Legends: Arceus is the only game in the core series to not feature the Pokémon League in any form.

The player's defeat of the Champion can be considered the ending of the game, as it is followed by the [[credits]] being shown. However, there is always post-game content that the player gains access to after this. Often, there is a post-game plotline and locations and facilities that could not be previously accessed become available. Since {{game|Crystal}}, there is usually at least one facility specifically dedicated to {{pkmn|battle|battling}}. The overarching goal is to obtain many species of Pokémon in order to complete the [[Pokédex]]. In the first two generations, every Pokémon species in the game has to be obtained in order to complete the Pokédex, and the player is awarded a [[diploma]] for achieving this. From [[Generation III]] to [[Generation VI]], there are two separate Pokédexes, each with their own diploma as a reward for completing them: the [[regional Pokédex]], which only contains the Pokémon native to the region the game is set in, and the [[National Pokédex]], which is unlocked in the post-game and contains every Pokémon in the game. Starting in [[Generation VII]], the games only contain a regional Pokédex, the completion of which usually rewards the player with a diploma, while the National Pokédex is confined to companion applications like [[Pokémon Bank]] and [[Pokémon HOME]].

===Release model===
While releases continue to break patterns, the release of core series games tends to follow a pattern.

When a [[generation]] of [[Pokémon games]] begins, a pair of games is always released. These paired versions feature virtually the same storyline as each other, but the [[Version-exclusive Pokémon|available Pokémon]] differ, and some other elements are usually slightly different. This encourages [[Trade|trading]], as it is required in order to complete the [[Pokédex]].

Many generations feature what Game Freak internally calls an '''upper version''' (Japanese: '''{{j|アッパーバージョン}}''' ''upper version'')<ref>[https://www.youtube.com/watch?v=3CldWM5ornc&t=94s Nintendo UK YouTube]: Pokémon Ultra Sun & Pokémon Ultra Moon Introduction – Episode 4 – A new Pokémon adventure awaits, 3 Nov 2017</ref> and what Western fans commonly refer to as a "third version", i.e., a follow-up game or pair of games released after the first games of the generation that takes place in the same [[region]] with added features. These games typically both share and lack certain regional {{OBP|Pokémon|species}} that were available in one or both of the original paired versions; thus, a {{player}} of an upper version must link together with the original pair to complete the regional Pokédex as well. On the contrary, upper versions typically contain certain Pokémon from different regions that are unavailable in the original pair, thus being more helpful in completing the [[National Pokédex]]. Until [[Generation VII]], only a single third version following an original pair was ever released at a time; [[Pokémon Ultra Sun and Ultra Moon]] were the first of these games to be released as a pair. Unlike other generations, [[Generation V]] opted for a sequel story instead, while [[Generation VI]], [[Generation VIII]], and [[Generation IX]] entirely forwent follow-up games set in the same region, the latter two instead providing additional features to the original pair of games via paid {{wp|downloadable content}}.

Sometimes, a secondary set of paired versions that are [[remake]]s of earlier titles may also be released.

===Pokémon===
Most [[generation]]s introduce {{OBP|Pokémon|species}} that [[Evolution|evolve]] into or from previously released Pokémon. [[Legendary Pokémon]] with myths specific to the region are almost always included, and frequently appear in [[Legendary group|duos]] and [[Legendary group|trios]]. Most generations also introduce at least one [[Mythical Pokémon]], which are almost always [[Event Pokémon|event-exclusive]] upon being introduced but may become available through other means in later generations.

In all generations, there are some Pokémon that cannot be encountered until after the {{player}} becomes {{pkmn|Champion}}. These are often Legendary Pokémon, such as {{p|Mewtwo}}. These Pokémon may or may not be part of the game's [[regional Pokédex]].

