The World Of Prime game materials are now available on DriveThruRPG. In their first day there they've gotten between 40 and 60 downloads each, which is a really good number. I'm hoping the weekend will be even better; but after that, they won't be new, so it should start to tail off.
Best of all, I've actually gotten some reviews. Two five-stars of Ye Olde Shoppe, and one three-star of Hives of Formia. The low rating seems to be because my adventure settings aren't very scripted; it's more of a resource for a DM to generate encounters than a series of pre-programmed encounters. I've been thinking about making some actual modules, in the old style, but I want to get all of the Kingdom and the surrounding areas down first.
The high ratings are because Ye Olde Shoppe is what every DM wants. If all I did was put every price from the PHB and the DMG in one book, with an index, it would have been worth 4 stars. At least. The Bard of Valiant compared it to Aurora's Whole Realms Catalog, which is high praise.
I can't say enough good things about DriveThruRPG. Their tool interfaces are better than Lulu's, and their staff is incredibly quick to help. I've put SotBL up at their sister site DriveThruFantasy as an e-book. Too bad they don't do POD...
