Thirty-two years ago, the super-simple four-page Rules According to Ral which were designed for Medieval combat were expanded into the thirty-page (approx) Chaos Wars (1987) for fantasy combat. Still a simple rule set by most wargaming standards but complex enough to present tactical options that mitigate dice rolls and remove a fair amount of the luck factor that plagues simpler systems. I picked this up from Wayne's Books through Amazon for about $20 and it included two of the Easy Reference Sheets, a sheet of Unit Stat Cards, and a Fall 1987 War Bulletin. Nice! A few months ago, I got the chance to play using these rules with Michael Shorten and you can read more about that fun time here.
