Now, speaking of friends...
Sometimes I feel like I wouldn't have any friends if it wasn't for gaming.
Of course that's not true but I will say that I definitely met the majority of my current collection of good buddies, my girlfriend, and most of my close associates thanks to our mutual love of RPGs.
I only know my good friend Carl because we met online in a Google Hangouts group only to later discover we lived within relatively easy face-to-face distance. Now I am friends with a fairly extensive group of people thanks to that Google group but I actually get to see Carl in person.
One of my best buddies is Dave, one of several Daves I've mentioned on this blog in the past, but this particular Dave is a fellow I met when he dropped into the second or third session of a game I was running at my FLGS. That was over five years ago, probably more like eight, and we talk about a lot more than gaming.
My point is, when people share a common interest, there is no guarantee that they'll end up friends. Friends are a deeper thing than just a gaming buddy. Friend require more of a commitment on the part of two individuals to make the relationship and connection work and become something you want to come back to again and again.
Still...friendships forged through gaming seem to be pretty solid and last a long time. I vaguely remember someone describing it as similar to the connection people form when serving together during military actions. Well, I don't know if I'd go that far but I get the gist and I can't argue with it.
In summary, I have a lot of friendships I've made because of RPGs. The best ones have continued and become stronger not because of RPGs but because of friendship.
