Castle Cracker is a set of free wargames rules for backyard games in the ancient and medieval eras.
Miniatures Rules
Legends of Old Mars LotR LotOW Variant
Legends of Old Mars is a Edgar Rice Burroughs’ Barsoom variant of Games Workshop’s Lord of the Rings / Legends of the Old West game. I think that system is perfect for playing games involving John Carter, Tars Tarkas and the other denizens of Burrough’s Barsoom.
Warhammer 40K Darkest Africa Variant
Even if you don’t like the science fiction game, Warhammer turns out to be a pretty flexible system for playing other periods. Plus, it has the advantage of familiar mechanics and a built-in player base. So given that, its not surprising that it’s been extended to practically every period you can think of. Here’s a variant of Warhmamer 40K for colonial games in darkest Africa.
Savage Worlds Lord Of The Rings Skirmish
The Savage Worlds role playing system has attracted the attention of a lot of miniature wargamers becuase it is so easily usable as a miniatures game. There’s even a free subset of the role playing rules called Savage Worlds Showdown, designed specifically for miniatures skirmish.
Here’s a free expansion for Savage Worlds for playing Lord of the Rings Skirmish Games.
Fireteam II Modern Skirmish Rules
John Armatys offers a set of free modern skirmish wargames rules called Fireteam II They’re designed for use with 20mm figures.
