Nobunaga's Ambition
In 1983, Koei released the historical simulation game "Nobunaga's Ambition", where the player takes the role of the historical figure Oda Nobunaga and must conquer, unify and manage the nation of Japan. It combines number crunching, Japanese history, and grand strategy simulation, including elements such as raising taxes and giving rice to prefectures. "Nobunaga's Ambition" went on to define and set the standard for most console simulation games, and has had many sequels, while Koei continued to create other simulation games since, including the "Romance of the Three Kingdoms" series from 1986 and "Bandit Kings of Ancient China" in 1989. That same year, Capcom released a simulation game of their own, "Destiny of an Emperor", also based on Chinese history.
