Sorry, read only first couple pages of this, didn't see it mentioned, but could have been...
My disappointment came at not realizing the settlement could go on after time limit was up, leaving me to have really given up a day or two before I saw it would continue, then picked back up. It is my first time through, have 14 of the 17 or whatev is needed, and still don't know if there is a point to finishing. But, I am going to continue and finish the quest I am working on (Build the Dojo) and see if it gets me anything... If I knew it continued, I would have kept harvesting goods and planning. Also, it took me some reading to learn the way to finish by building then un-building, erasing roads to make room to move things around, or add "handshakes."
So, I'm happy that at least I won several items through quests, and if i get something for finishing, even if not on time, I won't consider the time, money, or supplies spent a total waste of time. Also, glad to read impediments change, at least it is not just an automatic response every time through. But, I like a puzzle. That's more fulfilling to me than plowing through. Some play differently, I'm getting that...
