For starters, the fans would love it if Fallout 4 takes realism to a whole new level. The red indicator to tell the foes from friends should be removed in the fourth sequel. This will force players to approach with caution as they are at full risk of being attacked from any individual in the barren Wasteland.
A scenario is painted in the discussion where the player comes across roamers in the Wasteland. They can just pull out their rifle and take out this group of people. However, there is a chance that they could just be unarmed deserters.
For a post-apocalyptic game, having this feat will surely take the survival experience to a whole new level. Perhaps, Bethesda could introduce this by giving each and every NPC names. From there, nobody can tell if the person is a hostile or a friendly.
