Having never owned anything Eberron before I am so far rating the book "Good.". I am realy enjoying the bestiary (the primary reason I bought the book), the lord of blades is really interesting and there a quite a few high CR options. I am also enjoying the alternate cosmology / faiths and Sharn seems interesting. There has been a bit of debate about the art in this thread, but it seems like pretty standard D&D fair to me. Some OK, some good, and some really good. I think both
@Ruin Explorer and
@Parmandur might have been a bit hyperbolic in their reactions.
