Hiya, I've only played the demo so not sure if some of these are already in game:
allow animals to be kept in fences to breed and produce livestock and additional food (milk, truffles) guarded by a dog so the wolves don't eat them.
Clothing has stats to effect temperature, overheat in furs and too cold in nothing?
limit the inventory and introduce rucksacks, makes it more realistic. Maybe have horse saddles or carts (for humans and horses) to carry more...
