I'm really bad at using the map editor. What I wanted to try doing was to simply combine Invade Earth with Risk: Mars - with space connections between the Moon and Phobos/Deimos.

Problem is that this is nearly impossible without the original map images - I don't know how much time/effort it would take to combine them, but I think it would be pretty fun - at the least, can you make the background image pictures available? It will make map editor work a lot easier.

I can never even figure out how to get the map editor to work properly though.
