This book is what most other books on the subject should be!At least at the beginer's level.What excited my curiosity is the simplicity and elegance of the author's writing. Using C# as his language resulted to an elegant engine design where other books fill space with windows initialization and other trivial tasks.It allows the reader to concentrate on the engine rather on the operating system. The only let down is the lack of a CD with the code although it can be found on the web site.At the end of the book the reader will have a simple object oriented extendable engine with console,gui,3d rendering,audio,simple ai & physics.Networking is mentioned and discussed in very brief manner.
Could well become a classic!
Overall an excellent starter book on game engines!!!
