There isn’t.
Will there be?
Not from me, since I lack the skills necessary for RPG development. And that’s unlikely to change unless I somehow come into vast quantities of money – the kind that would enable me to go to, say, Jenna Moran (to pick someone who could do justice to the universe) with something to back up the requisite begging, pleading, and asking nicely.
Awww.
That said, if anyone (or any company) has some experience with producing this sort of thing and is willing to work with me on this, I am perfectly willing to talk about a license. Contact me!
