Would it be possible to have _two_ barbarian civs? One would be regular barbs and the other the Doviello.
If not, I think of them as the Vikings -- the women and children stay up North. The men go on raids.
The city, I think, would be mostly meat eaters. It would be a collection of hunters. They would stay together to accopmlish food sharing (like the
inuit). Basically, food sharing allows a group of hunters to even out the feast/famine cycle of hunting. A successful hunter shares with everyone and, in turn, receives food from others when they are successful. Although everyone gets food, there's a hierarchy, based on previous productivity.
Where's the thread on Doviello and Tundra? What if their farms are -1 food but they get extra food and hammers from animals? Or the hunters generate hammers and food when sitting on an animal resource? Of course, the Vikings did farm (Iceland, Greenland). But I suspect they farmed later than other civs. Can you mess with the tech tree and make, say, Machinery or Iron Work a prereq for Agriculture for them . . . and still give them early access to Animal Husbandry?
Should they be scorched earth like the orcs? I imagine them as having a sheltered production center that generates raiders (this fits nicely with that speech: "these are our islands. . .")
What if the Doviello get an extra tech (fishing) to start to compensate for later slow growth? And do the same for the Lanun?
I think the smokehouse should be far more important for the Doviello. Take Granary away from them and give them a special smokehouse of some kind.
