Nobunaga's Ambition: Sphere of Influence KOEI TECMO AMERICA CORP.



Hailed as one of the best installments in the franchises history, this extremely intricate, deep, and meticulous strategy game is set against a backdrop of a fragmented nation. Players take the mantle of a Daimyo, a feudal lord of the Sengoku era (15th-16th century Japan), and fight for the great ideal of uniting the war-ridden country under one rule, thus becoming the first Shogun.

This title, centering around creating a realistic, dynamic, and dramatic playing experience, requires a high level of concentration and skill as players will need to master three key verticals in order to become a well-rounded ruler and successfully beat the game: Creation, Diplomacy and War.

In Creation, players must strengthen their clans standing, and deal with everyday issues like building farms & roads, growing the economy, entering trade agreements with neighbouring fiefs, etc.

Diplomacy is a playground for cultivating diplomatic relationships, employing spies, creating alliances, gaining the loyalty of subordinate officers, and growing in strength via marriage, oaths of fealty and treaties.

Finally, to succeed in War, players must train troops, level up officers according to the clans needs, fortify defenses, strategically position armies, and attack (or defend) to further their goals and grow their dominion.

Choosing to play either as a historical personality or a uniquely edited character, Nobunagas Ambition: Sphere of Influence is both a full scale historical simulation and a bona fide strategy title, and offers an extremely wide pallet of choices for the player to shape the world as they please.
