Instead of just using a hand-waivey reason that magically ensures no pregnancy can occur unless it's the MC?There used to be like 3 scenes of whoring out your girls, but it was all purged from the game.
Dev's friend explained to him that since the MC is explicitly trying to resurrect his clan, so it does not make sense for him to risk the girl's getting knocked up by other men. And dev realized that "hey, that makes sense".
So he deleted all such scenes from the game.
Super lame. Dev could've used any number of reasonable solutions but instead just went for the nuclear option
