S. John Ross has launched a Kickstarter project to develop a library of free Risus adventures. He's setting a low pledge target (that he's already hit) and will add production values and pre-fund future releases if the target is exceeded by a fair amount (which I expect it will be). These adventures are expected to be approximately 6-8 pages worth of of awesome - the kind of awesome that you'd expect from the author of Risus: The Anything RPG.
As an aside, I really like the idea that these will be free to the public once they are funded. Yes, backers get some not-to-be-sneezed-at bennies (such as advance copies, designer notes, etc). But mostly, you'll get the satisfaction of getting more of S. John's work out there for the world to enjoy.
So get thee to the Kickstarter and make a pledge today!
UPDATE: Wow, S. John blew past his target and then some. Word from the man is at the page count for the initial adventure has likely doubled.
