Epoch - My Next Campaign Setting?

I found a game called "Epoch" not too long. I talked about it briefly with Ra'ziir's player this weekend (in between attempting to fix the stove - found the part I needed yesterday so it's up and running again and dealing with the water leaking from the bathroom into the kitchen).

In short, 20,000 years ago during the Pleistocene epoch (last ice age), somewhere on what would eventually come to be known as the Scandinavian Ice Sheet, we find a band of hunters....

Vast regions of the world are covered in ice. Humans are slowly clawing their way to dominance over the declining Neanderthals and nearly extinct Cro Magnons. Every day is a struggle for survival. Rival tribes competing for territory, dangerous predators, freezing cold, and vengeful spirits all threaten your very existence.

You are either one of the Bone Children (Neanderthal) or Stone People (Homo sapiens), a member of a hunting party - hominids eking out an existence in a hostile world. Your party is nomadic, following the herds across the tundra, hunting antelope, bison, and, if an alliance can be reached with another party, wooly mammoths or wooly rhinos all while avoiding giant bears, long-toothed cats, wolves, and other perils.

Rumors persist of warm, sheltered valleys without snow or ice where abundant game can be found but you have never seen such a place yourself.

Thag is short and scrawny but his mind and fingers are nimble. He is good at skinning and sewing furs and flintknapping.

Note: Thag's name come from Thag Simmons of "The Far Side" fame and his clothing is loosely based on Fred Flintstone's orange and black attire.

Game mechanics are pretty simple. The DM sets a difficulty and the player rolls 2d6 (3d6 if the task is related to their specialized field). If the roll is better than the target number, the character succeeds. Items (bone and stone weapons particularly) are prone to breakage due to substandard materials and the limitations of manufacturing. There are rules for shamans (characters who specialize in Animism), so enlisting spirits to help is possible but only a handful of spells exist.

Xp is earned through hunting, avoiding or overcoming dangers, and good role-play. Levels are gained every 25 Xp so everything is pretty simple.
