Shogun: Total War is a turn-based strategy and real-time tactics video game developed by The Creative Assembly and published by Electronic Arts for Microsoft Windows personal computers. Released in June 2000, the game became the debut title in The Creative Assembly's Total War series. Set in Japan during Sengoku jidai—the "Warring States" period from the 15th to the beginning of the 17th century—the game has players adopt the leader of a contemporary Japanese clan, attempt to conquer the nation and claim the position of shōgun. The turn-based aspect of the game focuses on a map of Japan where military force, religion, diplomacy, espionage and economics all influence the player's actions, whilst battles are fought in a 3D real-time mode.

Real-time tactics (RTT) is a subgenre of tactical wargames played in real-time, simulating the considerations and circumstances of operational warfare and military tactics. It is differentiated from real-time strategy gameplay by the lack of classic resource micromanagement and base or unit building, as well as the greater importance of individual units and a focus on complex battlefield tactics.
