So for me, it makes no sense, as much as I really like is, I really dislike when they get a game that is clearly not incest, and make a mod for it adding especially when it's mother-son/father-daughter, you can tell how shit the conversations gets
The step crap is worse in my opinion not only because there are people that act as if a step anything is the same as someone related by blood (even talking with disgust to a relationship), but also because they lose most of the point of incest, especially when the steps-"insert relationship here" have known each other for a very small amount of time which is how it is most of the time (and my biggest problem with it), If at least they made something like parents marrying when the kids where 1, and they grew up doggeder, or the mother/father got married when the kid is a baby you can even make an argument, but noooooooooooo
