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 Quest III: The Seeds of Salvation, known in Japan as Dragon Quest III: Soshite Densetsu e... (ドラゴンクエストIII そして伝説へ… Doragon Kuesuto Surī - Soshite Densetsu e...?, Dragon Quest III: And thus into Legend...) and previously released as Dragon Warrior III in North America, is a role-playing video game developed by Chunsoft and published by Enix (now Square Enix). It is the third installment in the Dragon Quest series (known as Dragon Warrior in North America at the time of its original release) and the first released for the Family Computer (Famicom) in Japan and later for the Nintendo Entertainment System (NES) in North America. The game saw an enhanced remake for the Super Famicom (the Japanese version of the Super NES) in 1996 and the Game Boy Color in 2001, and a port to mobile phones and the Wii in 2009 and 2011. A version of the game for Android and iOS was released in Japan on September 25, 2014, and worldwide on December 4, 2014 as Dragon Quest III: The Seeds of Salvation. It was the first time the game was given an official English subtitle.The first three Dragon Quest games are part of the same story, and Dragon Warrior III is the first game chronologically, as well as the third game that features the hero Erdrick (Loto in some remakes). The story follows "the Hero" who is tasked with saving the world from the archfiend Baramos. Gathering a group of companions into a party, the Hero must travel the world, stopping at various towns and locations, and find his way to the Demon Lord Baramos's lair.

Exerion (エクセリオン, Ekuserion) is a vertical shoot 'em up released by Jaleco in 1983 and licensed to Taito for distribution on the United States. Exerion is a shoot 'em up game featuring parallax effects and inertia simulation, something notable for 1983. The player travels around strange scenarios shooting aliens. The player has two types of guns: fast single shot (limited) or slow double shot (unlimited). In 1984, along with the MSX1 port of the original, a sequel was released titled Exerion II: Zorni for the MSX1, with similar gameplay to the original; there were plans for an NES release of this game, and a prototype was found. In 1987, the game was followed by the semi-sequel called Exerizer.
