Lord Merlin’s Rules of Engagement is a set of free wargames rules for medieval style wargames. What makes these unique is that they are designed for large scale (70mm) figures. Despite the “Lord Merlin” monicker, there doesn’t seem to be a fantasy component here.
Black Powder is a set of free wargames rules by Wes Rogers for skirmish warfare in the period 1600 – 1870.
Danegeld and Dragonships is a set of free wargames rules for dark ages skirmishes. It has an interesting turn mechanism in that the side that gets the most kills has the initiative the next turn.
The older I get, the more I like simple rules sets. Here’s one for Samurai Skirmishes.
From the introduction:
Sensō is a skirmish game, 1:1 figure scale, for 25mm miniatures. One scale inch represents six feet and one turn roughly approximates one-two minutes. Bases should be square for foot, approximately one inch. Mounted can be 1” x 2”. The game is WYSIWYG (What you see is what you get); figures are armed and armoured as they appear.
Serious Lemon’s Full Command is a set of free wargames rules:
for simulating battles all the way from a skirmish level with a handful of individual models through to full scale war with units totalling hundreds of miniatures.
Full Command has been designed to be setting and scale agnostic. It can be used to play 28mm skirmishes in an ancient setting to 15mm ranked warfare in a medieval fantasy setting to a 32mm heroic squad based battles in a far sci-fi setting.
Full Command is being released under Creative Commons (Attribution-ShareAlike) to allow maximum flexibility and freedom to gamers everywhere. Always wanted to play that game where Zombie Alien Pirates are battling the Savage Ape-Men on Mars? Grab the core rules, whip up a setting module with a couple of factions and you’re away.
