You either loved or hated them, but there's no denying that Fallout 4's base building mechanics formed a large part of the open world experience, which structured itself around defending your outpost from hostile attacks and developing relationships with other settlements. What you might find interesting then is that this aspect of the game nearly never made it into the final product at all.
Speaking with NoClip's Danny O'Dwyer as part of a historical documentary covering Bethesda Game Studios, studio director Ashley Cheng states that the feature was on the cutting block for a long time.
It's interesting that the mechanic may never have made into the final game, considering if rumours are to be believed, the upcoming Fallout 76 is set to be built heavily around the customisation of your own settlement as you scavenge for resources.
