Like many gamers, I started off on one of the classics. Dungeons & Dragons.
Keith Dacson came back from RPI one summer with the original little books.
Advanced Dungeons & Dragons came out soon after, an we all stocked up on the books.
In those days, it was Keith, myself, Scott Carlson, John O'Kane, Ned, Grant Carlquist, Dave Arnoff and a few others.
