Yeah, it's never worth it.
I remember working 70-80 hours a week, 7 days, when I worked at Konami. Activision too. They work you to the bone and then some. Then they have the nerve to get pissy if you call in sick or can't make a shift because you're exhausted. I never saw my wife, because I worked the night shift, and by the time I got home at 11am, I went to sleep, then woke up around 3pm to hop on the bus to head back into work and work from 7pm-7am. It was a nightmare, and it's not like we were working on games that ended up being worth a damn. It would maybe have been a little more tolerable if we were working on something that ended up being a classic. But it's fucking Activision, or Konami (and not a Metal Gear title).
The best place I've worked in the industry besides Capcom was Obsidian. Those guys and gals were awesome, and it was a very positive, familial environment. Feargus Urquhart was a really cool, affable guy that I enjoyed talking with. The other companies I've worked for weren't nearly as pleasant.
We work our asses off to create what we hope is going to be a fun, entertaining game that's worth your time and money, but we're also sacrificing our health and relationships to do so. It really isn't worth it. I love working in this industry, but it takes a whole lot out of you. I've been in it about 11 years now, and thankfully, my current role doesn't require back-breaking hours, so it's been wonderful.
