Not something I would like to do. I don't need any money to write another WYRM game, but I need time, motivation and inspiration. And I don't think a universal WYRM game would be any fun. We now have a couple of WR&M variants out there. That's enough material so that basically everyone can design his or her version of WR&M without the need for a universal corebook.
I understand where you are coming from. My thoughts were more towards bringing in more setting-devoted players with a quick, easy way for them to assimilate those settings into easier rules. My initial thoughts were focused on play-by-post gaming. It's much easier to have a generic book for bringing said people into the system, instead of designing new rules every time I try to run them on something away from fantasy.
Back to the OT, I dig the minis. The Honest Abe seems well-timed, especially with Vampire Hunter on the way.
A main problem with a universal WYRM game is that it's just not easily done. The idea behind the system is that it uses archetypes from a genre as attributes. You can't make this universal. And when the SF version of WYRM is done, there will be a WYRM game for fantasy, pulp, cyberpunk and space opera/SF. It should be easy to extrapolate to other settings then.
