Sword of Aragon

Regarded by many wargamers as THE best fantasy wargame ever made, SSI’s Sword of Aragon is the first 4X game and a true precursor of later classics such as Conquered Kingdoms or SSI’s own Fantasy General. Set in the Aragonian Empire, you are heir to the late Duke of Aladda, and your task is to once again extend Aladda's dominion and eventually crown yourself king in Tetrada. Executing your father's will properly means raising and equipping an army, then venturing forth to do battle against the dastardly foes threatening Aladda and its surroundings. Your success in Sword of Aragon depends on careful allocation of precious resources, astute military planning, and deft combat maneuvers. Knights, priests, warriors, mages, rangers, cavalry, infantry, and bowmen are some of the units you can recruit, and in true AD&D fashion, you can equip them with different armor types. Nothing in the game will strike anyone today as a big deal, but back in 1989 it was a revolutionary title that attracted many non-wargamers to the genre. Excellent AI and addictive gameplay help Sword of Aragon remain one of the most playable and replayable fantasy wargames ever. Two thumbs up!
