Query: This isn't a book.

Getting this book is a lot like googling "Game Design Article" - you have to do a lot of sifting of your own. Many of these articles aren't even about game design, they're just some story that happens to involve a videogame. Plenty of hot-air articles in here, and the occasional quality article. Why someone would want to have this when they have an internet connection is beyond me. Just go browse Gamasutra and you'll get the same experience.
