Medieval: Total War Trailer 1

This 2002 main game blends turn-based strategy on a campaign map with massive real-time tactical battles across the Middle Ages. You manage empire-building through diplomacy, trade, and espionage while commanding armies in large-scale combat. A key feature is the influence of religion (Muslim, Orthodox, Christian) on allegiances, requiring players to manage papal demands or risk internal instability and rebellion across four centuries of dynastic rule.
