An excellent strategy RPG for the Nintendo Entertainment System of the late 80s. It was set in feudal Japan, and each player had a fief to manage and expand by conquest, alliance, and trickery. Details like managing rice production for your troops, several types of military units, natural disasters (woe unto him who gets flooded repeatedly...), battle scenes, and ninja spies made this game a huge time sink, and lots of fun to play at sleepovers until 6am. Named after Oda Nobunaga, a Japanese lord of historic significance.
