Unfortunately, I did not notice whether task chains were planned. It would useful for trading in co-op or solo. what I mean by this is a simple chain such as:
Point A: picking up raw materials
Point B: transporting and storing or picking up raw materials …
Point A: return and new start the chain.
A trading post / trader who can exchange raw materials. In the beginning maybe something like skins against copper of the same value. Later in the game there might even be something that can only be produced in certain areas. that would give an incentive to work together I think.
