Imagine my surprise when I saw an ad for "Dungeons and Dragons and Philosophy", edited by Jon Cogburn and Mark Silcox, scheduled to appear from Open Court Books. Asking around I found out that yes, it'd formerly been a Blackwell concept. So I fumed for a while, and then decided to send a message to one of the editors, to find out what the hell had happened.
Turns out, it's a COMPLETELY DIFFERENT BOOK - compiled some months before Robichaud's, without any open CFP, and first offered to the same publisher. Therefore all search engine uses led to the impression that it's the same volume, and that some authors had been very rudely dropped. Not true. Just synchronicity and some bad manners from one person.
You can find out more about the real book here. I know some really good authors are included, so my hopes for it are very high. I have already pre-ordered myself a copy.
