Anybody else recognise this sequence of events from Fallout 4?
You realise you can finally build stuff in the world. Wahay!
You gradually take control of several outposts and upgrade them to support the people who live there.
You build massive, complex, outposts until the framerate slows to a crawl at each location.
You get stuck in a loop of servicing all your outposts until it's pretty-much the only thing you're doing in-game.
You end up simplifying all of your outposts until they fulfill their requirements in the most efficient possible way and are, basically, a big shed with a heap of sleeping-bags on the floor.
You build yourself a "base" which is, basically, just a simple shed with a line of crates that contain all your stuff, a bed and space for all your workbenches.
Thing is, base-building can be fun but there's rarely much gameplay in it.
It's an arbitrary thing which you can choose to indulge in for your own gratification but, once you're bored of it, all that's really needed is storage and utility.
Maybe I'm being pessimistic but when/if FDev start focusing on giving us tools to allow us to build bases, it probably means they've run out of ideas for what else to do with the game.
