About this gameFull description from Steam
To commemorate Kou Shibusawa's 35th anniversary, the "Kou Shibusawa Archives" will be opened in the Steam Store. Here we will revive popular previously released titles. In this seventh round of releases, we offer "NOBUNAGA’S AMBITION: Shoseiroku with Power Up Kit" the enhanced version of the 7th release in the series. In Shoseiroku, the theme is "The Warring States from the viewpoint of a Castle Daimyo." In it, players the land of Japan is shown on a huge tactical map to portray the lord's ability to survey his demesnes from the top of his castle. Both domestic and military activities take place on that one map and players strive to unify the country under their own rule.
