The gameplay loop in this one is extremely fun and feels the most rewarding out of all the games in the series. However, it's hard to look past the extremely lacking RPG elements and poor writing, especially coming from games like Fallout 2 and New Vegas.
The Far Harbor DLC was a pleasant surprise and I heavily recommend it, but then Nuka World came and forced your hand into being an evil character with no other valid approach to conflict resolution other than basically not playing the DLC.
Still I will definitely revisit at some point.
