At $100, the Torque Game Engine (TGE) is quite a deal. It is a sophisticated engine that provides a great deal of assistance in handling the basic operation of a game while leaving you the opportunity to create the design and concept you want without undue restrictions.This book is an interesting cross between a reference text and a tutorial. Most of the book is in reference style. That is it talks about the various features, what they do, how to use them and so on. It is aimed at the individual developer or the small team, or it could be used by a newcommer in a larger organization.Finally, after the software is described in this reference format, the author goes into a tutorial mode to lead the reader through the writing of a fairly simple game. In this section the reader finally gets to see what the various parts he has learned about actually do in a real world (although simple) application.The CD included with the book includes some additional information as well as a Torque Demo Installer.
