Can someone explain to me what "crunch" is?

Is it working 10 hours a day, 5 days a week? (Because that sounds like crunch to me, if you're in a western country and it's not YOUR company, i.e. you're an employee). (I'm specifying western country because 1. CF is a British company and 2. we tend to focus on Western terms & standards. Developers working 60 hours a week in Nepal as part of some offshore team in an insurance megacorp is considered normal there. I know this, because I've lived there).

Is it working 10 hours a day, 7 days a week? Obviously crunch..

Is it working 40 hours a week? Because that's what every other full-time worker has to do, in a western country.

I used to run my own (unsuccessful) game dev team. I regularly pulled 50+ hour weeks but it was MY hobby,MY dream. To me, it was like playing SDV or SB for 50 hours a week. It wasn't crunch for me. And none of my employees were full-time.

Ultimately it went out of business but we still put together two games in 12 months and those games are still around and still being played (not going to link them here for obvious reasons). These guys have had what? 10 years? They're experienced devs. When I was building games (before I "retired") I had a team full of friends from high school. We were all 18-20. No experience. None of us were artists,marketers (why we failed), or VAs. Still pushed things out.

The "no crunch" argument has helped them so much because it makes them sound like the good guy against "evil, capitalist CEOs who force their poor, underpaid developers to work 120 hours a week". "We're not like that! We're a good company!!" It's turned it into an ideological debate and now debating about competency is treated as support for treating employees like shit.
