Majestic 12 games offers these demo rules for their Ares fantasy skirmish miniature wargames system. They explain:
ARES: Miniatures Wargaming System is a complete skirmish-level fantasy game. But it is also much more. The flexibility of the system allows players to use any wargaming miniatures in their collection. Over two dozen sample figures are detailed in this book, but the real strength of ARES is its figure creation system, that encourages players to use their imaginations — which is the way it should be! Also included is a fully-customizable magic system, providing players with the opportunity to design their own spells for their troops.
