Nobunaga's Ambition is a historical turn-based strategy game set in 16th century Japan during its Sengoku period. The nation was fragmented into numerous feudal states ruled by powerful daimyos, each vying for power and control. Players take on the role of Nobunaga Oda or other ambitious daimyos to conquer Japan and become the Shogun.
The game features a unique blend of strategy and character development. Players can choose from 17 regions or the larger 50-scenario mode, selecting a daimyo with attributes in six categories: Age, Health, Ambition, Luck, Charm, and IQ. As the game progresses, these values change based on events and outcomes, adding depth to the gameplay.
Gameplay revolves around issuing commands from a menu each turn, including recruiting soldiers, training the army, buying weapons, improving peasant morale, forming alliances, or hiring ninjas for covert operations. When conflict arises, battles are fought in an overhead-view hex battle map, with players taking turns moving units and issuing orders to defeat enemy forces or force surrender.
