Sugiyama's first contact with Enix was by a fan letter he wrote them regarding a PC shogi game in the early 1980s. After Enix's staff overcame the shock of receiving a handwritten postcard from a celebrity of Sugiyama's stature, they were so impressed by his depth of knowledge and appreciation of games that they decided to ask Sugiyama to create music for their games. Sugiyama started composing for the PC-8801, and was working for Enix at the time. His first project with the company was the 1985 game "World Golf". In 1986, he composed for his first major project, "Dragon Quest". His classical score for the game was considered revolutionary for console video game music.
