The Miniature Wargaming Editor Lion’s Lair is a free print-and-play board game from Lou Coatney. He describes it as:
A fast-playing, point-to-point game of the British trying to battle their way through U-boats, Italian subs, Italian aircraft, German StuKas, Italian MAS motor torpedo boats, and the Italian fleet.
Manorhouse Workshop has a set of three tutorials on making wargames terrain from high density polystyrene (insulation board).
Corvus is a set of free wargames rules for fighting ancient sea battles.
Dinosaur Cowboys is a set of role playing / miniatures rules that reminds me of the old comic Cadillacs and Dinosaurs. It looks like a lot of fun.
The Sword In The 20th Century is a variant of Larry Brom’s classic The Sword and The Flame colonial rules.
