Firstly, There is no guarded system. The "Game", which is outlined in the book as this mysterious "system" of self-empowerment seems to me like a seemingly harmonious yet superficial mixture of a lot of different disciplines, such as Psychology, Philosophy, Ethics, social conditioning, and basic entrepreneurial skills, along with some self-help tips (set goals, have a purpose, be responsible, etc) most of which is superficially laid out and pretty intuitive if one can think clearly and has some experience and a decent knowledge of life.
Secondly, The book has some interesting points gleaned from the areas mentioned above, which is essentially what this "System" in the book is all about. These disciplines are probably indispensable to empowering yourself. The more you know, the better you can understand life and act for the benefit of everyone, including yourself. But my problem with this book is that it presents itself as the ultimate guide to the "Game" and that it will "reveal" what has been hidden from you to keep you disempowered, which is not really the case because, again, it's a lot of superficial knowledge of different disciplines mixed up together and presented to the reader as this hot "Game". It only scratches the surface of the disciplines that can actually empower the readers or the "Players" as the book says. It would have been fine, had the author included some valuable resources to educate the readers about the "GAME" and self-empowerment.
Thirdly, The book is filled with cheap, sleazy rhetoric, which is expressed condescendingly about how this book is the only of its kind, and about how all this "Information" is so classified and hard to find elsewhere (Which is not true). The shortcomings of the book are justified by blaming the reader for not having the "GAME" in them. Also, the book is not well-edited. It has numerous spelling and grammar errors. I found this irritating.
Lastly, this book might be interesting to some people, Just be cautious not to fall for the Dunning-Kruger effect, which I sense in the way the author believes his knowledge is uniquely profound and novel.
