I dont know if they will but in any case, like most probably every player here, I hope so.
I presently have 60 girls. Probably fifty of them are full affection and I have a 100K/hour wage (in average huh)
with girls. Then Ankyo 5 stars (who is the 15th in my harem) will probably cost me something like 15 k affection + 14M.
Ok it's a porn game, but it's not a reason for asking for obscene amounts of cash to players. So as far I'm concerned I just refuse to up
her and the next ones to 5 stars and I will up the other ones to 3 stars during this time (which is not so hard for a veteran but I don't even think what a new player think of a 900K for a 3 stars).

Here the problem is that even if you accept to pay the cost, the next 5 stars will cost you even more until something like 150M and 1 month gathering 24/7 ?
So actually the more you are veteran (being high level)/have girls, the more the developpers thank you by make you pay more if you want them at their maximum level.
However, getting more and more girls isn't the goal of this game ? so maybe have some cap by level could be a great idea (same for the cost of pachinko)
I mean if tomorrow some people starts scripting using automation software based on image recognition in order to gather the money they will get an instant ban. In an other hand there is more than 100 girls available in the game , ankyo is just the 5th one, and she will cost you at least 10M. So I will let everybody here do the maths on how many times they need to get a 10M investment being worth it according to their play time and their money income.

If you agreed let a little comment on #saynotogolddiggers
