I liked the game much better before they 'fixed' it by adding NPCs- before that the desolation was just creepy, and there was a lot of storytelling in the notes and tapes you'd find. But it is pretty much just wandering around an open world- there are grinds if you want them, but mostly I've just used them to guide our meandering. And the main quest line is ok, it's just not as extensive as doing 3 or 4 with all the dlc.
What is weird is that people who don't like it just can't accept that it's just not to their taste, and that maybe they're not as big Fallout fans as they think- every post about it has people who act like it's a crime against humanity, whether they've played it or not.
However I would say if you liked fallout 4 then current 76 is worth it on sale especially if you have a friend to join.
I played 76 for about two hours and gave up. It's just not the same. I guess that's not inherently bad, if people want different. But I wouldn't say that if you liked 4 that it is definitely worth playing 76.
Honestly I no longer resent the Bethesda games but for whatever reason despite replaying 1 & 2 multiple times (including in recent years) I just can’t get into the 3d ones. NV was the closest but it still didn’t manage to grab my attention for more than a weekend. 3, 4 & (via gamepass) 76 didn’t even get that far (a couple of hours each).
This kind of defeats the purpose of the whole game though.
