Legends of Old Mars is a Edgar Rice Burroughs’ Barsoom variant of Games Workshop’s Lord of the Rings / Legends of the Old West game. I think that system is perfect for playing games involving John Carter, Tars Tarkas and the other denizens of Burrough’s Barsoom.
Marcus Reynolds offers Warriors of the Wasteland, a set of skirmish level science fiction rules that he devised when he became tired of the shenanigans of a certain miniatures gaming company who shall remain nameless but whose initials are GW.
Here’s a neat set of science fiction logos from the past 40 years worth of television and movies in font form. That’s neat, becuase it allows you to scale them up or down as needed. Very useful for science fiction games.
I don’t like Pringles chips. As far as I am concerned, they taste like cardboard. But the cans are massively useful for miniature wargaming purposes. Here’s a link to s a site that tells you how to turn those tubes into storage containers for your miniature wargaming terrain.
Blasted Planets is Lance Runolfsson’s set of free science fiction skirmish rules to support his line of miniatures. Lance writes:
Blasted Planets Skirmish, is basically a set of house rules a few friends and I use to play games with my Sci-Fi figures. I am not trying to model a “Hard” Sci-Fi environment here. I’m borrowing as much from Horror and Fantasy as I am from Sci-Fi. I mean how serious can you be. When you have, Dog headed, Gator men chasing an Elephant guy around an Omni Field generating White rabbit? There is enough “real” world framework here that basic tactics work (most of the time). But enough of a fantastical element that you really can’t count on the idea that the Fin headed alien with the pin gun is going to nail the cave man with the rock every time.
