About this gameFull description from Steam
"Nobunaga's Ambition: Taishi" is the 15th entry in the historical simulation game series Nobunaga's Ambition. Where a warrior's resolve exceeds their ambition. We offer the grandest warring states experience to all the fans out there! (Resolve System) Each clan is set apart due to their various "Resolves." We will shine a light on the Resolve of each officer, bringing out diversity in the game play and strategies. The simulation AI has evolved, allowing players a greater sense of immersion in fighting more humanlike Daimyo. (New Strategy) The Civil & Diplomatic systems have been revamped. With a variety of elements new to the series, the player's eye for strategy will be tested. The new evolved Civil & Diplomatic systems show greater depths. (Final Battles) Clash during the "Order/Advance phase," where players try to anticipate their enemies' movements. We use a simultaneous plot system to show the fun of anticipating your opponent and real, high tension battles. (Volume) Lots of officers. Over 2,000 officers appearing and a single high definition 3D map. (Historical Drama) We shine a light on the lives of the officers in this best of all historical dramas. We have included many events showing historical events, stories, and even regional folklore.
