Query: Good book for Game Design collection

If you are serious about designing games, you probably have several books already on game design. This book is a valuable addition to such a collection in that it offers information other books lack, especially with regard to scriptwriting. For a profesisonal and novice alike, being able to describe even a single level in a linear fasion depicting the frame by frame action is mandatory if you have any hope of making a hit title. The book is worth the price for the scripts included alone. This book offers some of the best scripts from published games I have ever seen. Although part of the book is an "ad" for different software packages, for those not familiar with the options, it is a nice addition. On the down side, I thought more effort should have been given to the various documents required to complete the design (brief, TDR, TDD, etc.) since all are required to complete a real game.
