How do I create graphics?

What are the different areas and parts of the game that need bitmap graphics created?

If you want to have a go at buildings then give this zip file a look.... it contains some basic buildings for the game.
the XML file describes how they are built and you will see the images are comprised of a roof, repeating-middle-section and base...
quite straightforward...

you can more or less create any form of graphics imaginable that you want in the game and then we can either add them in or write code/plugins to add them in and make them :do stuff:.
