Romance of the Three Kingdoms (三國志 Sangokushi, lit. "Records of Three Empires") is a computer and video game that originated from Japan in 1985. It is a series of turn-based grand strategy role-playing simulation wargames by Koei. Eleven editions of the series have been published in Japan, Korea, and Chinese-speaking countries in East Asia, as well as several entries in North America.
There are also several spin-offs based on this series, including the more combat oriented Dynasty Warriors and Dynasty Tactics, which is a combination of Dynasty Warriors and Romance of the Three Kingdoms.
Koei also published three biographical tactical role-playing games based on three characters in the series. They are Sangokushi Eiketsuden (Liu Bei), Sangokushi Koumeiden (Zhuge Liang) and Sangokushi Sousouden (Cao Cao).
