Wurm RPG: Core Rulebook - Ice Age

Adventure into the prehistoric past of our own world. In this long-forgotten time, many powerful creatures roamed 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). During your adventures, whether simply surviving or going on perilous hunts or legendary quests, your characters will gain strength, wisdom and prestige by exploring unknown territories, daring to enter the darkness of mysterious caves, seeking out the powers of ancient spirits, or challenging the creatures of the night.
