That's a great question. It was work experiences that transformed a challenge into a stressful slog. There are some things in my work history that elicit a PTSD-like response. For example, right now I'm thinking of a software product that I used to have to administer on about 60 servers, and I can feel myself tightening up and almost feeling nauseous. This isn't related to my original comment but answers your question I think. My work experience definitely informed my preference toward games. I like problem solving and expressing creativity. But doing so under pressure is the opposite of fun for me, which is why that game was no-go for this greying geek.
