Respectfully, you’re wrong about how slavery is presented in Dark Sun. It is very much chattel slavery. Though it is not based on race...except when it is...muls and half-giants...cough. Slaves are treated as nothing more than property and the children of slaves are also slaves, two of the key markers for chattel slavery.
To quote: “A person can become a slave in one of three ways: by being born a slave, by being captured during a war or other armed conflict, or by being sold into slavery for committing some crime or failing to pay one's debts.”
Further, the text repeatedly refers to slaves as being owned by and the property of their masters.
So the version I was talking about would not be a change to how Dark Sun presented slavery. It would be a continuation.
Respectfully, you didn't read what I wrote because you were too busy getting ready to argue. Here, let me repeat my summation with the appropriate bolding:
TLDR; I wouldn't change the nature of the Dark Sun setting vis-a-vis slavery to make it reflect American, instead of Roman, antecedents. All slavery is bad, but American race-based chattel slavery is, you know, really bad and doesn't make for a fun & diverse game. IMO.
At the point in time when you read, and can respond, to what I wrote, then you will understand that this was modeled after Roman slavery- by birth, by conquest, or by operation of law (debt or judgment).
Not American RACE-BASED chattel slavery.
