Double Dribble, known in Japan as Exciting Basket (エキサイティング バスケット Ekisaitingu Basuketto?), was the second basketball arcade game developed and released in 1986 by Konami. It was the second basketball arcade game by Konami, following Super Basketball. Much of the game's popularity came from its animation sequences showing basketball players performing slam dunks, as well as The Star-Spangled Banner theme during attract mode, which was the first arcade game to feature the national anthem. These were uncommon in video games at the time of Double Dribble's release. While successful in the arcades, the game became and remained popular and remembered when it was ported to the Nintendo Entertainment System in 1987. Double Dribble was followed by a sequel titled Double Dribble: The Playoff Edition, which was released in 1994 for the Sega Genesis/Mega Drive. A remake titled Double Dribble Fastbreak was released for iOS in 2010, being based mostly on the NES version; however, the animation sequences were ripped from the arcade version.

Downtown is a term primarily used in North America by English speakers to refer to a city's core (or center) or CBD (Central Business District), often in a geographical, commercial, or communal sense. The term is thought to have been coined in New York City, where it was in use by the 1830s to refer to the original town at the southern tip of the island of Manhattan. As the town of New York grew into a city, the only direction it could grow on the island was toward the north, proceeding upriver from the original settlement (the "up" and "down" terminology in turn came from the customary map design in which up was north and down was south). Thus, anything north of the original town became known as "uptown" (Upper Manhattan), while the original town (which was also New York's only major center of business at the time) became known as "downtown" (Lower Manhattan). During the late 19th century, the term was gradually adopted by cities across the United States and Canada to refer to the historical core of the city (which was most often the same as the commercial heart of the city). Notably, it was not included in dictionaries as late as the 1880s. But by the early 1900s, downtown was clearly established as the proper term in American English for a city's central business district.

Dr. Mario (ドクターマリオ, Dokutā Mario?) (Often stylized as D℞. Mario) is a 1990 Mario arcade-style action puzzle video game designed by Gunpei Yokoi and produced by Takahiro Harada. Nintendo developed and published the game for the Nintendo Entertainment System and Game Boy consoles. The game's soundtrack was composed by Hirokazu Tanaka. The game focuses on the player character Mario, who assumes the role of a doctor and is tasked with eradicating deadly viruses. In this falling block puzzle game, the player's objective is to destroy the viruses populating the on-screen playing field by using colored capsules that are dropped into the field. The player manipulates the capsules as they fall so that they are aligned with viruses of matching colors, which removes them from play. The player progresses through the game by eliminating all the viruses on the screen in each level. Dr. Mario received positive reception, appearing on several "Best Nintendo Games of All Time" lists. The game was either ported, remade, or has had a sequel on every Nintendo home console since the NES as well as most portable consoles, including a re-release in 2004 on the Game Boy Advance as part of the Classic NES Series. Modified versions of Dr. Mario were included as minigames in WarioWare, Inc.: Mega Microgames! and Brain Age 2: More Training in Minutes a Day!.

Dragon Ball Z (ドラゴンボールZ(ゼット), Doragon Bōru Zetto, commonly abbreviated as DBZ) is a Japanese anime television series produced by Toei Animation. Dragon Ball Z is the sequel to the Dragon Ball anime and adapts the last 325 chapters of the original 519-chapter Dragon Ball manga series created by Akira Toriyama, that were published from 1988 to 1995 in Weekly Shōnen Jump. Dragon Ball Z first aired in Japan from April 25, 1989 to January 31, 1996 on Fuji TV, before being dubbed in several territories around the world, including the United States, Australia, Europe, India, and Latin America. Dragon Ball Z details the continuing adventure of Goku as a young adult and father to his son Gohan. After learning he is a Saiyan, Goku dies and is revived after training in the afterlife under the god North Kaiō. Goku defends Earth from the Saiyans under Vegeta, and leaves Earth to ultimately defeat them again and the galactic tyrant Frieza. Three years later an evil life form called Cell holds a fighting tournament to decide the fate of the Earth. Goku sacrifices his own life and Gohan avenges his father by defeating Cell. Seven years later, Goku is revived and quickly drawn into a fight against a magical being named Majin Buu. After numerous battles, destruction and recreation of the Earth, Goku destroys Buu with the energy of everyone on Earth making a very powerful attack called "Spirit Bomb". Due to the success of the anime in America, the manga comprising Dragon Ball Z was released by Viz Media under the title Dragon Ball Z. Additional manga works, called animanga, were released which adapt the animation to manga form. Dragon Ball Z's popularity has spawned numerous releases which have come to represent the majority of content in the Dragon Ball universe; including 14 movies and 57 video games and a host of soundtracks stemming from this material. Dragon Ball Z remains a cultural icon through numerous adaptations, including a remastered broadcast as Dragon Ball Kai from 2009 to 2011 and from 2014 onwards.

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.
