I really like Cephistokles 'New Gameplay Europe' map (
http://warlight.net/Map?ID=6821), so I made a similar one based off my own World Big map.
Basically the idea is no bonuses for territory groupings, instead every territory has it's own income. It does change the game dynamics quite a bit, a lot less tactics are involved - but on the other hand it's great for roleplaying and diplomacy.
The map is done, all that is left is actually assigning a value to each territory. This is a lot of work since I want it to be realistic, based on population, GDP and natural resources. Gonna get started on this in a few days, with the trusted help of wikipedia.
The general idea is:
1 army bonus base for every territory
+1 army bonus for every 10 million inhabitants (700 total for the world)
+1 army bonus for every 100 billion GDP (700 total for the world)
+1 army bonus for every 1% of the world's estimated resources of Oil, Gas, Coal, Iron, Uranium and Gold (600 total)
All these values are approximate.
So as examples
US state of New York: +1 base, 1156 GDP = +11, 19,5 million inhabitants = +2 (rounded up), TOTAL +14
Kuwait: +1 base, 9% of the world's oil = +9, 3,5 million inhabitants = +0 and a GDP of 160 billion = +1, TOTAL +11
Tunisia: +1 base, 10 million inhabitants +1, 100 billion GDP +1, TOTAL +3
Since I did these quickly maybe I missed some resources, those require some research.
Questions:
Any other important resource you think I should include?
Do you think bonuses should have diminishing returns?
Suggestions welcome.
