Although I started with Traveller at age 16, I got my copy of the AD&D 1st Edition PHB that same year for Christmas, and finally found a group to game with the year after that. It was the fall of 1986, and because I read voraciously, I soon knew more about the game than our GM... big mistake when you are still in High School, but it didn't sour me to roleplaying at all.
Now, it's been 21-ish years, and I'm still into gaming.
And all thanks to my Dad, who wanted to play but was always concerned about the age difference and people's impressions. Roleplaying was probably the second greatest gift he ever gave me.
Rest In Peace, Dad,
Flynn
