I got my start with playing RPG's WAY back in 1979 (a few of you might remember that white boxed set) and have been Game Mastering since the mid-late '80's. Though I have played D&D and GURPS (and GMed the latter game as well), the vast majority of my experience is with Palladium Games (mainly Robotech and PFRPG) First (and 'Revised') Edition rule-sets.
