Well in a sudden frenzy of activity I have actually finished and published Underworld:

How exciting. Only now I live in fear of having made a mistake in it somewhere.  Sadly it is quite expensive for a card game at $69.99 but it does contain 500+ cards.

Now I can work on finishing the Print&Play version, followed by some expansion decks.  Then I can finish work on Gobbos, my next exciting game.

And the PDF is now: http://rpg.drivethrustuff.com/index.php?manufacturers_id=3986&term=the%2520aus
