I'm a big fan of this author, his other books on game engines or tools are outstanding. This one however fails to meet the criteria of his other books.
This book was a big dissapointment. It is just as the other user said. It's a basic manual for the Realm Crafter Professional edition, and has about 3 tutorials. These include, but are not limited too how to add media to your project, and how to make terrain using a heightmap.
This book is something the developers should have released with Realm Crafter Pro. So instead this acts well as a user manual that should be given to the user upon purchase of Realm Crafter.
I will say if you just picked up Realm Crafter Pro, and would like a detailed explanation of the tools and tabs included in Realm Crafter, this book MIGHT be for you. However most users will already understand the tabs and basic engine functions 'out of the box'.
What this book should of done was show you how to drop a character onto the terrain, set up a basic quest, and maybe kill a few monsters and turn the quest in. That would of made this book at least half way worth the purchase price.
