Andrew Fisher has created a set of free Napoleonic wargames rules called Throne of Bayonets. Andrew writes:
I like a set of rules to tell me what it is trying to do in the introduction. This lets me get a quick idea of whether I’m likely to enjoy the game, and therefore helps me to decide whether or not to buy. Most rules allow only 5 minutes action in a 15 minute turn in order to ensure that battles last more than 20 minutes; this set uses a realistic time and ground scale to allow very quick action — sometimes — but it also ensures that a lot of time is spent in waiting for orders or in indecisive firefights and half-hearted cavalry charges. To make this workable you have to be able to play a lot of turns, so I’ve made the rules very simple, with a minimum of tables and dice roll modifications. In playtest, players using up to a division each proved able to fight in close to real time, even in their first game.
Incidentally, the title comes from a Boris Yeltsin quote from 1991: You can make a throne out of bayonets, but you cannot sit on it for long.
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.
