Many of us have played some edition of a Star Wars RPG; but what other RPG systems have you played? What are your favorites?
I've played a few campaigns (in my group a campaign is usually a few months worth of gaming at least, 5-15 sessions or so) of World of Darkness (Mage and Vampire), got a number of sessions into an Exalted campaign that's currently on hiatus (we'll probably get back to it at some point), and plenty of DnD 3.5 and 4e. I've run 2 sessions of Dread (an indie RPG that I'm absolutely in love with, read about it here:
http://www.rpg.net/reviews/archive/11/11974.phtml), and I've run some Spycraft 1.0. I've also run a Call of Cthulhu 6th edition campaign.
Recently I've picked up a number of books for pretty cheap. I got Mutants and Masterminds 3e, The Authority, Ars Magica, and have The Dresden Files RPG on the way. I also picked up Cthulhu Dark Ages at GenCon. I haven't gotten a chance to actually play any of these yet, but they all look pretty good. Ars Magica has one of my favorite magic systems ever, but the character creating is very heavy and too in-depth for my taste; I'm thinking about porting the magic system over to FATE to see how that works.
