Found a link to this game a few days back, the initial alpha release was just a couple of weeks ago:
http://freecitiesblog.blogspot.com/It's under heavy development, but even as an alpha it has a reasonable amount of content and it's hard to find any glaring bugs. It's text-based and there are no images, and it is based on HTML/Javascript so it runs in a browser, but it's well constructed.
It's a text-based management/strategy slave training game set in a post-apocalyptic future where the more privileged people live in advanced arcology habitats. As the player you come into ownership of one of these arcologies, living at the top and starting with 1-3 random slaves depending on the start you choose. You gradually train them to be more obedient and can choose from various things for them to do each week, some earning money such as whoring and some improving your reputation. Each week there is a high chance for random events, which can also be entertaining.
A long list of traits is stored for each slave, and the traits can be changed by various things. You can buy new random slaves and even eventually have the possibility to buy combinations of mother/daughter, sister/sister, and twins.
There are a list of piercings and tattoos you can make them get, and you even have an advanced surgery room available for various surgical procedures such as breast, butt, and lip implants, liposuction for hourglass figure, pro-lactation drugs, and even more drastic and unfortunate surgeries like amputation or lobotomy.
There is what I'd normally consider an unfortunate focus on shemales, but thankfully there's an option when starting the game to reduce the frequency of them showing up, and of course it's up to you which slaves you choose to buy and sell.
Overall, I wasn't expecting much after I found out it was a text-only game, but it ended up greatly exceeded my expectations. Highly recommended.
