I've got like 4 prestige classes for my Pariah class, a few Base classes to finish, and, oh, two whole completely new game systems.
On is basically a cross between Zen and Sliders (the TV show); I'm stalled with this one, I'm afraid (I can't decide on basic mechanics, though I have how everything else will work down... Backwards, I know...)
And the other is a game where you play as a Wuxia Monk. Not an Eastern monk, though; I'm talking Western-style friars. The basic setting assumption is that you are playing in the time of the three popes, and Satan has managed to open a portal to Earth.
Play a Jesuit, get knowledge powers; play a Gregorian, and essentially be a Bard; that kinda thing.
