Nobunaga's Ambition

Nobunaga's Ambition (信長の野望, Nobunaga no Yabō) is a series of turn-based grand strategy role-playing simulation video games.[1] The original game was one of the first in its genre, being released in March 1983 by the Japanese video game developer Koei.[2][3] Nobunaga's Ambition takes place during the Sengoku period of feudal Japan. The player is tasked with achieving the ultimate goal of warlord Oda Nobunaga: the conquest and unification of Japan. Selecting Oda Nobunaga is optional, however, as the player is also able to choose from a variety of other regional daimyōs of the time.
