Sim settlements has always had the rebuilding and taking back the wasteland vibe. But paired with all of the above makes it seem like you're taking back swaths of land with every settlement making everywhere safer from sanctuary onwards. I never truly got this feeling until after the pastor moved into concord. All it took was one in-univerese passing statement of how the area feels noticably safer then the rest got me fully immersed in the game. Then I started noticing the multiple mm patrols pattrolling the road with uniform blue and assault rifles and the realization was probably the most fulfilling thing ive experienced in fo4.
