But if it's your only hobby, maybe branch out a bit? Especially if you're single. Great way to meet people and form bonds over like interests.
I don't know anyone who's only hobby is gaming who isn't single. Admittedly, my sample population is kinda skewed, but of that group I don't know anyone with a few varried hobbies who is single either.
Unless you're happy being single. No joke that's perfectly valid too.
Bunch of my high school friends I still game with several times a week, plus a few friends we've met along the way. We find it funny how in school jocks would pick on us for having Counter-Strike LAN weekends, but now we hear those kind of people all the time in FPS voice chats.
