Every claim, by mechanic and game

Concept	Nobunaga's Ambition 1986
Action points	A turn is one season, four to a year, and each fief the player rules gives one order per season, so a player with more fiefs gets more orders. Manual Some actions don't use up a fief's order. On the NES, a loan from the merchant leaves the order free; the PC-98 manual says the same of Grant orders for vassal fiefs and of the Other options. Manual
Character aging	Health falls every spring and whenever there is an epidemic, and a daimyo whose health reaches zero dies. A healthier daimyo is less likely to fall ill, and a sick daimyo can't give some commands. Manual Every spring each daimyo grows a year older and every health value drops by one point, and a daimyo whose time has come dies of old age then. High health can lengthen his life. Manual The PC-98 manual says each daimyo's lifespan is fixed in advance and never shown. In spring an old daimyo may die when it runs out, but a high health value can save him. Manual
Commodity trading	The main display shows a current market price, which changes through the year. The PC-98 manual says the year's base rate is set in spring, and that buying rice raises the rice price and selling lowers it. Manual
Dynastic succession	When a neighboring daimyo is killed by peasants or dies of sickness, the game asks the player whether to bid for his land, paying from the home fief's gold. Manual The PC-98 manual says that when a daimyo dies in spring, a newly appearing daimyo may rise to rule his country; otherwise it becomes vacant land and goes to auction. Manual The PC-98 manual says the game is over when the player's daimyo is killed in war or dies at the end of his lifespan, and mentions no heir. With several players, one player's death doesn't end the game, which goes on until all of them have died or one has unified the country. Manual
Random events	Plague can break out in any season. It lowers the daimyo's health, can kill a weak one, and reduces his men. Manual Typhoons come only in summer and lower a fief's rice output; a high dams value limits the damage. Manual
Turn order	The PC-98 manual says every one of the 50 (or 17) countries gives one order each season, one country at a time, in an order that changes at random every season; the season ends when all have given theirs. Manual In battle the defender places its units first, anywhere on the map, and the attacker places its own near the fief it attacked from. Each day the defender gives one command to each of its units, then the attacker does, and a day passes. Manual
