But how long did they keep this up for? Months-long crunch times popping up for, what, 5 years? Or did they keep this up for 10, 20 years? Burnout and health effects can take years to show up.
I suspect those that do this and keep up the pace move on to more organizational work later on, which isn't the same thing.
Lots of people leave the game industry like me, but there were definitely those who did it for 10 years straight.
