Dando Masdo - Level 1 Gnome Thief. This was 1990 (ish). I was in fourth year (of six) in high school, so about 15. We got a new Technical Drawing teacher (Mr. Main), a lovely man who really took a lot of time to help his pupils, and actually managed to make a dull subject interesting. We got talking one day and I mentioned the sort of books I read (LotR, Pern, etc.), and he told me about DnD. He offered to run a game at lunch time one day a week and we jumped at it.
About 6 of us played. He was very good at explaining things, and had a lot of patience. Then he died. He had a heart attack. Young as heck, probably late 30s or early 40s. I sent a letter to his wife telling her how wonderful he had been to us, or at least I think I did - although it is so long ago now that I cannot quite remember if I ever asked a teacher at school to give it to her.
Anyway, I was saddened, but also my interest had been piqued, so I went to the other teachers and asked if I could set up a lunchtime club. They said no, unless I could find a teacher who would supervise. I searched and searched and finally found a really young Physics teacher who sacrificed a large chunk of his lunchtimes for 3 years to let us run a club. It was a lot of fun. We played DnD (2nd Edition was out, I think .... but the memory is foggy), Carmaggedon, BloodBowl, Warhammer 40k, and learned how to use nunchucks (for real - sort of strange, but such is life).
I ran that club for almost 3 years, 2-3 days a week. It was incredibly popular. Probably averaged 10 people a day, possibly a touch more. I always DM-ed, because nobody else wanted to (and they seemed to enjoy my style), and because I loved the creative aspect of it.
Then I went to college, discovered girls and music, and sort of stopped playing.
