I can just say... WOW! Way better than what I expected! I hoped for something like this, but wasn't expecting it at all. The book is looking great and has relief on the cover. You can remove to small paper on it saying "Diablo 3" wich makes it look like a nice ancient demon book. The edges of the pages have a kind of damaged style, wich makes them look old.
I really really like it! Thank you Blizzard, this is a true book of any Diablo fan! Every game's collector books should be as nice as this one.
