I starting working in games in the early 2000s. The first game I worked on (Black & White) had me working 16-20 hour days, 6-7 days a week for 9 months. It destroyed my health and turned me into an agoraphobic for at least a year, with related conditions lasting much longer. I've seen people have to check into mental health institutions after shipping games.
At one place I worked, there was a "crack board", where they would have sweepstakes on who was going to come apart at the seams and lose it. Who knew mental health issues could be so fun? "lol".
Needless to say I no longer work in games, it has done damage to my body and psyche for very little return..
