This game has so much potential to be a big hit for its gameplay as much as adult content. Since the game dev seems to browse this thread I would like to offer a few suggestions:
One of the chief problems I have with this game is just how unattractive the "dolls" are right now.
Instead of having one lumpfish face which is then randomized to high heaven, I think it would be better to create 4-5 (for starters) different face geometries which randomization parameters then act upon. This is the principle that I think is used by certain popular "pretty-fying" mods for games like Skyrim. For example:
You must be registered to see the links
Another thing I would really like to see is some more makeup, eye-shadowing and color on the girls' faces.
Secondly I don't like the way the market works right now. First virgins are too common, you can literally get them for pebbles whereas it should be a precious and rare commodity in the universe that rather artificially increases the value of a slave severalfold (as ridiculous as it may seem to some people...well this is how actual slave markets that exist in our world assess their merchandise). Second I don't like how the player has access to all slaving markets from the start, such that there's little incentive to use anything but the most expensive one since the price difference between them isn't that great. Compare that with Free Cities where top level slaves cost orders of magnitude more.
You should start with access to common low end raiders markets and then unlock new ones with prestige (selling far far more expensive, and I should say even overpriced slaves). Of course at the top end, there should be quests that allow you to pursue unique catches such as princesses, bounty hunters, heroines, singers, celebrities and other famous girls that would greatly add to your station's appeal and bring in cartloads of money due to their looks and fame. This would make slave acquisition a much more interesting task to pursue.
