Yup, it's shit. How can they keep thinking rationally while working 14-hour days? I just don't believe they can be fully productive all that time since game development needs a lot of thought process.
I've done product development in a customer facing role. Let me tell you, after a certain point, you're just rolling through it. I was regularly pulling like 12-16 hour days. Wake up get in at 6, leave at 10 trying to manage all that was needed to be done.
It's impossible to get back into the head space once you leave it, but it's definitley possible to get into it and get through it.
That said, it's an inevitability because literally so much of your day is just meeting with people to get through the problems they're running into, then you have to figure out the solutions then spend all the next day fixing it between meetings about more problems.
It's impossible to avoid crunch or it's equivalent in most areas of life whether education, software, law, etc. eventually, you just don't have enough time. You mostly want to minimize the periods of how long it lasts and you want it to be organized. You want deadlines.
That's probably where the attitude adjustments need to come into play. I watched the Grounded documentary the other day and it's just at the end where they talk about Crunch as this beautiful things you're just like "alright man." I get it because of what comes out, but there's so many ways to avoid it for as long as they experience it in games.
