There were no specific changes to the logic for accepting a job or the wanted salary with this version (or any recent one for that matter). It's probably just a bad luck with RNG and getting several hard to hire girls in a row.
I have no plans to expands on that scale from the current 0-12. I'm not sure what we get from higher levels or when they would come into play. You are correct with the not much value going below 2 for standard clothing. Several girls have those and you rarely see them because even when they are legal to be worn, now they are competing with stripper dresses so they rarely get used. That said, if someone suggests a good case use for it, then I'd be open to it.
Fertility (as most attributes) goes -100 to 100. So 0 is actually average fertility. (It's confusing that a few attributes go 0-100 and I wish I hadn't done that cause it bites me in the ass all the time when I forget which are which).
You can turn off pregnancies by the user_config.dat entry:
base_pregnancy float 0
if you prefer no one to get pregnant. This doesn't turn off all the birth control stuff, and it should. That's will be fixed on the next version.
I'm not sure I follow all of that... but:
* About the economic model: it turned out to be much harder than I anticipated and I never want that to be the focus of the game. If you want to play to optimize your cash flow go ahead, I'm not going to tell anyone what to enjoy. But I'm not interested in building a business simulator so this game will always fall short in that area. Even if I spend all my time on it, it will likely still not be good enough. At the end the strip club is an excuse to put the MC in a situation where he or she can interact with a bunch of other characters in a sexy environment.
* You got 20 girls pregnant in one year? That's impressive. I should have made the achievement for more than 3 in a year then!
* Yes, negative opinions wear out too. Almost all opinions trend towards 0, each opinion has it's own rate of decay. (The ones that don't are things like "family" or "is tall" that don't change.
You know that's a great idea. Not sure why I didn't think of it. Will add it to the list. (You do have various options to replace her birth control pills with fake ones though).
In general, when the opinions are opposite one is enough. So if they hate mono, they will automatically love poly. If you do try to convince someone that loves poly to hate mono, that should always work and it should tell you that she already does.
Never tried waiting to open until after the kitchen and sitting area are built to open the club. I think that would be worse. Once you open, you can start building up your fame which is what drivers customers. When not open your fame won't grow so by the time you do open in that case you will be getting very few customers and will be losing a lot of money on all the salaries you be paying.
Your home is not an option cause you have no home
. It probably should be but at one point I thought it made things too easy. That said if it your girlfriend, you suggesting to go to her home should be an option. I will look into that.
And I do like that way to turn off pregnancies. Maybe I'll do that.
