Nobunaga's Ambition

Nobunaga's Ambition (信長の野望, Nobunaga no Yabo) is a turn-based strategy video game released in 1988. It is part of a series of loosely adapted historical simulations produced by the Japanese video game developer Koei.

Overview
Nobunaga's Ambition takes place during the Sengoku period of feudal Japan. As the title suggests, 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 daimyo of the time. The online MMORPG includes magic for the players and mythological beasts for them to slay, one of which includes the snake beast, Yamata no Orochi.

Recently, games have also started to include Western settlers and various fictional figures who were said to be active during the time such as the Sanada Ten Braves. Other guest characters from past installments include figures from people from the Aynu culture, a few of the Forty-seven Ronin, Mongols from Genghis Khan's time, and figures from the Bakumatsu period in Japan, Sakamoto Ryoma and Kondo Isami. Characters from Romance of the Three Kingdoms also crossover in select games.
