Vertex, I respect your efforts and interest relating an easiness of use.

Just in short:
Programming a game is a creative act, too. It is not only the art which makes a game unique and fun, it is the programming as well, and this means, you can't simply reuse old gameplay to make a new game. This means, at least, an artist won't be able to make a game without any programmer.

The templates didn't help me as much to get my own game as the articles and small applications that the Acknex User Magazin (AUM, Link on this page) offers. The templates are IMO too complex to learn from them.
The articles in AUM are small and well explained.
And the initial workshops of GameStudio on the download page give a nice introduction how everything relates to each other and gives a basic understanding of the scripting.

Nonetheless, none of them gives you a fully set of features that everyone would expect in a freely explorable 3D world.
That's probably what you are missing, and the template tries to offer that, but it takes IMO a too complex approach and isn't intuitive, that you could expand it easily.
