But you'd run into that type of problem for some people anyway. Like yea most people are going to play the full harem, incest or not, but for those who aren't, who for whatever reason turned down certain girls, are going to get shorter updates sooner or later than those who are with everyone.
Regardless, I was simply pointing out an option. And you're right, with that many girls available, that is a huge number of combinations.
I think the important thing though, would be to have good in-universe reasons for the patched version why certain threesomes etc don't happen if they feel like they naturally would normally.
Like, Martha + Meemaw happening makes sense, they've always gotten along well, Norah + Meemaw makes sense not to happen given the antagonistic history between them. It'd take a lot of work for them to get to the point of being close enough for a threesome together.
Samantha + Simone on the other hand, I could see very easily and naturally, having threesomes with MC together. Their personalities would work well for it I think. So there needs to be a reason why it doesn't happen. And the reason (in-universe) can't be incest because for those of us who play patched, it'd make no sense. They're ok with MC being in a relationship with everyone in his family, but they can't be ok with themselves having a threesome together. It's messy logic.
