Basically, I like the fact that not everything in Unreal World is craftable by the player very much, for example, that there is no iron forging or the preparation of wool and plant fibers for clothing. It feels realistic in the way it is. On the other side I don't like the "magic" that too many items appear in shops which can't be crafted. For example, there is plenty much birch bark around in the form of trees and there is obviously an insanely large need of birch bark in the villages for boxes and containers and you can peel the bark from trees for hideworking, but there isn't any birch bark. In this special case the game feels quite incomplete.
Additionally the player's crafting skills rely much on woodworking and hideworking, but I feel like there should be a little bit more, at least concerning the basics. The player's character is capable of crafting leather shoes, but he/she cannot even make simple birch bark shoes out of some cord and some birch bark which feels quite unsatisfying especially when starting in winter without any shoes. I'd like to have self-made birch bark shoes so much. Please add them!

Maybe it could also be possible to create the most simple container out of birch bark, the birch bark boxes, to give another use to it. And I guess it would be nice to have a birch bark related quest since there is really much demand in the villages for it.