Before the release of a new generation, new Pokémon are often used to promote the new {{pkmn|games}} by including them in the {{pkmn|anime}} or in [[Spin-off Pokémon games|spin-off games]].<!--If/when [[User:Caciulacdlac/Pokémon that appeared before their generation]] enters the mainspace, provide a link in this paragraph.-->

===Box art===
The box art for each game features one {{OBP|Pokémon|species}} which was introduced in that [[generation]] (or, in the case of [[remake]]s, the generation of the original games). This Pokémon is referred to by fans as a [[game mascot]], and with the exception of [[Kanto]]- and [[Hisui]]-based games, it is always the [[Legendary Pokémon]] available in that game at the climax of the storyline.

In terms of the artwork itself, the international {{game|Red and Blue|s}} and all region releases of the initial paired games of each generation from [[Generation III]] to {{Gen|VII}} use their game mascot's original [[Ken Sugimori]] artwork for their box art, whereas all other core series games use specially made artwork.

The titles in the Japanese games typically use some shade of red and blue for either the characters or outlines of the characters. This is most likely in reference to the first internationally released core games of Pokémon Red and Blue. The DLC Expansion Passes for Pokémon Sword and Shield use green and yellow, likely in reference to both {{game|Red and Green|s}}, along with {{game|Yellow}}.

==List of core series games==
In {{pmin|South Korea}}, only {{game|Gold and Silver|s}} were released prior to the foundation of Nintendo of Korea and Pokémon Korea in 2006. The first core series game release after this was {{game|Diamond and Pearl|s}} in 2008.

In {{pmin|Greater China}}, the first core series game release was [[Pokémon Sun and Moon]] in 2016.

The 2002 trademarks were filed around the same time as trademarks for {{game5|Ruby|Sapphire|Emerald|Diamond|Pearl}}, and are all the English names of minerals written in {{wp|katakana}} ({{wp|topaz}}, {{wp|tourmaline}}, {{wp|amethyst}}, {{wp|Moonstone (gemstone)|moonstone}}, and {{wp|Colored gold#White gold|white gold}}). The 2008 trademarks were filed alongside trademarks for {{game2|Red|Green|Blue}}, and are all the Japanese names of colors written with a single {{wp|kanji}}. The 2009 trademarks were filed alongside trademarks for Black, White, and Scarlet, and are all the English names of colors written in katakana. Of these, {{wp|vermilion}}, {{wp|crimson}}, and {{wp|Scarlet (color)|scarlet}} are shades of red.

{{game|FireRed and LeafGreen|s}} and Pokémon Diamond and Pearl were planned alongside Pokémon Ruby and Sapphire.<ref>[https://www.gameinformer.com/b/features/archive/2017/08/14/why-ruby-and-sapphire-were-the-most-challenging-pokemon-to-make.aspx Game Informer interview from August 14, 2017]</ref> Despite being released after Pokémon FireRed and LeafGreen and before Pokémon Diamond and Pearl, Pokémon Emerald was trademarked earlier than Pokémon Ruby and Sapphire.<ref>[https://www.j-platpat.inpit.go.jp/c1800/TR/JP-2002-050145/26314A9E0BC78B5B0D7F8543A61BB8312D62E79E37F94E8E848334A9E2BD2AD9/40/en Emerald trademark]</ref><ref>[https://www.j-platpat.inpit.go.jp/c1800/TR/JP-2002-060454/F17938D242934C819A212E530954DBD72B7206BDDA3B708142623200C37F6B04/40/en Ruby trademark]</ref><ref>[https://www.j-platpat.inpit.go.jp/c1800/TR/JP-2002-060455/D8C3113D5A2C217CBCD881B0E3F7C0F43725A74E85D4A59F489447EBF2709D8A/40/en Sapphire trademark]</ref>

Contrary to what is sometimes reported, an equivalent to Blue matching the pattern of FireRed and LeafGreen was not trademarked by Nintendo, Creatures, or Game Freak. However, Game Freak's [[Junichi Masuda]] mentioned {{j|「ＷＡＴＥＲ　ＢＬＵＥ」}} in Japanese and "WaterBlue" in English on an August 2004 blog post explaining the company's choice of "FireRed" and "LeafGreen" as both the Japanese and international titles for the remakes of {{game|Red and Green|s}}.<ref>[https://www.gamefreak.co.jp/blog/dir/2004/08/index.html Junichi Masuda's old official blog (Japanese)]</ref><ref>[https://www.gamefreak.co.jp/blog/dir_english/2004/08/index.html Junichi Masuda's old official blog (English)]</ref>

The Delta Emerald trademark has been commonly misreported as "Pokémon Delta Emerald", but this latter name was not trademarked. This might suggest a relation to the [[Delta Episode]] in {{g|Omega Ruby and Alpha Sapphire}}, which features references to Pokémon Emerald.

