Your initial definition would have not included me. That said, I do consider myself a gaming entusiast: videogames are currently my main hobby (and they have been so for most of the past three decades), I spent several hours a week playing videogames, I generally tend to play the best I can, I met many dear friends thanks to gaming, I am something of a laid-back achievement hunter (gamerscore of 241.000+), I stalk and/or participate in gaming forums, etcetera.
