They can be seen as a hindrance by the devs if there was no clear definition of what is a bug. If the guidelines are clearly defined, that is not case. Even if the definition of a bug is never the same as the beginning and at the end of a project.
You're saying as if that is something strange. All games ship with crap load of bugs.
And with online some bugs are corrected post launch or many times between gold release and release date(day 1 patch).
Perhaps by morons and arrogant people that think they know better.
If your testers turn a blind eye to a showstopper at any point in development, they are garbage QA and should be sacked immediately. Write it up and if the producer wants to waive it in the database it's on their ass.
QA find bugs but when its comes to what get fixed and when it's beyond them. Throw bug quotas in there and it becomes a toxic mess.
I have a friend who worked at EA Tiburon back around the early ps360 era and he said they had weekly quotas. I thought I'd love to be a game QA tester until he told me about how it was working there.Everyone loves the QA guy who finds a few bugs. Everyone hates the QA guy that finds a lot of bugs.
Fallout 76 and Bethesda's extensive mod community says you still can't.Bethesda proves you can. How they get so many sales of their in house games have with how much of a technical mess they always are I will never know.
