An introductory book about Game Design. The first part focuses on general tips about Game Design (storytelling, balancing, etc.). The second part is dedicated to a presentation of the different videogames genres. The first part of the book is clearly the most interesting one, as the second part is both aging fast and not as detailed as we could have expected. Please note that this book received three updates greatly extending the part about Game Design tips, titled "Fundamentals of Game Design."
