This is why I don't get why the game industry has such a bad rep for overworking people. It's genuinely hard to do this kind of code so you'd think they take care not to scare away the few people who can do it. I recall at one point Goldmans was bragging to my team about how they'd hired a game dev to do their click-to-trade currency UI. Seemed like the guy found an easier job for more pay.
I think some may do it anyway by free will or by social pressure, but these people are probably pretty rare. In my country (Sweden) we don't really have a culture where companies pressure people into working more in general so those who do often meet a lot of social uproar and protests.
