It might make gameplay sense to have Brazil and Argentina as well to fill up South America?
On that note, it might be interesting to reflect the de-colonization of the modern era: the birth of South Africa, Australia, etc. It might be difficult to create UHVs or UPs for these countries, but perhaps they can be purely AI players unselectable by humans? They would be fairly passive, not expanding beyond their strict historical bounds.
Regarding decolonization. the 2 "Independent" civs don't allow other civ units to pass through their cities and would essentially just block off parts of the the map for gameplay. Having separate civs representing South Africa and Australia etc.. and each with their own leaderheads, would cost too many civ slots.
I had suggested a "union" civic in an earlier post so that a civ such as England in modern times with "union" will represent the United Kingdom and the Commonwealth of Nations countries. Cities outside of the civ's core area (aka, Canadian, Australian South African, other colonies' cities etc...) will require 75% less maintenance, but also produce 75% less commerce, 75% less science, and 90% less production for military units and national wonders. On the bright side, these cities outside of core area would also be much less likely to declare independence.
The chance of cities outside of core area declaring independence will be greatly increased for civs that don't adopt "union" (could kind of historically represent Spain and how it lost its colonies in Philippines etc..). That way, maintaining loose control over colonies through the "union" civic essentially allows you to maintain a large network of cities around the world friendly to your troops at the cost of a large part of the contribution these cities could make to your military production, research and commerce. If you want to control outside of core area cities as direct colonies, the cities would reap in much more commerce, science and production, however at the cost that those cities are much more likely to declare independence even if your stability is not uber low.
One other thing that I've always thought strange: in the 600AD scenario, why has India collapsed into independent states? it prevents the English or the Arabs vassalizing the subcontinent, which in either case would be historically quite accurate. More importantly, there is no chance of an independent India in the modern era.
I think India in RFC does respawn in the modern era. Leoreth might be planning on adding some excitement to post medieval India with the possible inclusion of a Mughal respawn.
You mean the Chi Rho / labarum symbol? What's wrong with it?
Sorry, I was completely unclear. I was wondering if Rome will still keep that decal, which I had always associated more with the Eastern rather than Western Roman Empire. Rhye had, for the 3000BC start, desired for Rome to represent both the Roman and Byzantine Empires, so I'm guessing that's why he had the Chi Rho decal for the Rome civ.
