The biggest issue i have is that in the current builds you are locked out of certain paths like having to choose whether you pursue Mia or Mia's mother. Those locks should not exist and you should be able to pursue them both and then have a branch activate once you have them that opens up a group option (threesome with Mia and her mom or a foursome bondage scenario with the Nun).
I personally think those choices are great and enable much better writing. Quite a few patreons don't like them and because of that DC wanted to introduce fewer of them, but in Eve's update we kind of see where this is leading. Right now you basically can't have a nice Grace story/ending because you basically always have to cheat on Eve. I'd much have preferred a choice here at some point, so you can actually explore both possibilities.
Especially for Mia her choice really makes a lot of sense, given how she seems to feel about her family and Helen.
That said, DC hinted recently that especially Judith's story may get a choice between either her or the Latinas, which sounds right to me.
I think, that good writing benefits the game much more, than some additional three- of foursomes ever could. I mean, sure, you can always imagine a scenario where every constellation is possible, but in most cases that simply leads to atrocious writing, like we see it in so many other games. It's never a good idea to imagine a scene you want, to then try to bend the existing plot, so it may fit in.
After all, there are more than enough "in character" possibilities for stuff to happen, like Mia and Ms. Ross, Jenny and Jane, Diane and Veronica, Mrs. Johnson and Anna, etc.
