In my professional life, I kept my hobby gaming in the closet. In the division that I work for now, it's far more open, but I have in the past worked for companies where if it was found out that I was a gamer, I would be immediately fired because only IT/programmer folks do that "kompuuter" stuff, grow beards, look scruffy, wear jeans, etc. The finance guys must be immaculately professional 24/7, no exceptions. We manage the finances of multi-million projects and clinical trials, no fun and games allowed here.
