Is there anyway to make the game world render like an orthogonal view? You'd still have a 3D scene but no apparent depth to the eye.

Try reducing your camera's .arc parameter while simultaneously moving your camera away from the scene. This might be what you want:

(If that link doesn't work, try a search for "three-quarters isometric overhead.")

That seems to be the answer. Thanks.
