Forgive the thread necromancy but, I feel now that Open Grave has released with Vecna's stats, this thread needs resurgence.
My thread is back

With that said, I'm starting to wonder about this so called "market" for good aligned or unaligned campaigns or games that WotC adamantly gives as the reason for excluding good aligned stat blocks and the like. I just don't see how it's possible that a majority of the market cares not for evil aligned campaigns...
You make a clear and very valid point! I also agree that evil campaigns are fun and interesting, and that there is a
giant demand. In fact, last Sunday, my Paladin of Kelemvor said at the table that he'd always been interested in an evil campaign, to which my other players gave resounding "same here"s. And they're a pretty roleplaying-intensive group.
The decision for Wizards to create only good-aligned content for now is, however completely within my understanding. It's not only a business decision to appeal to a wider market, but I would say that the game needs something more like Arcane Power right now than it does Book of Vile Darkness. While it would be great to see these materials, I think they're still down the road a little bit. I truely believe Wizards intends to release evil-aligned materials in the future. Sure, they could have done a better job, maybe putting out one or two Dragon articles already, but for now, adapting the rules isn't too tough.
One thing I would refer you to is the new "Masters of the Planes" article about planar epic destinies. While they note that a "Prince of Hell" wouldn't neccessarily have to be evil, it cerntainly seemed like a sweet hit of evil-aligned content to me.
I hope as well for evil aligned content. I can be patient, however, as I do not believe it is Wizard's intention to not ever release it.
