well the Game i wouldnt class as a PUA book, though certenly recommeded reading to get an idea of what the game is.
i beleive there were some examples of other Guru's play styles in there, Mystery's attacking subtly
David dealanglo's bussiness and methodical approach
Ross jefferier's hypnotyism and psycholohy
roosh's personal appearnce and aura approach
gamblers fame and open approach
neil strauss's whatever works deep research approach
there are plenty of otehr guru's barely touched upon in the book The game
but plenty of Gurus and Mpua's out there, and by no means do you follow their game to the letter.b ut make your own personal game based of your own personal strengths and weaknesses. i bough up every refrenced to any Gurua nd Mpua in The game and in the books bought there after, my pile is along the lines of 30-40 books. of differnt aurthors and Guru's, tactics, reading, psychology, NLP, laws of power, art of seduction, pub magic tricks, cold reading, palm reading, memory retention, confidense building books, on and on and on
what i recommend is that you look at yourself and decided what your personal qualities that shine are, and if you feel tehrea re too few, or hard to tell what those qualaties are, think to yourself, what sort of PUA you'd like to be, how you'd feel the best way to approach women are, and then concentrate on that. be in in style and grace, humour and spontinarity, mystery and intruge, power and dominace, confidense and diciplined, whatever combination of howeever many, you need to dicide what it is you want to be, and how you will do that. you cant just read ab ook ask afew questions go out for afew months and lay afew girls and be considered a PUA, you must know exacly who you are, what you are, and how you did it.
know the skills you possess, the abilities you have, and your own personal game. we do not proceed as a speicies by coping other peoples ideas and sticking to them. but by adding to them and perfecting it in our own way. so that someone will do the same to you when you teach them.
when you know what it is you want and are and can do. then read those books, read all the books if you wish, becasue you already know what you want to take from them(and getting anything extra will enver hurt) you know what to apply to your game and what just to have incase you want to try something new, or fix something that doesnt work.
im not saying read everything do everyhting, im sayi ng read everyth ing and use what works personally for you. thats what makes a Pick up artist and artist. becasue hes perfected his art.
best of luck
