I'd have certainly been in for life no matter how it played out, but shortly after I got into D&D (when I was about 10 years old) I got my parents involved, and later my younger brother as well. My father played for about six or seven years, my brother for slightly longer... my mom, at 52, still plays D&D with old friends of mine back home! In fact, she came to town to visit this weekend, and we played D&D... my fiance, my stepdaughter, my best friend, and my mom. I've always been pleased that this experience, as unique and intimate as it is, is something I've been able to share with my family.
