Well, yes, I already explained a few times now, doing a patch to keep the old setting would force me in time to have two different games as the story would evolved differently, if Marc was still her son and if Marc was only Anthony's son, it would be a nightmare and would make me lose a lot of time. This is why I choose to cut short and fully rewrite the family setting and keep a consistant story and not lose time I could put into advancing the story.I do understand your points and agree with you. The patch would have a major impact on future branching paths for Marc and his sister.
The biggest problem would be creating extra renders for different branching paths, which is time consuming and might end in an incoherent story. Form a technical point there isn't much work to do since many other games have outsourced their incest, loli and bestiallity content to lewdpatcher already.
Since Zorlun agrees with your post, then I assume, that he isn't willing to work with the community and a modder to reinstate the unrated dialogues for Marc & Co. With that, there is no reason to continue this topic any further.
Take care.
So I know it's a disappointment, but I won't go working on a patch with somebody when I chose a road to avoid that choice in the first place. But after that if people want to make a mod to put back old dialogues, well they are free to do so, as any other modders shared their work on the game here, like the gallery, the walkthrough, etc... (I can also share old version of the game if people want the old dialogues.)
