Gordian Knot are a set of Ancient tabletop wargame rules for use with stands of figures, with each stand representing a unit. Using stands means they are suited for use with any scale of wargames figures (6mm - 28mm).
The rules include an example battle narrative to illustrate how the rules work, and as well as the usual mechanisms include a scenario or missions generator, an army selection system, and characteristics for generals (for example, your general may be hated, a dreamer, infirm, short-sighted and could be served by an inept staff!).
