I have posted an updated set of miniature skirmish rules reworked a bit to fit within terms from my forthcoming Sword & Shield RPG. These are available for free download now in the Sword and Shield image link to your right along with the sample S&S RPG stuff.
They are very simple and easy to play! A battle lasts maybe 45 minutes to an hour. Much less when you have the rules down pat. I have played using both 15mm and 25/28 mm minis with no issues at all. Give it a go and let me know what you think.
