As it is not paid (yet), there is no real asset list. I'm happy if I get any help at all.
That said, I have a lot of ideas that I need assets for. Complete structures (houses and such things) with all the details would be nice to have so I can add a couple quests. For example a guard tower where I can put a guard on top and then a quest to bring him his meal and as a follow-up quest he tells you about a missing guard and tells you to find him and you find his skeleton eaten by a bear which in turn gives you another quest to kill bears and find out why they have become aggressive. That is possible with some assets, I'm just missing the skeleton and the bears and some UI icons, the guard tower I can build myself theoretically.
