Alrighteous! I've been working on an interesting idea in order to allow some sort of Slavery into the game... Still on a Beta level, testing will be appreciated, specially for suggestions and balance issues... Click on the Chart Image to download: Features: New Elements: Slave Worker: A special Slave unit, which may not be produced through normal means. The slave has faster work rate than the normal worker, and may be expended to rush production in a city. However, it adds Unhappiness, and its health drops each turn. Slave Prison (Building): May only be built on Occupied cities. It has 3 Slave Slots, which allow generation toward Slave Workers. May not be built if a Courthouse is built and doesnt remove Unhappiness. Becomes obsolete upon discovery of Radio. Slave (Citizen): Yields +3 Production, and +2 Gold. Works towards generation of Slave Workers. How to get Slaves? The main way of getting slaves is by conquering a city. Once you conquer a city you may be able of building a Slave Prison, and then use Slave Citizens. Using Slave Citizens will work towards generating Slave Workers. This way you can assure yourself to get Slaves, at the price of unhappiness, however. You may sell the Slave Prison if you want to switch to a Courthouse. Another way is capturing another players Settlers or Workers. Instead of becoming simply workers, they become Slaves. More ways of getting slaves are planned for future releases. How to free or stop using Slaves? If you own a Slave Prison, you may sell it. Once you do, build a Courthouse and stop thinking about slaves and their Unhappiness. If you are at war with an enemy, and capture their Slave, you will technically free him, transforming him into a Worker. Freed Workers work faster than normal workers but slower than Slaves. You may also upgrade a Slave to a Worker with gold. This requires a costy sum of gold however. After researching Radio, you will lose the benefits of the Slave Prison. Screenshots: Spoiler : TODO LIST: Find a way of changing the Worker adquired from bullying a city-state to a Slave. Find ways for AI to make use of Slaves (they mostly puppet cities, so...) Find ways of making AI hate you more if you use Slaves? Maybe? Add Slaves to some policies and/or Wonders Find a way of changing the "A Slave was born" notification, to make it a bit less happy than the Great Person notification, and using another sound... (Post BNW) See if a World Congress resolution banning Slaves is possible to mod.
