They are only the family that you can give them their name... all the other characters will have a default name... I am also looking at putting the default name to the family, but the truth is that I would not like to do it because I want everyone to become attached to the family in their own way.
And in the end give them that happiness or that guilt because they have named the characters that name.
Well, I don't have any game save, so probably the name will be asdf ñlkj for the MC and 1, 2 and 3 for the wife, the daughter and stepdaughter. asdf is a name that I use a lot when I'm forced to name a MC. I don't usually have to name girls, so numbering them seems like a great option. Although if I have another game open when I play again, I might use whatever name the MC has in that game, and use the first 3 female names that appear in it as names for the mother, daughter, and stepdaughter. We'll see when it happens.
It's nothing personal, it's that I prefer to have pre-established names since I never know what name to put (no, I have never used my name for the MC of any game, and I will never do it)
And from the stepdaughter I plan to do everything except kick her out of the house, as I said before, she is the key for everything to start
Ok, as long as there aren't any forced sex scenes with her. I can accept the MC making her life miserable, and even torturing or blackmailing her, as long as we can avoid all her sex scenes.
Like the example you gave, if I plan for there to be decision events that have their consequences, both in the course of the plot and in the ending.
In my case I will not prostitute the LIs. However, if it has negative consequences in the course of the plot, there is a 100% chance that I will not continue the game after it. And if it's going to have negative consequences for the ending, I'd rather know because I'd rather see no ending than see a bad ending.
