You might think that Mojang have produced this Minecraft book as a hardcover for the prestige, however I think they are aware that this book is required to be hard-wearing, that this book will become a part of your home's Minicraft world. It's going to see a lot of action. That also explains why the pages are so thick - tear and rip resistant. This book provides not just the opportunity to build an epic fortress, but also includes a village (in less detail) and a dungeon. You also get to fill it with redstone traps - ideal for evil lords everywhere!
The exploded diagrams are a great approach, for they make it clear on how to build what is a complex structure. My nine year old Micecraft addict built the initial turret then found it a little to tough to proceed. The ability of builders will vary and if this is a present for children be prepared to pitch in and give a little help (or have someone who can) - it's times like these that local multiplayer can really help. However you get the fortress built, it's going to be the envy of other players in your world.
The overall quality is excellent. I've mentioned the page quality above, however the binding is also very good and the pages are full of information and very clear text and illustrations. Despite the amount of information presented, it is always clear to see, well spaced with a very easy to read font.
Overall, this is a great book, which needs a little patience but delivers an awesome result.
