I think you should limit the maximum bet size whilst also limiting how many times you can bet and how much you can win, because Queen of Hearts is not really in a rich area, so to speak, so it doesn’t really make sense that the establishment has that much money to just give to random people winning bets while still making a profit. It’s been a while since I have played a game so forgive me if I’m wrong, but in other games like The Witcher series, it really depends on what part of area the pub is, for how much you can win, and it makes perfect sense logically and also prevents players from exploiting bets. I’m still on CH2, so I don’t know if there is a rich area in the game with a pub yet, but if there is, limit higher bets for only there.
I did check every other girl and filled their profiles completely like you said, still the same thing.
