Yeah, I'm *really* interested in Urban Fantasy as a genre (and it still seems to be a trendy genre, if In Nomine, Vampire, Exalted, Unknown Armies, etc. are any indication), and I'd love to see it treated well. I suspect that trying to coerce more than a passing reference to Urban Fantasy into the Fantasy Hero book would cause a lot of loss of focus, but I'd still really love to see it.
Please, please, please consider an Urban Fantasy sub-genre book!
