I kid, but I enjoyed the settlement system in FO4. The idea of forning the foundations of a new country in the same place where the foundations were laid for the US was kinda cool.
Depending on which ending is canon and whether the Minutemen stay the course (and appropriate BOS and Institute tech), they could become like the NCR. So a little imagination can restore the tedious defects of FO4. Give that Tato farming a purpose. Today Tatos, tomorrow the World.
But I still think FO4 suffered from a sub-optimal allocation of development resources. The work that went into settlement building and radiant quests could have gone into creating new and interesting locations to discover and quests. Possibly unique land formations that developed after the nukes hit.
A voiced protagonist also fouled things up. Work that went into writing dialogue for the player's character could have been devoted to writing for NPC's and their reactions to more varied textual responses from the character himself.
I liked Fallout 4 a great deal. Don't get me wrong. It's still one of my top favorite games, but like other Bethesda outings, I think it leaned more toward a really dressed up junk collection/settlement building sim than an immersive RPG experience.
