I know several people who used to work in the video game industry, and I used to as well (I still may get back into it eventually). It's much harder to convince interviewers that you can handle the work than it is for you to be able to do that work.

Granted, there was a lot I've picked up over the past few years working for large corporations, but not all of it was good. And there's just as much awful code in business applications as there are in game applications, and it's even less fun to debug them.
