I've really enjoyed what I played of ToTK (and think it's a big step up from BOTW), but it's still a pretty carefully limited scope even if it has a big map and the physics it does support are great and interesting. It's not trying to be a Bethesda game, and it's great at what it does.

I'm not saying Bethesda is perfect (and Fallout works less for me than Skyrim, even before whatever 76 was), just that there's a certain scale/complexity where it can no longer be comprehensive. I promise you they invest substantially in QA and testing, but unless they just call the first 6 months after launch an open beta for millions of players to find and report bugs, you can't catch everything, let alone in a way that it can be reproduced and diagnosed. There aren't enough testers out there to do it.

There are lots of options for more contained, more polished experiences, and it would be extremely disappointing if a company like Bethesda, who take on scopes no one else does, scaled back far enough to make a flawless experience. All the stuff that would have to be cut out to make testing manageable would take way more from the experience than the bugs do.
