Are you not aware that the Prometheus patch is still being produced, and is released every time there is a new upate? The fact that Patreon prohibits it hasn't stopped the Prometheus patch. Your argument is therefore invalid.
When you say that Zorlun has said multiple times that "it won't be in the AVN", I'm assuming that you mean sexual contact between Myriam and Katherine. If so, we've been over this before. The last time this argument raged in the thread, Zorlun posted to clarify. His statement at that time was that there will be a threesome scene between Myriam, Katherine, and William, but that he currently is not going to include sexual contact between Myriam and Katherine. However, he also stated that nothing is set in stone, and he will leave himself the option to change his mind. So, currently, no sexual contact between Myriam and Katherine is planned for the game, but there's still a chance he can change his mind.
Here is that post from Zorlun.
But the point of my post wasn't specifically about incest between Myriam and Katherine. It was about the fact that Zorlun can include anything in the game that he pleases, because of the Prometheus patch. And that point is clearly correct, because he is already including bestiality in that patch, which is just as prohibited by Patreon as incest.
Clearly, it is not. We are still discussing it.
