My 9 year old and I played a cooperative version of this and quite enjoyed it.
Traditionally, when it comes to slavery, the pirates were the good guys. Pirates did a lot of "stealing property" that was actually freeing slaves.
The normal way to play involves fighting pirates. However, with the rules-lite nature of the Micro RPG, it was easy to invert that part of the narrative.
We were pirates coming to liberate treasure and slaves from a cop-infested ship intent to "return stolen property."
