This does sound like an interesting project. Are you planning on keeping the shape of the countries involved or going completely "off the map"? In either case, I have to agree with Vellum that the tutorial section is the place to go for ideas on how to do things mappywise. On the look of what you want, I would suggest the Finished Maps or Cartographer's Choice sections for ideas on style. However I am not sure what you mean by "communism for a soil for the country". I understand the concept, just not what you mean graphicaly. The other concepts in your example are definately workable, and the tuts area is where you can get pointers on how to represent them on the map.

Have fun, and Welcome to the Guild, The Mappiest Place on the Web
