I was disappointed in this guide, due to the lack of detailed strategy. Also, it seemed to gloss over a few of the important areas and treat them like they didn't even exist. Not a good idea.It seemed as though the authors quickly wrote it, without verifying strategy and concepts that they described. I expected much more specific and accurate strategy from an official strategy guide. It sure wasn't worth the money in my opinion.All in all, it was a very unsatisfying book.
