Hello,
My ideas:
-Domesticate animals to have pets
-Make flock of sheep (with a cattle dog), or herd.
-The domesticate cows can be used to plow and to carry (big) stuff with a cart.
Will there be an economic system with money and other stuff ?
So we can practice a job like bread baker, butcher, farmer, cheese maker, blacksmith, mercenary, tamer, fisher, cook, carpenter and most of all an authority like guards or "policemen" to protect people form stealing and crime.(they can be the game master). And some mayor who tells to the carpenter where to build building to make a beautiful town. (and he can command policemen)
So we can buy stuff to other trader, it will be more easy to live in H&H.
