If you are aspiring to learn TGE, the Torque Game Engine from [...] then buy this book right this moment! It's well written, and covers the most awesome game development tool there is: Torque.
My only gripe is that it's super-specialized to the particular tools on the CD. For example there is 14 pages on "Ultraedit 32", a Windows programmer's editor. And Milkshape is used instead of Blender for character modeling. But, OTO that's one of the nice aspects of the book it's "All in One". Like the swiss-army-knife of game development.
