I don't believe that there are centralized variables for those things even in the dev version. It's prolly simpler to give yourself a lot of cash, find script.rpy file, there should be:
label after_load:
# Some code
at the end of it, add:
label after_load:
$ hero.gold = 1000000
to it and load one of your saves. Make sure to delete that or it will be annoying having your gold reset all the time, that will mess up your finances as well (a bit). You can use hero.add_money(100000, "Cheating") if you want finances to remain intact.
This was an interesting experiment. The money lasted quite a while but unless the girl had a good enough level to create an income that sustained the taxes and expenses, it was just a money drain.
Two days ago I downloaded renpy and tried to recreate the .exe from the files that come with it, but it gave me a couple of errors where there probably shouldn't be any. I wonder if they are python features that renpy didn't recognize.
I took a good look through the code, and while I don't know python, I know enough basics to follow the major intent. I was going to change the jobs section to increase all girl income 10% and then recompile. The errors I mentioned above stopped me for now.
My current opinion is that the game really needs 3 difficulty levels, the current one is HARD, 10% more income is NORMAL, ,and 20% more is EASY. Changing the tax level would have similar results, but I don't think it would go as far as I am suggesting. Still, it is probably the easier choice for a quick fix.
I think the rank system was a correct choice but not implemented correctly. If each brothel gives a rank limit one higher than the previous (2, 3, 4, 5, etc.), then the fourth building with a max girl rank of 5 should have a target client and girl rank of 4, and no client will enter that is outside a +/- 2 range (rank 2 to 6). That way most of the girls can be in the right range for the clients and rep loss goes way down along with most of the rejections. Part of the selection could include a rank test first so a client does not pick an unsuitable girl.
By this plan, the 2 room house would never have a client above rank 3, and the fourth house would have clients of rank 2 to 6, with most of the girls being rank 4. Any girls rank 3 or 5 can have a problem with some clients being too high or low for them. This could be tightened even more so no conflicts occur, but having this much range will maintain some of the color of occasional rejections.
The clients should have a rank level based on their type, and maybe more descriptions should be made to maintain variety.
1=beggar, 2=peasant, 3=laborer, 4=staff, clerk, 5=merchant, businessman, 6=well to do, politician, 7=celebrity, 8=nobility, 9=royalty
... at least this is the idea, it needs about 9 or 10 steps, and some ranks could use two descriptors if possible to give good variety. You don't really need to sort out the pics unless you feel a driving desire to make work.
In general I feel guards don't get exp fast enough, they are the slowest by far, and they also get Con the slowest by far which is wrong (I'm thinking weights don't work for them). All girls should be evaluated by shift, and a shift should be about as tiring for each (slightly more for dancers, less for serving girls and guards), though guards currently seem to have more time for resting. Currently dancers get worn out way too fast and servers tire too fast also. From what I've seen discussed you seem to be moving in this direction.
Guards only generate revenue when they stop a fight and the client pays (they are not supposed to make money for the business). Servers make bar revenue and tips while keeping clients longer to spend more money. Dancers make tips and increase the revenue of the whores instead of making money directly (maybe a cover charge) while also keeping clients around longer to spend more. Whores rake in the main revenue augmented by clients who are drunk and or super horny, though a good bar can bring in a whole lot of money in a night also, that is why they are paired with strip clubs.
Personally I think maybe whores should be dancers, not separate roles, and clients take them to their room after a rousing dance, all part of the same shift.
Enough for now, the game has been interesting and I see it getting better (slowly).
