Kessen is a strategy game that tells the story of the events that brought feudal Japan out of a century of civil war and installed the Tokugawa Shogunate as the dominant political entity for the next two hundred years. As either Tokugawa Ieyasu or his opponents, you'll engage in real time battles, including Sekigahara, one of the largest and most famous battles in Japanese history. Victory or defeat will steer you down a campaign trail, taking you either through the historical events of the time or down fictional 'what if?' scenarios.
