RuneScape is actually a fairly complicated game. Young people love to play it and there is actually a lot to learn to fully enjoy it. This book introduces and explains the basics, the various characters and some elements of strategy. It is targeted toward young readers between 9-12 years old and judging by the way I see these kids carrying the book around and the enthusiasm they have for it, it's a hit. When I look through it, I notice that there are a lot of good illustrations and the material is visually well presented. There is also enough text to make it worthwhile, but not overwhelming. This is a nice introduction and reference, if you play RuneScape yourself or you have a son or daughter who does, they will probably love this book.
This book is essential for advancing through the various levels of the game. It may be a bit too simplistic for older teenagers. However, it's a nice fast track to get more competitive in a short time.
