The first core book I remember owning would have been AD&D 2nd edition. I may have owned the D&D Rules Compendium, but I didn’t understand it. The 2nd edition book led to my first true gaming group during high school. I played Friday nights at a friend’s house. I could not tell you who or what I played, only that I did play and had no idea what I was doing. I was out of my league playing with seasoned veterans. They helped me learn and eventually I would leave them for a game of Vampire: the Masquerade with a group my own age.
