Fallout 76 is the most accurate depiction of a post apocalyptic world ever. It's messed up, empty, everything falls apart, and the bugs have taken over. There's even a bug that deletes the entire game from your hard drive. Yes, seriously.
And apparently much of the code is copy-pasted straight from other Bethesda games as there's at least one bug from Fallout 4 (which can't be patched apparently, since the Fallout 4 patch is community made and doesn't work for the new game). And because the game operates mostly client-side there are ways to cheat that can't even be detected server-side. That hardly matters though, as there are no good reasons for playing with other people. The game isn't hard, sharing the already bad loot is a bad idea, and you can't really even kill other players in pvp.
There's a rumour going on that the next Elder Scrolls is going to use the same game engine which would be a disaster.
