I mean, i can't blame them, while mother/son, aunt/nephew, brother/sister have become mainstream enough to be one of the top fetishes both in the west and in japan, father/daughter remained a niche fetish along with several father/daughter games getting abandoned for both playing as the father or the daughter but the overwhelming majority being about the father as the MC due how few are about playing as the daughter
Also demanding for a protagonist to be changed has always been a thing here, the mother/son and brother/sister are quite vocal, this is the first time i've found someone trying to push for playing as the father instead of having the father "disappear" to play as the step-som
For most people sex is not a two way thing, because someone is fine with sleeping around as much as possible as a dude, they don't like the inverse
There's also being more comfortable self-inserting as a dude specially on the cases on FeMC games when the author/dev makes it explicitly clear that ("You") are the one getting fucked
Yes, it might supriose some, but people are selfish and hardly care about other perspectives
That along FeMC usually being a turbo-sluts from the get-go while also claiming that FeMC is not a turbo-sluts and FeMC games where you have to lose to get to the sex scenes.
