Not really, but I don't go around advertising it or anything just because I find that most of the people I meet who are openly "gamers" aren't really the kind of people I want to hang out / talk about games with. I know that sounds shitty, but that's just how it is. The risk of getting in some annoying conversation is just too high, so if I see someone with an Assassin's Creed hoodie or something, I usually don't want that guy knowing that I also like playing a lot of videogames. Usually I find real life video game conversations with people I don't know very well to be extremely shallow.
"Ay bro you play Dark Souls?"
"Yeah.... it's great. Played it for hundreds of hours."
"Ah that's cool man."
But I certainly would never deny being a big gamer, and I openly play games and look at NeoGAF around my friends, girlfriend, family, etc.
