Here in Sweden it is very common to play video games. While far from everyone is a "hard core gamer", most people at least seem to play some games on their spare time. Gaming is only a social stigma here if you don't have anything else going on in your life than video games. They actually played that at a local club not too long ago, and quite a few people imitated the more iconic movies (like scorpion's "get over here"->uppercut) on the dance floor.

I'll be considered childish, nerd, or both. Older people say you are being childish and blah blah luckily my parents are a bit tolerant. Younger people look at you weirdly when you imply that you don't get drunk every weekend. At least so it is with people near me. That's why I not mention gaming when I meet new people, so maybe the gaming stigma actually is on retreat.
