i remember around 7 years ago our warehouse boss, who was in is 40s was playing halflife on his pc in is dinner break. and every one thought he was a weirdo except me. as i had the game at home, i still play pc games now in my 50s but some people frown on gaming. thats why i dont mention it to anyone.
I expect things have changed quite a bit now, what with the popularity of casual gaming with the masses. Greater source of revenue than music or film, iirc.
