I never understood why they took that step back, NPCs had personal schedules that changed depending on the time of day and week! Guards had shifts! NPCs actually took their armor off when they went to sleep, the dialog to the npcs added a lot of ambiance(Instead of the wind up dolls in Skyrim), and bunch of other small things that made it feel more alive.
Don't get me started on the cities, I love Skyrim, but the cities felt like movie sets, A blacksmith, general goods, potions place, maybe a fletcher in each city... where do the rest of the NPCs without houses live?!
Oh and not seeing the holstered weapons in Fallout 4, in 3rd person your character just slightly lowers their hands and the weapon vanishes, where did the minigun go? Probably up their magical [censored].
We all know that next game is going to be like Mario Party at this rate.
