If you read the spoiler to the .03 changelog you'll see that Ain got aged up, if you do some digging you can even find a .02 or .01 pic of her during her intro if you wanna compare, so it's not unsurprising that there may be some incongruencies specifically with things established early on development, with that said I personally think her updated look is an improvement, particularly her face and I think some recent plot threads work better with the rework instead of the original particularly Zahra being concerned about Ain finding her place in the world and that talk with Ain in Zeta on the wall of the city courtyard.
Maybe it's just me, but if you pay attention to their expressions, it seems to me that both Igor, and Kat are both uncomfortable with most of the sharing scenes, particularly the one where you share Kat with Igor, so much so, I almost rolled it back out of reflex even though it wasn't on my main save. Maybe they have a complex about sharing and gangbangs due to their rejection of their own culture's sexual practices?
I'm going to have to go back over those scenes and see about Igor and Kateryna, as I'm vague on that and wondering if I actually missed that particular scene.
I do recall multiple conversations w/Ain and Zahra asking what she wants to do with her life: and there was a multiple choice option and another about either starting some other household or taking over her own (the latter caveated as Z knows full well A is very fixed on her father).
I think I briefly started playing in version 14, then restarted in earnest in 16 beta, so I'll have to go back and look. I did see the intro got reworked a bit. I also noticed that between 16 beta and 16 Alpha and Bravo they reworked some of the dialogue in the Lirah quest. I kind of liked some of the beta dialogue better, bur what they have now works. In fact the only issue I've seen is that the Lirah quest replays from all versions doesn't actually have the full dialogue but omits the fact that she's probably carrying your child when you see her again after the humiliation and it's her and Talia at the gate.
Ain is hot. Unquestionably. Especially when she does that "boo" scene when you go to visit her in her room, and the outcome of her being awake while you have some fun with her. Actually, yeah, just about everything with Ain is pretty hot.
That said Shani is pretty fucking smoking, too, and Zahra (especially in certain scenes) is the bomb, as well. Just a well put together family.
Shani end Zahra also have more attractive personalities, as well,imo, as Ain can get a little too full of herself. To be fair to Ain abt that, though, she's being pushed to be Zahra's replacement brood mare: specifically trained to pleasure her father and any guests, and pop out daddy's kids. There is so much pressure to do these things specifically that she doesn't even know what she means to her father outside of his being his willing, obedient, and available fucktoy... Got to say: that's got to do some SERIOUS psychological damage, and it definitely points to the fact that there are reasons that most societies don't do this sort of thing.
That said, Ain is still super fuckin' hot.
