"Romance of the Three Kingdoms (三國志 Sangokushi, lit. "Records of Three Empires") is a computer and video game that originated from Japan. It is a series of turn-based computerized wargames by Koei. Eleven editions of the series have been published in Japan and Chinese-speaking countries in East Asia. The Japanese title of the game is Sangokushi.
The games are based on the events of the Romance of the Three Kingdoms and the Records of Three Kingdoms in China during the 2nd and 3rd centuries.
Gameplay mainly revolves around managing numerical statistics, each representing an attribute of a city or character. For example, a city will have statistics indicating the amount of food stored within its walls, its vulnerability to disasters such as floods and earthquakes, how content the people are, and so forth. Characters have statistics to reflect his/her fighting prowess, intelligence and loyalty to his/her ruler among other attributes. Most players will spend more time on improving these statistics than waging war against neighboring territories, as the artificial intelligence of the other rulers tends to be peaceful unless the player attacks them first, or unless they have reached a point of the story where war must break out. Even during such situations, rampant warfare is discouraged, particularly during winter."
