Hey I have a few ideas around implementing slaves.
First of all I see them as being a resource that could be bought/sold but can be aquired in a 'treasure form'.
Such slaves can be only aquired from natives (albeit in several ways) and sold to Europe at a premium or used in a slave market.
Slaves can be aquired either by buying or by trading e.g. guns/horses with natives, the availability of slaves via this way should be determined from the native chiefs personality traits.
Using a slaver colonist class like a misionary but to recieve slaves (in a treasure-like unit) rather than Converted natives, but be given the slaves at defined periods rather than randomly. Again the effectiveness would be determind by the chief personality. Having a slaving base weakens relations with natives.
Or by simply conquering the native village, so as to get slave unit rather than a converted native which doesnt make sense as you distroyed their life, why should they want to work for you. (On a related side-note I belive if a native gives up a settlement due to culture that should result in you receiving a Converted native)
Or in peace negotiations e.g. you agree for a peace treaty in return for X amount of slaves. These slaves would either be given directly to your capital (in treasure form) or in the closest native settlement to your units.
Slaves can be used in a "Slave Market" line, which instead of effecting any resource directly they increase the % effectiveness like rebel sentiment does, but only for raw materials. I belive this is more correct than having them only effect Hammers, because that is more representative of forced labour whether it be in the cotton fields, construction, mines etc. etc.
During the DoI if you choose freedom then all stock would be changed to indentured servants or Coverted Natives.
Hows that for a first post on a forum
