I clicked 10.... it'll be 10 years this October.
They'd just opened a hobby store in my town. It was often opened at night for Warhammer games and that kind of stuff. A friend invited me to go there a night and see him play Warhammer 40.000... but he didn't show up. who I found there was the shop owner (now one dear friend of mine) DMing a game.
I sat there. Thrilled. Watching them.
I talked the whole time, asking, suggesting. (The group are now all friends of mine, though we never played together, but that night I later learned they'd asked the DM "Get him out of the room. Or we will, and it won't be pretty.)
I went home and I COULD NOT SLEEP. I had to try. It was... it was EVERYTHING a game could be.
The DM started a new game for me and a couple more guys , in LOTR, a few days later.
Sorry for getting carried away, but it's... it's a fond memory. RPG brought me to meet almost all of my best friends, my wife (a friend of fellow players), and is a very important part of my life.
