note: this book is not a tutorial on how to use development kits or game creators, but focuses on everything else: the idea, the skills, and the mind set.
This book is so incredibly good, it has hundreds of things to include in your game and is perfectly written. it includes topics about; how to create an experience; elements, themes, ideas, incorporating the player's mind, game mechanics, interfaces, stories, worlds and characters among a bundle of other things.
This book is alot about physcology: your mind towards the game and the player's perspective. it has the potential to make your games more creative a hundred fold and includes detailed analysises and diagrams about everything from creation to teamwork to money. I highly recommend this book, even to people looking to understand the creative process, but espcially to new, and xprienced games designers.
