Yes, thats what I mean. Total extermination of villages. Wiping out whole tribes was not as common far as I've been told due to the aforementioned dispertion. Though apparently not for wont of trying. Why? I have no clue. I assume over competition for hunting grounds mostly. At other times it seems like a tribe would go out of their way to exterminate a village/tribe.
Make of it what you will. Stuff like this can be interesting when applied to campaigns and finding out WHY this tribe is doing this, or trying to stop them, can become a major quest.
