Right now at All Things Fun! in West Berlin, NJ, I'm playing a bard named Uhtred in a Castles & Crusades campaign. I'm also involved in a Savage Worlds game set on a world called Proton (it's a "weird tech/mad scientist" campaign).
I'm also occasionally playing in a Pathfinder "pick-up" game with some other folks whenever we can get together (at someone's house, not at a game store).
Other campaigns I've played in have included:
Savage World of Solomon Kane: My friend Bill runs the Solomon Kane setting for the Savage Worlds game system at All Things Fun!
Wednesday Night Castles & Crusades: City State of the Invincible Overlord at All Things Fun! in West Berlin, NJ
(We play this whenever GM Rich is in town)
