For me, Bethesda RPGs have always been more about the immersion into the world and the joy of exploration and discovery. Fallout 4 tries to be somewhat more narrative and character focused this time around, but it doesn't really work out. On the other hand, that really doesn't hurt at all the parts of their games that I've loved since I first played Morrowind nearly 15 years ago. In fact, despite the story and limited player character dialog options, the immersion and exploration are actually a lot better this time around, thanks to an insane amount of locations to explore, the increased emphasis on collecting junk for weapon/armor modding, and the best urban environments in any Bethesda RPG so far.
So, it really just comes down to what you want out of the game. For me, I'm perfectly fine largely ignoring the story and just going off on my own to see what I can find.
