Grav Armor is the classic Dwarfstar game of future armored warfare. From the site:
GRAV ARMOR is a fast-moving game of future armored warfare for 2 players. It realistically simulates the high-speed, high casualty combat between streaking gravitic vehicles, surface-effects craft, supersonic fighters, orbital dropships and power-suited infantry. The modular map sections allow scenarios to be played on radically different types of planets (earthlike, molten, frozen or airless).
James Catalano offers Bosconian D, a free solo boardgame based on the classic Namco video game. To find it, you have to scroll down to the bottom of the page, past his (very cool) retro video games downloads.
The Battle of Ayrene’s Woods is a free print-and-play fantasy board game.
Centre Rock is a free download and build board game from Rocket Ship games. It can be played with the included counters, but more interesting to me are the photos of the game being played with miniatures.
Miskatonic Madness is a free downloadable board game from Richard Launius, the creator of the original legendary Arkham Horror board game. This is a two player game and is very well done.
Here’s what Richard Launius says about the game:
this is an update of a very simple game I designed years ago and gave out a conventions to people who play-tested Arkham Horror and my more robust game designs. It is meant to be simple and in no way is comparable to Arkham Horror or Trail of the Brotherhood, but in it’s own right is fun and there is a strategy to playing the game. Lastly like Lovecraft stories, the magic of this game is in the imaginations of the viewers. With imagination it is a fun little game
