Koei have been quietly pumping out this kind of historical strategy simulator for long time now and they tend to fly under the radar here in the west. People fond of importing games may be more well attuned to these games as they often tend to be deftly made, stat-heavy explorations into the turn based strategy genre, a genre dominated by western greats such as XCOM, Civilization, et al. This latest offering gives you devious political backstabbing and espionage set against a grand, beautiful tapestry of Japanese History. Expect lots of sword charges and historically accurate behind-the-scenes scheming, but is it enough to contend with western favourites?"
