The first 5-10 hours can feel a little boring but once you get to The City of Defiance Bay things get pretty interesting. I have invested some 47 hours into it and haven't beaten it yet but I can say that there is a lot of fun to be had. Gotta get back to it and finish it someday. But yeah, it definitely ain't a disappointment. Fallout 4 was a disappointment, I mean when I reached Diamond City, the dialogue between the piper and the mayor was so stupid and childish that I simply said "oh! to hell with this, there are better open-world/RPG games out there...".
