An epic escape from the boring drudgery of reality, where heroes and villains can be expected to make a huge difference in the world.
Also noteworthy: I'm designing my own system, and while I have yet to make a playtesting packet, I am GM'ing a campaign which is currently serving to help me playtest my game.
My first PnPRPG experience was Warhammer Fantasy Roleplay, in which I was the only one who played a character capable of combat (the other characters included at least two rogues, a hypnotist, a librarian, and two guys who happened to own a boat). My next experience was playing an Iron Kingdoms game with DnD 3.5 rules, in which I played an Ogrun Paladin. After that, I played a Minotaur Monk in a GURPS game. Since then, my characters have gotten... weird. Anyway, I really enjoy PnP RPG's, and, if my schedule allows, I try to participate in at least one game at a time.
