I'm currently working on a mod that replaces civilization traits with unique powers, much like Rhye's and Fall of Civilization already does. The problem seems to be coming up with ideas... I'm no historian, so I don't really know what powers to give to a lot of civilizations. Here's what I have so far. The ones in italics are already decided, but you can still comment on them if you feel they are imbalanced or ahistorical. Please note that I want to try to keep my ideas original and not steal from RFC wherever possible. America All cities +2 happiness OR American culture in enemy cities has a much greater effect (in terms of unhappiness and revolt chance) Arabia State religion spreads faster Aztec Can always hurry production with population OR +2 food, production and commerce in every city for every vassal Babylon -50% civic upkeep Byzantium Some kind of bonus for attacking a city that was once yours OR Something to do with culture Carthage All military units start with +2 experience OR +25% military unit production Celts +0.5 happiness for all forests and jungles near a city (maybe +1 production instead?) China -25% food required for city growth Egypt +50% wonder production England +50% naval unit production OR Lower maintenance cost for colonial cities OR Something else? Ethiopia More city defense from culture France +25% culture in all cities Germany Upgrades cost half price Greece +100% Great People birth rate OR All cities +2 Great People points Holy Roman Empire ? Inca All units can move through mountains India No anarchy in revolutions OR +1 happiness for each non-state religion in a city Japan Enemy culture spreads more slowly in Japanese territory OR Technologies already researched by other civilizations cost less Khmer All units start with Woodsman I and Woodsman II Korea All units start with City Defense I and City Defense II Mail +1 trade route in every city Maya ? Mongolia Lower maintenance cost for military units Native America +1 food from plains Netherlands +100% trade route yield for coastal cities Ottomans -75% vassal maintenance Persia No resistance in conquered cities Portugal All naval units receive an extra movement point Rome +25% building build speed OR Workers build improvements 50% faster Russia All tiles produce at least 1 food OR Double production speed of workers and settlers Spain Cities with state religion receive +25% production OR All units +50% strength versus obsolete units (unfair?) Sumeria Farms produce +1 food Viking +100% gold earned from pillaging and city capture Zulu Enemy culture does not spread into Zulu cities (unfair?) OR Majority of foreign culture removed on city capture As you can see, this list is nowhere near complete, so any feedback or suggestions would be greatly appreciated. Thanks! PS: The numbers can be tweaked later, after I have a power for each civilization. For now, I just need to get some ideas rolling.
