Free Cities is a text-based slave management game made in Twine 2. The player character buys, sells, trains, uses and transforms a stable of slaves. Most of the standard slave fetishes are present, but please note that the game takes a more realistic approach towards slavery, meaning that non-consensual content is a significant part of what's present.
There isn't much plot to this game, as it is an open ended slave management sim, you are free to do as you choose, and be the slave master you want to be. The number of customization options allows (much better than the earlier versions), allows the player to set up the game to their liking, in term of the player character, the slaves, and the available content.
