This is a lovely idea, I wish they would do it, but two problems. 1) This would require Chris to coordinate signing of books and shipping them out. I have no doubt he never wants to do that again, especially because most people who likely want the actual book over a dungeon room don't play his game any longer - i.e., not much benefit for him other than a warm fuzzy that obligations were fulfilled. The world does not run on warm fuzzies though. 2) This would cost money that Catnip Games either does not wish to spend or does not have to spend on an old commitment. And so it won't happen.
