UPDATE: Argentina
Argentina
Leader 01: Eva Perón
Leader 02: Marcelo Torcuato de Alvear
Start bias: coast, not far from tundra
UA: Paris of South America - Cultural buildings and wonders have double slots for Great Works when built in the capital. When in a Golden or Heroic Age, Argentine cities receive +5% growth for each civilization that Argentina knows and is in a Dark Age, and these civilizations get -5% growth.
Eva Perón' ability: La Dama de los Descamisados - Specialists in Industrial Zones are called "Descamisados" and they grant +2 food, +3 production, +3 culture and +1 loyalty. It allows you to start Evita's Speech city project.
Evita's Speech: cannot be done in more than one city at the same time and can only be done in cities that have Industrial Zone. When active, grants culture and +1 amenity. Upon completion, all Descamisados in the city generate +100% food, production, culture and loyalty over the next 10 turns. This project cannot be done twice in a row in the same city.
Marcelo Torcuato de Alvear' ability: República Radical - International trade routes receive +0.5 gold for each improvement of bonus resource in the origin city. This bonus is doubled during Golden or Heroic Ages.
Unique improvement: Saladero
Available in Mass Production
Can only be built on flat land (except desert and snow).
Cannot be built adjacent to another one.
+1 food
+2 production
+2 gold
+1 extra production and +1 extra gold for each adjacent cow pasture.
International trade routes receive +2 gold for every Saladero in the origin city.
Unique unit: Gaucho - replaces Cavalry. Weaker than the Cavalry (55 combat strength instead of 62). Has 3 charges to build pastures or farms. When a Gaucho builds a pasture or a farm, small boosts of culture and GWAM points are generated.
I made some modifications to my design of Argentina to not be such a blatant cultural civilization. The biggest one is its new unique infrastructure, Saladero now reflects the great importance that the livestock sector has played in Argentina's economy. Its civ ability now more realistically reflects the migratory boost the country enjoyed during periods of great prosperity (or golden ages, if that's what you prefer to call them). Also, I improved Gaucho - now the unique unit has three building charges instead of two. In addition, I removed some bonuses from Evita's abilities. Finally, I added a new leader - Marcelo Torcuato de Alvear. What differentiates him from Evita is that, while the latter encourages its citizens to be more productive for the country, the first will seek the commodity trade to enrich the nation.
