Far as I understand the setttlement map legend from the Map in the Pip-boy, the smiley and percentage signifiy how happy the people there are with you and your work, and the stick figure and number are obviously how many people live there at the moment. I also get that settlements are constant maintenance and quest-doing, but does the happiness percentage eventually decrease depending on your lack of urgency toward these people? And once you get a hundred percent, as that it for that settlement?
I've also placed defences on every settlement, but they keep getting pillaged and invaded. Do these measures help at all? Is there a scale to decreasing their constant need for Minutemen assistance?
Anybody care to explain how it works?
