Nobunaga's Ambition (信長の野望 Nobunaga no Yabō?) is a series of turn-based grand strategy RPG simulation video games. One of the first games in its genre, it was first released in March 1983 by the Japanese video game developer Koei.
Games in the franchise have been released on a variety of gaming platforms, including the NES, Game Boy, Mega Drive, 3DO, SNES, PlayStation, Sega Saturn, PlayStation 2, PlayStation 3, Xbox 360, and the Wii. The title was also released for Macintosh as well as Amiga and computers with DOS-compatibility.
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 daimyos of the time.
The player may choose from four campaign scenarios including: "Battle for the East" (beginning in 1560), "Daimyo Power Struggles" (1560), "Ambition Untamed" (1571) and "Road Towards Unification" (1582). In each scenario, the player must allocate resources to raise a capable military force, provide a productive economy to support both military and civilian expansion and support the peasants in order to sustain their respect and loyalty. Gameplay is taken in turns, with each turn in the map view corresponding to a season and each turn during battle corresponding to a day. The player may achieve victory through numerous means, among which are forcing the enemy to retreat, destroying the enemy command unit, outlasting an invading force, or prolonging battle until the opposing force has exhausted its supplies.
The player can make many choices during the campaign, such as, according to Evan Brooks of Computer Gaming World: "One may transfer soldiers between fiefs, go to war, increase taxes (which causes a decrease in peasant loyalty which may lead to rebellion), transfer rice or gold to another fief, raise the level of flood control (which decreases productivity), make a non-aggression pact or arrange a marriage, cultivate (which increases productivity, but decreases peasant loyalty), use a merchant (to buy/sell rice, borrow funds, or purchase weapons), recruit for the military (soldiers or ninja), train the army (which increases fighting efficiency), spy on a rival, expand a town (which increases taxes collected, but decreases peasant loyalty), give food/rice to peasants/soldiers (to raise morale), steal peasants from rival daimyos, allocate military strength, recuperate (even a daimyo can get sick), turn over a controlled fief to the computer for administration, or pass a turn (hint: when one has no idea of what to do, train the troops.)"
