from the publisher's description: Würm is a system-lite RPG with an indie aesthetic that sets in the last period of the Ice Age. In this long-forgotten time, many powerful creatures roamed over a vast territory covered in steppes and taiga, reaching from the white mountains to the raging sea: mammoths, aurochs, bison, giant deer, cave bears and cave lions. Among these huge creatures, two species of humans live in small communities of hunter-gatherers: the robust Bear Men (Neanderthals) and the taller Long Men (Cro-Magnon, or Cavemen).
