I started playing D&D during the Thanksgiving Holidays of 1976 or '77. I had gotten a pamphlet, single book, version for my birthday. Christmas of that year, I got the red box set complete with "Caves of Chaos". A couple of years later I was introduced to AD&D by some friends at school.
I have played basic D&D, AD&D 1e, 2e, 3.0-3.5e, Traveler, Gamma World, GURPS, Shadowrun, and Vampyres. I have now played 5.0 and Pathfinder as well.
As I have gotten older, I have found much more entertainment in the role-play and less so in the hack-n-slash.
