Nobunaga's Ambition

Nobunaga's Ambition (信長の野望, Nobunaga no Yabo) is a turn-based strategy video game series first released in Japan in 1983. It is a series of loosely adapted historical simulations produced by the Japanese video game developer Koei. It features a predominately Japanese voice track though English dubs appear during movie cutscenes. It debuted before Romance of the Three Kingdoms but it hasn't been localized as often.

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 game plays in a similar manner as the Romance of the Three Kingdoms series but has a few distinguishing differences. Unlike the former, the imperial court plays a greater role in deciding the damiyos' fate. If the court favors them, players have the option to name someone an enemy of the state, call a ceasefire, or promote their rank. Players can also raise and train ninja to guard a damiyo's envoy. Since the main map doesn't display the statistics for each general, ninja are used to spy on the enemy and report information on their progress. They can additionally reduce the order of their enemies' lands and disrupt relations between two other regional lords. Asking an officer to defect is a greater gamble than Romance of the Three Kingdoms as the player's envoys risk getting captured by the enemy and may face death if they can't escape. Employing officers may require a monetary fee for their services. Players can nominate their clan's Four Guardian Kings, arrange marriages, or choose to retire the clan's head and pass their leadership to another general.

Battles also take place in real time. Armies fight in a secluded area and are given the objective to defeat, siege, or defend. Storehouses and other fortifications can be taken to fortify the player's food supply. Officers can continue to use skills but performing them doesn't always pause the action on the field. The goal is to either fulfill the objectives given or end the battle within a set time limit. If neither side achieves victory, the battle is declared a draw. Iron Triangle continues the real time element but has battles take place on the overworld map, visually resembling the 3D map layout in Romance of the Three Kingdoms XI. The newest title will also include options to reshape the landscape surrounding the player's cities and include "what if?" versions of certain characters. These versions play on theories and famous fictional interpretations known in Japan such as a female Kenshin and the Kagemusha Ieyasu.

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 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. 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.
