Yeah it's very light on the RPG elements. The dialogue and interaction elements are really bad IMO. It probably helps that I don't game much these days. The only other game I've played in the last few years is The Long Dark so there's a bit of a pattern. The thing I've enjoyed about it the most is simply wandering about. The world is huge to explore and even with all that time I still haven't seen all locations. I don't mind the settlement building part either as long as you ignore the minuteman stuff.
