I'll quote you both together, as it's basically the same reply from me: if the consequences are not yet published, then the choices have no discernable outcome and the experience is kinetic. I don't enjoy a game by looking through the code. Okay, I'll admit, I never explored being an asshole to Katie, so there's something else other than the prison that was not kinetic or cosmetic. I consider cosmetic choices to be choices that don't change the plot in any meaningful way, they exist purely to allow players to either skip lewd scenes for kinks they don't like, characters they don't like or provide an illusion of choice (ie in an RPG you might be offered the choice to save a person or let them fall, but the plot requires them to fall, so your attempt is in vain, you have the roleplay, and maybe one dialgogue in the endgame changes colour to reflect you tried but not enough).
What I mean but the plot basically reconverging is the same as semi non-linear RPGS - they have a main plot threaded through, you make choices on the way, but those choices don't alter the fixed point's basic essence, maybe just flavour the dialogue slightly. It's a way to allow choice and flavour the end game, while still having basically the same antagonist. It's super rare for example to have a game where you can completely side with the antagonist and decide the world isn't worth saving.
My belief is WiaB will follow a similar path - the player will have choices, but there is a canon ending to match SG. Maybe if Leia gets pregnant, she'll always have an abortion in the end game. Or maybe if she doesn't get pregnant, she'll find someone else to be a sperm donor. End result in either case is that if Leia being pregnant is required for a character is SG, it will happen, if Leia pregnant isn't canon, regardless of Willi's choices, she'll make her own. That's the easiest way to get around plot inconsistencies between the two.
From what we know from SG, Willi was pretty active if the the whole team was taking back shots from him, so harem or not, there is expected to be a fair bit of promiscuity.
And as I say, I'm talling about playing the WiaB game(s) in (their) current form, not about the code and plans. Having completely different paths that lead to different outcomes is just not going to happen - ZPR will become a thing, so common ground is required between certain WiaB elements regardless of choice now.
This is just my opinion, Ocean doesn't listen to me at all, so feel free to disagree with me loudly, it's not a hill I really care to die on.
