I know people who used to work in game QA work, the key term is used to, the work isn't there anymore. Yes those jobs literally still exist, but it's not like it used to be, they're almost always contractors and where they used to hire in droves, the cycles are shorter and more last minute, with less people.

The dirty truth is that day one patches are a result of trading a release date for money - they budget for releasing, getting money from the sales, and using that to pay the last part of development. They're borrowing against the future, and they collect so much data from games that they get to effectively test games they know are not finished on consumers.

It's so much worse than you can imagine.
