In Strive for Power, the characters' family tree was traceable and also influenced the text during the interactions. (e.g. I had a female character with a brother and four children and when drinking tea it also said: "Your brother ..." / "Your son ..." / "Your daughter ...")
I would like to suggest that this be reintroduced. Maybe expanded with a random generator that takes into account family, gender and age, creating a family relationship between the house residents. (In the sense that, for example, an arachna is not specified as the mother or sister of a nereid. Except, of course, if you also incorporate adoptive parents and adoptive siblings.)
P.s. it may of course be that parts of it is already there and I just didn't realize it, then I would like to apologize for it.
P.s.s. Even if I have no idea about programming - I despair when creating a macro for a random generator in Excel - I also know that the one I proposed is probably a lot of work, but at least I wanted to suggest this because it was in the first game - from my point of view - a nice detail. I also like the idea that you can run the whole business with only the family.
