At my wedding 4 out of 5 of my groomsmen were friends I made through gaming, but those friendships blossomed beyond just playing games and we all became lifelong friends.
Anyways, just gotta put yourself out there man. Don't live in a city or big town? Travel around to game stores, conventions and tournaments for games you are interested in. You will find plenty of friend potential there.
I think the biggest hurdle now, as opposed to "back then", is I was part of the last 'arcade generation' of gamers. There was a lot more socialization in-person back then. People were forced to go out and meet people if they wanted to play a game vs others, even if it was at someone's house.
Nowadays online connection quality is good enough to dissuade gamers from leaving their couch (coupled with a lot of cities losing most if not ALL of their arcades and LAN centers), as they can get their 'social gaming' in from behind a TV screen or keyboard. I doubt if I were a teen in this era, that I would have met even 1/2 the people I know through gaming, maybe more. It's a shame but that is the truth of it now... but that doesn't mean you can put yourself out there and find events/LANs/conventions to hit up, it just makes the work of finding people harder.
So yea... I think there is a message somewhere in there
