This sounds very naive. I've gone for beer with various people in the gaming industry. From ubisoft QA team leader to indie game programmer to Blizzard Project Manager. All of them were tired of their jobs. For all of them it was "just a job" and sometimes even less. It's these people that I end up going to beer with in normal social contexts. Maybe because the ones who really like their job don't go out. OTOH I know the colleagues in my company who spend too much time on their job and I really wouldn't want to go out with them.
I am interested in the indie game programmers being unhappy. That seems almost paradoxical, unless they were just unsuccessful. I cannot imagine Notch having a stronger passion that making video games.
