Got it last night and I must say it is very nice. I haven't played CoC for a couple of editions so I'm not sure what the curent state of the game is, but the d20 version is excellently presented.
The visual design is...interesting. Great to have the full color paintings rather than line drawings, and the skewed columns really do lend to a sense of disorientation, but I'm not sure how easy it will make the book to use as a rules reference.
I'll let you know what my players think after I drop some of these things into my D&D game...hey, the Freeport series is all full of mythos references anyway!
