As of tonight, there are 170 maps on the blog available under a free commercial license. Because there’s been some demand for it, I’ve assembled all the commercial maps into one package for easy download from RPGnow for $20.
Note that there is NOTHING in this package that you can’t get by surfing through the site and grabbing the commercial-licensed maps. It exists for those people who want (a) a collection of all the commercial maps to date and/or (b) feel better when they pay for these maps.

Thank you! Happy to throw some money your way in exchange for this convenient collection!
