From publisher blurb:
Cavemaster is a serious Stonepunk tabletop fantasy role-playing game of Pleistocene adventure using the Habilis game system. The creature list is extensive and authentic, with a few cool anachronisms. Cavemaster isn’t just a tabletop RPG where you play a cave-man. It's an RPG that cave-men could have played!
WHAT IS HABILIS?
The Habilis game system is a fictitious archaeological re-construction of the role-playing game rules first used by our Homo Habilis ancestors approximately 2 million years ago. Habilis requires no components that can’t be found in nature: rocks, sticks, and bits of animal hide rather than paper, dice, hex grids, or plastic or metal miniatures (though you certainly MAY use more modern components, if you wish). It requires no written language or detailed record-keeping either, and its mechanics are simple enough to have been passed down verbally from each tribe’s Cavemaster (CM) to his (or her) apprentice(s).
Abilities are represented by groups of small stones on your ‘character skin’. In a challenge, you pick up the relevant stones and secretly divide them between your hands. Your opponent (or the CM) does the same. Each participant picks one of the other person’s hands, and the stones in that hand are revealed.. If you reveal more stones, you succeed!
WHAT IS STONEPUNK?
In the tradition of Cyberpunk and Steampunk, Stonepunk is an exercise in speculative fiction. Stonepunk turns the clock back to the end of the Pleistocene Epoch (approximately 10,000 years BCE), and asks what might have happened if the culture and technology of that age had developed further, or in exciting new directions!
