In 1982 Enix sponsored a video game programming contest in Japan which brought much of the "Dragon Quest" team together, including creator Yuji Horii. The prize was a trip to the United States and a visit to AppleFest '83 in San Francisco, where Horii discovered the "Wizardry" video game series. The contest winners Koichi Nakamura and Yukinobu Chida, together with Horii, released the Enix NES game "The Portopia Serial Murder Case". Music composer Sugiyama, known for composing jingles and pop songs, was impressed with the group's work and sent a postcard to Enix praising the game. Enix asked him to compose music for some of its games. The group then decided to make a role-playing video game that combined elements from the western RPGs "Wizardry" and "Ultima". Horii wanted to introduce the concept of RPGs to the wider Japanese video game audience. He chose the Famicom because, unlike arcade games, players would not have to worry about spending more money if they got a "game over", and could continue playing from a save point. Horii used the full-screen map of "Ultima" and the battle and statistics-oriented "Wizardry" screens to create the gameplay of "Dragon Quest". "Dragon Ball" creator and manga artist Akira Toriyama, who knew of Horii through the manga magazine "Weekly Shōnen Jump", was commissioned to illustrate the characters and monsters to separate the game from other role-playing games of the time. The primary game designs were conceived by Horii before being handed to Toriyama to re-draw under Horii's supervision. When Horii first created "Dragon Quest" many people doubted that a fantasy series with swords and dungeons, instead of science fiction elements, would become popular in Japan; however, the series has become very popular there. Since then Horii has been the games' scenario director. "Dragon Quest" was Sugiyama's second video game he had composed for, "Wingman 2" being his first. He says it took him five minutes to compose the original opening theme. His musical motifs from the first game have remained relatively intact.
