Dragon Quest (Japanese: ドラゴンクエスト Hepburn: Doragon Kuesuto?), published as Dragon Warrior in North America until 2005,[Note 1] is a series of internationally best-selling console role-playing video game (RPG) titles created by Yuji Horii and his studio, Armor Project. The series is published by Square Enix (formerly Enix), with localized versions of later installments for the Nintendo DS (NDS) being published by Nintendo outside of Japan. The first title was published in 1986 and there are currently ten main-series titles and numerous spin-off games. Nearly every game in the main series has either an anime or manga adaptation, or both. The series has had a significant impact on the development of console RPGs, and introduced a number of features to the genre. Installments of the series have appeared on MSX computers, Nintendo Entertainment System, Super Nintendo Entertainment System, Game Boy Color, Game Boy Advance, Nintendo DS, PlayStation, PlayStation 2 and Wii video game consoles, and several models of mobile phones. Each Dragon Quest video game soundtrack is arranged into an orchestral piece and the video game series is the first to have live-action ballet adaptations. Early in the series the Dragon Quest games were released under the title Dragon Warrior in North America to avoid trademark conflict with the pen-and-paper role-playing game DragonQuest. Square Enix did not register the Dragon Quest trademark for use in the United States until 2002. The basic premise of most Dragon Quest titles is to play a hero who is out to save the land from peril at the hands of a powerful evil enemy, with the hero usually accompanied by a group of party members. Common elements persist throughout the series and its spinoff titles: turn-based combat; recurring monsters, including the Slime, which became the series' mascot until the English version of Dragon Quest VIII: Journey of the Cursed King; a text-based menu system;[Note 2] and random encounters (in the main series), until Dragon Quest IX: Sentinels of the Starry Skies. The series is one of the few long-running video game series to have a stable key development team; scenario writer and game designer Yuji Horii, character designer Akira Toriyama and music composer Koichi Sugiyama have handled their respective roles from the beginning of the series. The original concepts, used since the first game, took elements from the western RPGs Wizardry and Ultima. A great deal of care was taken to make the gameplay intuitive so that players could easily start to play the game. The series features a number of religious overtones which were heavily censored in the NES versions. Dragon Quest X is the newest game in the series. It is a massively multiplayer online game, featuring online battles. It has currently been released in Japan on the Wii, Wii U, and Microsoft Windows.

Dragon Scroll (ドラゴンスクロール 甦りし魔竜, lit. "Magic Dragon Scroll Dragon Reborn") is a 1987 video game that was released exclusively in Japan for the Family Computer. The game is non-linear and operates almost like a sandbox game. Many video games helped to influence this video game, including The Legend of Zelda. A large video game world helps to define the complexity of the gameplay. However, most puzzles are impossible for non-Japanese speakers to solve, but a fan-made translation patch has been made available by King Mike Translations in 2008.

Dragon Spirit (ドラゴンスピリット, Doragon Supiritto?) is a 1987 vertical scrolling shooter arcade game released by Namco and Atari Games (in the US). It runs on Namco System 1 hardware, and was later ported to the Amstrad CPC, Commodore Amiga, Commodore 64, DOS, Atari ST, X68000, PC Engine/TurboGrafx-16 and ZX Spectrum platforms.

Dragon Quest (ドラゴンクエスト, Doragon Kuesuto?), known as Dragon Warrior in the USA, is the first role-playing video game (RPG) in the Dragon Quest media franchise. It was developed by Chunsoft for the Family Computer (known in Japan as the Famicom) and published by Enix in Japan in 1986. Dragon Warrior has been ported and remade for several video game platforms, including the MSX, PC-9801, X68000, Super Famicom, Game Boy Color, and mobile phones. A version of the game for Android and iOS has been released in Japan on November 28, 2013. During the game, players control a hero character who is charged with saving the kingdom of Alefgard and rescuing its princess from the antagonistic Dragonlord. Dragon Warrior's story later became the second part in a trilogy that encompasses the first three games in the series. Several anime and manga, which revolved around this overarching plot, were created. Two of the manga take place between the events in Dragon Warrior and its prequel Dragon Warrior III. The game was created by Yuji Horii, who took inspiration from previous RPGs such as Wizardry, Ultima, and his own 1983 title The Portopia Serial Murder Case. Horii wanted to create an RPG which would appeal to a wide audience of people who were unfamiliar with the genre or video games in general, place a greater emphasis than other RPGs on storytelling and emotional involvement, and expose the mainly Western genre to Japan. Manga artist and Dragon Ball creator Akira Toriyama produced the game's artwork and Koichi Sugiyama composed its music. The North American localization released in 1989 featured numerous changes, including battery-backed RAM save games (rather than using a password save system), modified character sprites and pseudo-Elizabethan English style dialog. Dragon Quest was commercially successful in Japan; its release as Dragon Warrior in North America was less favorably received. Later, Western critics noted the game's shortcomings but acknowledged its importance to the genre. Its original pseudo-Elizabethan English script has been praised in many of these reviews. Fan-made ROM hacks were released with substantial changes to the game. The game's sound effects have also been orchestrated, and its music has been performed at numerous concerts. As a whole, Dragon Warrior has been credited with establishing the basic template for the Japanese console RPGs that followed.

Dragon Warrior II, known as Dragon Quest II: Akuryou no Kamigami (ドラゴンクエストII 悪霊の神々?, lit. "Dragon Quest II: Gods of the Evil Spirits") in Japan, is a role-playing video game (RPG) developed by Chunsoft and published by Enix (now known as Square Enix) in 1987 for the Nintendo Entertainment System as a part of the Dragon Quest series. Enix themselves created the American version of Dragon Quest II, publishing the game there in 1990.[3] Dragon Quest II is set 100 years after the events of the first game. The game's story centers on the prince of Midenhall, who is ordered to stop an evil wizard named Hargon after Hargon destroys Moonbrooke Castle. On his adventure, he is accompanied by his two cousins; the prince of Cannock and the princess of Moonbrooke. Dragon Quest II greatly expands on the series formula from the first game by having a larger party, more areas to explore, multiple heroes and enemies in a battle, and a sailing ship. Dragon Warrior II was successful in Japan; the original Famicom version shipped 2.4 million copies. Later, the game was remade for the Super Famicom and the Game Boy Color with Dragon Warrior as Dragon Quest I & II. A version of the game for Android and iOS has been announced for release in Japan in Winter 2014.[2] The third title in the series, Dragon Quest III: And Into the Legend..., was released in 1988 in Japan.[4] Dragon Warrior III is the prequel of the first two games; it follows the ancestor of the main characters, the legendary hero Erdrick;[5] the three games are collectively called "Erdrick's Legend Trilogy".
