Of all the computer books that I have read, this is the 1st that prompt me to write a 1star review.
1.Lacking or essentially lacking a lot of essential topics, such as character animation/customization(the game in this book doesn't even have a single character nor enemies nor even an animal in it), rigidbody, realistic physic system, particle system to create special effect like realistic fire/water/explosion etc. and many unity effects such as clothing. Most of these are present in almost every modern games.
2.contains ridiculously little information for a book this thick. This book included a lot of unseless pictures, and just waste a lot of pages asking you to click this and click that like an idiot, rather than explaining the reasons. (e.g. the author ask you to "save the script"+"click play" for like a few thousand times within this book after each small change, and with all the blank lines in between "save the scirpt" and "click play" etc. accounted for the thickness of this book. I bet even the most idiotic person in the world would understand the need to "save" and "click play" automatically after the hundred time that the author wrote that down explicitly)
3.The author just expect you to copy and paste a lot of code into your game, and didn't even borthered to try to explain them, nor expect you to understand, which severely limited your ability to add your own functionality into the code.
4.Doesn't care much about efficency of performance, nor give you enough guidance to optimise your game, such as not telling you the significant performance difference, of e.g. changing the size of a mesh within other 3d modelling software, or within the importer, or the scaling option.
5.No suggested reading at all, not even one. a few suggested books/reading/webpage on each topics, and on all the topics that this book left out, should be included in every textbook like this to help readers interested in a specific topic.
6.Ridiculous download time for the companion file. At the time of writing, you are expected to maintain like 25-30hours of stable, uninterrupted, continuous internet connection to download it, with its slow download speed, and without an ability to resume download once the download is interrupted.
7. Printing quality is not so good.
I know that this is a beginner books and couldn't possibly include all the topics, but this book didn't even borthered offer a way to get you started, and many topics that are left out should be included in a beginner text anyway.
