I found the story to lack depth and intrigue, and it didn't have any avenues to roleplay. And the voiced generic main character is a chore to listen to.

On the other hand, the exploration, the environments, quick item loot system, and gunplay were all great and a step up from 3. And I had decent fun making a nice building to show off my power armour and other toys.

Far Harbor DLC: Really nice atmospheric environment to explore, story / missions didn't leave an impression, I don’t remember what happened at all.
