O.K. So it’s not miniatures, but anyone my age will remember the classic SPI game “Dawn of the Dead.” There’s a downloadable version here.
G63 Gettysburg 1863 is a hex-and-counter board game of the battle of Gettysburg. The print-and-play game is free for the downloading. I am not sure, however, if it is entirely serious in nature. There are just two counters and the board has just seven hexes. The rules, however, seem to indicate something more serious. Strange.
Acies is a very nice looking two player card game designed to simulate conflict between ancient armies. it looks like it would be a fun thing to play on off-nights when your regular miniatures games end early. All the parts you need are there to download and print out.
City of Guilds is a print and play board game about gaining influence in a medieval city. Players do this by assuming the role of one of the great guilds and playing action cards.
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.
