I like this system, and the options interest me. I've tried doing some research on MotW, and assume the specifics - as you said in the OP - will be elaborated on further after interest is shown. I like how this is driven more by character and story than a dozen skill checks and dice rolls.

In terms of characters, I'm torn between the Mundane (which sounds like it can be humorous), the Monstrous (which seems like it could have some character development potential), and the Professional (which, I dunno, sounds like it could be cool).
