A Civilization 5 wish I'd like to see is a big Earth Map that represents the Civs of the world today in terms of their current borders. Basically, 18 civs start out but only the remaining civs between 1800AD - 2050AD remain at the end of the game. Therefore some civs would transform or attain their current borders. For example, the Americans would have all of North America except for Montezuma and Mexico. Montezuma would not send settlers to where Seattle or Chicago is and George Washington would not send settlers overseas or to South America. The same applies to India where they would be confined to the Indian continent, the Japanese to the islands, Saladin to the Arab pennisula.... etc. No other civ would settle beyond their own borders. Areas such as Australia, Canada, Phillipines, Vietnam, would be settle by barbarians unless their is an Australia & Canada, Vietnamese & Phillipine Civilization in the Civ 5. Otherwise different barbarian civs for each continent would exist.
