Sword of the Samurai (1989)

A duel can settle an insult, but your family’s standing also depends on land, alliances, and whether someone can inherit when you die. MicroProse’s 1989 game moves between quick sword fights and decisions whose consequences may take a generation to see. It is a good introduction to the sort of DOS strategy game that keeps changing what it asks you to do. The GOG edition runs in DOSBox.
