Fallout 4 in general featured a lot of dumbing down of the RPG elements from previous games in the series, and from other titles in the genre, including Bethesda’s own work, too. But one area where the game did great was with its crafting mechanics, especially in the new settlement system- the settlement system let players create entire new settlements from the ground up, and manage them, using all the junk and loot that they were picking up.
This was the one thing that Fallout 4 did so well that we actually want to see it return in future Bethesda games- including the upcoming The Elder Scrolls 6. A settlements mechanic in The Elder Scrolls 6 actually would make complete and total sense- especially since the previous entry, Skyrim, already had a smaller and more limited version of it added via the Hearthfire expansion.
Take that, and consider other things that you could do in Skyrim, including becoming the Jarl of cities and towns- combine the settlement creation mechanic with an expanded version of that, and you could have a full fledged city management simulation metagame present within The Elder Scrolls 6. As long as this wasn’t being added to the game at the expense of the core RPG elements, as was the case with Fallout 4, I hardly think anyone would complain- I know for sure that I wouldn’t.
