Fire and Forget
Simplified control system by giving Golems AI to do the most logical action, rather than coming to rest and waiting for another command. In this example one tree selection (followed by repeat) lets you build your first army. You are free to run around shooting (badly in my case :) ) while your army is built.
They mud golems return to you after they are finished, where you could simply make them mine again.
And that voice is VERY much temporary. As you only want to record voice talent once, I have made system to automatically convert the text to speech in the build process using the Microsoft 'Text to Speech' library. This means you can have place holder text whenever you change or add a hint or message, without a visit to the microphone.
