Not sure if we really want to see a mother-son conceived, hunchbacked, clubfooted, giant-dwarf baby with trisomy 18 and 21 at the same time?
I mean, it is one thing to implement incest per se because of the HUGE societal taboo. The other thing is to actually think about having a baby with close family members.
Also Meredith is way past the age where she could safely have a healthy baby. If she's even still fertile at all.
First of all, the incest kink has got nothing to do with real life. Just because people enjoy it in erotic games, most likely because of the taboo, it doesn't mean that most people really want to bang their close relatives like moms and sisters.
Something similiar is a matter of fact for pregnancy content. Yes, incest in real life has got severe negative consequences for the offspring. But
this is a game, not reality. People will enjoy the mc impregnating his mom, sis and the aunts and a lot of people will also enjoy watching them have sex with the mc, while having pregnant bellies and all natural
swollen tits.
Of course people don't want to be burdened in a game with all those sleepless nights, because the newborn is crying, etc. So the dev got it completely right:
impregnating and pregnant sex will be in the game at some point, but not taking care of the child and also clearly not any birth complications or disabilities at birth, because of the incest.
I don't remember Meredith's age, but I guess she's in her early 40ies? She can still give birth to at least one more child, before the menopause. A lot of women in the West nowadays get pregnant, when they're in their 40ies, after they've had a career. It's actually pretty frequent that Western women get their first child quite late. In the early 40ies it's usually still very much possible and likely to give birth in a natural way to a healthy child and also even later due to modern medical care and reproduction science.
And btw ancient Greeks didn't "invent" anal sex.
