At first glance, a thought comes to your head - "Wouldn't it be cool to create your very own video game!" I work for the Video Game publisher Vatical Entertainment and believe me, this is anything but easy. The one program, Genesis 3D, can be downloaded for free at genesis3d.com, and the book tells you nothing accept a few interviews with publishers. The documentation is just short c++ references to the source code in the engine which you wouldn't be able to understand without an extensive knowledge of c++ much less know how to use it to make a game. It doesn't come with a 3-d modeler, which you need, just an animator which I believe you can also get for free. So in short, even though it looks and sounds great, you would never be able to create a game using it.