[[Tsunekazu Ishihara]] and Junichi Masuda have explained why upper version counterparts to {{game|Black and White|s}} or {{g|X and Y}} did not materialize.<ref>[https://www.nintendo.co.jp/ds/interview/irej/vol1/index.html Iwata Asks about Pokémon Black 2 and White 2 (Nintendo)]</ref><ref>[https://iwataasks.nintendo.com/interviews/ds/pokemon-black2-white2/0/0/ Iwata Asks about Pokémon Black 2 and White 2 (Nintendo of America)]</ref><ref>[https://www.nintendo.co.uk/Iwata-Asks/Iwata-Asks-Pokemon-Black-Version-2-and-Pokemon-White-Version-2/Iwata-Asks-Pokemon-Black-Version-2-and-Pokemon-White-Version-2/1-Two-Sequels-Two-Years-Later/1-Two-Sequels-Two-Years-Later-663651.html Iwata Asks about Pokémon Black 2 and White 2 (Nintendo of Europe)]</ref><ref>[https://lavacutcontent.com/masuda-ohmori-pokemon-gray/ Dr. Lava's translation of a Spanish Official Nintendo Magazine interview from late 2016]</ref><ref>[https://old.reddit.com/r/pokemon/comments/6ucln2/ama_with_game_informer_magazine_about_their_trip/dlrpo58/ Reddit AMA by Game Informer on their visit to Game Freak from August 2017]</ref> In the case of the hypothetical Pokémon Gray or Grey version, Game Freak decided to instead develop {{game|Black and White|s 2|Pokémon Black 2 and White 2}} to surprise fans (though Black 2 and White 2 were later considered upper versions in some promotional material for the [[Pokémon Sword and Shield Expansion Pass]]), while the potential game "Pokémon Z" was never planned, with {{g|Sun and Moon}} being designed for the [[Pokémon 20th Anniversary]] as another surprise.

{{wp|Eurogamer}} published several articles which mentioned an alleged port of Pokémon Sun and Moon for the [[Nintendo Switch]] codenamed "Stars" between November 2016 and December 2017.<ref>[https://www.eurogamer.net/nintendo-switch-will-get-pokemon-sun-and-moon-version Eurogamer (November 18, 2016)]</ref><ref>[https://www.eurogamer.net/pokemon-sun-and-moon-sold-nearly-2m-copies-in-three-days-just-in-japan Eurogamer (November 22, 2016)]</ref><ref>[https://www.eurogamer.net/pokemon-sun-and-moon-files-include-unused-buddy-feature Eurogamer (December 6, 2016)]</ref><ref>[https://www.eurogamer.net/sources-nintendo-switch-will-have-gamecube-virtual-console-support Eurogamer (December 7, 2016]</ref><ref>[https://www.eurogamer.net/nintendo-confirms-proper-pokemon-role-player-for-switch Eurogamer (June 13, 2017)]</ref><ref>[https://www.eurogamer.net/so-what-happened-with-pokemon-stars Eurogamer (December 15, 2017)]</ref> Coincidentally, an early June 2017 article describes a "clerical error" by [[The Pokémon Company]], which initially listed {{g|Ultra Sun and Ultra Moon}} as Nintendo Switch titles instead of [[Nintendo 3DS]] titles during their announcement.<ref>[https://www.eurogamer.net/pokken-tournament-headed-to-nintendo-switch Eurogamer (June 6, 2017)]</ref>
