For me that would be probably "theming" your business. But it's hard to explain. Something like setting a "house rules" for both girls and customers and promoting that. So there could be a one building where all girls all proper and elegant, and any ungentlemanly behavior there is not tolerated, while on the other street you could run a dirty whorehouse where anyone can be rough to the poor girls as they please. And if what type of girls are together could matter somehow.
Few days ago when discussing the new theme for PyTFall (the bright map), Dark mentioned that you guys plan to add new cities, territories etc. Maybe make the cities and their areas (high society houses, slums, markets and all other) be describe with stats. When the area would be highlighted, there would be a small window in the corner of the screen with visualization of how this area is manage. The stats could be:
lawfulness (is the are safe or is crime on every corner),
wealth (how much you can earn in here),
military (does the city guard patrol the area and take action in here or not),
society level (low – the lowest standards, medium – the girls and the MC should generally know how to behave; high – girls and MC HAVE to know how to act and behave when blending with the high society people),
depravation (how much will the girls have to do – from holding hands to getting fucked by a hoarse and being watched by dozens pervs).
The general idea is that this fixed (or not) statistic would be displaying what kind of business should be run in the place and what kind of girls would earn the most money. If the society would be high, a lvl 1 girl wouldn’t fit in there and customers never want to see her in their surroundings; on the other hand high lvl girls and with certain traits would blend perfectly. This division would justify why free girls would want to work for MC (he can get them to the high paying customers so they can make more money than working on their own).
