Burning Wheel?
I've been sitting on the burning wheel books a while, but never got the chance to actually play them. I'm not really confident enough in my knowledge of the system to run it, but I'd be really interested in creating a player for one. I'd be cool with solo, group, sandbox, pretty much however a GM wanted to do it, as long as the plot sounded interesting. (Chances are I'm gonna dig the plot, I'm not super picky)
So, if anyone is running a game with this system or wants to start one, I'd be up for it. :)
