Okay, my thoughts on Fallout 76:
I Sincerely hope Bethesda learns from the issues Dark Souls 3's Co-op has. Amongst other things I've heard so far from our sweet little liar, you retain your skills when jumping into another person's game. So if you have something like a high-level Toughness or Mysterious Stranger Chance or Bloody Mess, and join a lower-level's party, you could really fuck some shit up. So what's stopping low-level gank squads?
Also, the concept of a nuke that anyone can use on any settlement sounds fundamentally broken. If aforementioned gank squads stockpile enough of those, some serious shit could get fucked.
Everything else seems okay about it though. Not many changes from 4, it seems.
