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 fourth round of releases, we offer "NOBUNAGA’S AMBITION: Bushou Fuunroku," the 4th in this orthodox simulation game series, released in 1990. The theme is "Culture&Technology." Tea ceremonies and the gathering of tea items add a cultural element, while the creation of guns and plated ships express the technology of the time. The game includes 48 countries and over 700 officers.
