Archworld
From Wikipedia, the free encyclopedia

Archworld is a system of wargame rules for fantasy and medieval miniatures combat that was published by Fantasy Games Unlimited FGU in 1977.
The combat rules in the original fantasy role-playing game Dungeons & Dragons, published by TSR in 1974, used the traditional wargaming combat system from the previously published Chainmail, which measured movement and distances on a sand table in inches. Later editions made the use of miniatures optional,[1] and assumed most players would make D&D a game of the imagination, where players would simply describe what their player characters were doing. However, by 1977, the use of 25 mm fantasy miniatures was becoming popular. In recognition of that, FGU published a set of combat rules for miniatures using a 1" hex grid rather than sand-table measurements. The early versions of D&D expected heroes would attract bands of henchmen, so the Archworld combat system provides for both single figures as well as figures representing groups of twenty henchmen or soldiers.[2]
The movement system is based on numbers of paces, with one pace equalling 2.5 feet, and one hex equalling 25 feet (ten paces). The book also includes rules for medieval naval combat, and provides details of a fantasy campaign world, with a map of Archworld included.
