I already did. I've never used dragons before in a game, and thought I was buying this to be a conversation piece or coffee table book. So far, though, I'm remarkably interested in what I've read!
Have it. After what I consider a lackluster performance from the other post-revision supplements to date (underdark, mini handbook, BoED), I really must say I was pleasantly surprised by this one. Very nice.
Bought it already. It's on the coffeetable awaiting my reading eyes. Had to finish Minis Handbook first, and about a ton of Scarred Lands stuff. New jobs really chew up your reading time... but hey, they buy more books!
