I have several years of serious RP experience, though I never played in the planescape setting (unless you count Planescape Torment). I'm open to any game, and prefer in-depth character development over hack&slash. I'm also fond of trying out original character concepts, as well as exotic, non-humanoid physiques to match... But I don't really mind playing something as mundane as a human, as long as I give him or her a valuable personality.

check out "Devious Machinations". Its a freeform, meaning you don't have to have a character with actual stats or anything, just write a post to advance the story a little farther. Anybody can join in, add a character or two, move the narative a little further, and let the creative juices flow!
