i was reading the newspaper, en then i get an idea: a continental war. Every continent (Europe, Asia,Africa etc.) gets their own army and fight each other
You could get the Attack and Attack Expansion game from Eagle Games and use that for your map and forces. You have infantry, tanks, artillery, aircraft, battleships, aircraft carriers, destroyers, and submarines. The combat system works considerably differently from A&A, and depending on whether you use the basic games rules or the Deluxe Expansion rules, production points work differently too, along with tech development. I prefer the original Attack Expansion, and I am running a game using a mixture of the basic game, original Expansion, and the Deluxe expansion. Works pretty well.
And Australia in not one territory but 5.
