Animals that you can hunt and get skin and meat from would be good for medieval, being able to walk into medieval buildings with functioning door, quests, inventory, 3rd person view, player body, more NPC, better AI, I understand some of the things would get done maybe down the road just wanted to throw you my thoughts, and some probably no one cares about at the moment, just my thoughts, that's it for now if I think of more I will let you know
