It is a real-time tactics game set in feudal Japan, focusing upon a conflict between the eastern Tokugawa clan and western Toyotomi clan (with Ishida Mitsunari as the Toyotomi's guardian and protector) shogunates at the end of Sengoku Jidai. Tokugawa Ieyasu served as the primary representative for the Eastern forces where the Western army changed leaders based on the results of select key battles. (wikipedia.org).
