Hey Love Gun,
I think those are all nice ideas to make a more varied crowd and further enhance the atmosphere. But honestly its just eye candy at the end of the day. I can only deliver what is really neccessary and then move on to the next topic. So the small variety of people have to suffice for now :)
Regarding the merchant with the donkey, he was part of the “specialized trader” building. It didnt end up in the game because we decided to not focus that much on trading. Maybe we will implement it in a future iteration of the game.
