I really like this game, as I've noted in previous posts. Unfortunately, the main publisher has not been able to publish anything other than the rulebook and Morgansfort (both of which are excellent). I kinda wish some of the supplements that are currently on the website could get finalized and put into print. I do believe that it was a mistake selling the books at cost.
There's no reason that a publisher should not make money from his books. There is a lot of work involved in getting a book finalized and into print, and doing it for free, while really cool, is not something that an author is going to do for too long. It's just not worth the effort, especially considering the majority of publishers do this as a side gig. I'd hate to come home from a long day of work to spend 3 or 4 hours working on a supplement to a game, if I knew I wasn't going to make any money on it. And I think it shows when you compare publishers and how they charge. Guys who charge more and make a profit publish more books. Guys who publish at cost put out a couple books and stop. Good intentions only last so long, unfortunately.
(Of course, when I win the Powerball, I'll be funding several publishers so they can work full time on games :)).
