Yesterday I gave a speech at the Open Up conference about creating an Open Source world. The setting of Virtuso is a wiki-- should we get funded (Virtuoso Kickstarter), we'll be opening up the Virtuoso Compendium, a place for you to rewrite the history of the setting as you see fit.
And because we're a CC licensed book, you can feel free to sell whatever you make. Board game, spin-off comic, jewelery, you name it, we'll provide an Etsy market for you and a built in fanbase.
