Thos book is a collection of wisdom, aimed to provide an overall view of what you need to consider to write your own MMO. There is no code and the articles do not go too deep, which is not a bad thing, because they provide easy to understand contents. So before writing any code, read a related article, avoid pitfalls and only then start writing. I have been reading this book for several months, over and over and I still love it. There is no need to read the articles in any particular order and each reading session can be as short as 30 min. and still provide good knowledge to you. This book is a must have on your bookshelf if you are serious about MMO games and use other people's knowledge to shorten you own development cycle. I like it so much, I just bought the 2nd edition, which looks very promising, too. And dear author(s), if you write a book with a framework, I'll buy that one, too, without any doubt.
