Battlelore is a great card driven fantasy/medieval miniatures/board game. Here are a set of rules for making it more historical than fantasy.
Beware, though. The site has a noxious pop-up video ad on it.
Free Blood Bowl Pitch
The Gaming Corner has twenty different Blood Bowl pitch designs free for the downloading. Just print them out and glue the pieces to cardboard. The site also has Blood Bowl rosters and a quick reference sheet.
Tourney Jousting Rules
Tourney is a set of Jousting rules from the Lincoln Miniature Wargame Society.
Quick Napoleonics
Back when MWAN was still being published, it was my favorite wargaming magazine — in no small part because of the variety of interesting characters who wrote for the magazine. One of those was Friar Aelred Glidden, who is perhaps the world’s only wargaming monk. Glidden’s game rules were always simple, but interesting, and I very much miss reading his works.
Quick Napoleonics is a set of free wargames rules inspired by Friar Glidden.
Wargaming In The World Of The Difference Engine
James Clay has written a fine article on wargaming in the world of the Difference Engine.
For those who don’t know, The Difference Engine
is a novel by William Gibson and Bruce Sterling that takes the reader to a Victorian world in which Charles Babbage’s Difference Engine drives cybernetic steam engines. While I did not enjoy it as much as Gibson’s Neuromancer, it still was a good read.
