I think gaming is a factor of personality. Some of us will never outgrow them, but some of us have never understood the attraction. My husband finds nothing of interest in games, whether board games, card games, computer games. I, however, and our children, love games. I'm 59, and planning a big Guild Wars 2 weekend with my youngest girl, who's 31.
I really do think there's a common feature in our personalities that has nothing to do with age or gender.
Oh, Google thinks I'm a 35-40 year old man who is really into gaming, based on the websites I visit. Sillies.
