Age of Fantasy: Regiments is a set of free wargames rules for simple fantasy Regimental actions. The rules fit on one page, and there are “army books” for various races.
Miniatures Rules
Corvet Starship Combat Game
Corvet is billed as a “chaotic, fast-paced skirmish game of starship combat for two or more players.” It’s a bit more granular that most, in that you control individual crew members in your vessels
Battle of la Drang Rules
Battle of la Drang is a set of free wargames rules for battles between the US 7th Cavalry and Vietcong forces. The battle of the title was the basis for the book and movie, “We Were Soldiers.”
Dying Star Oblivion Skirmish Quickstart Rules
Dying Star Oblivion is an skirmish game based on Samsun Lobe’s Dying Star series
The Green and The Tan
The Green and The Tan is a set of fast play rules for combat with plastic army men. I have to say that at first I thought it was about an Irish rebellion.
