I disagree. The Ranch / Farm plot has a full right to life, even taking into account the rules of Patreon. Pet play on patreon is allowed, Zoophilia seems to be not (although, as some players write, this prohibition does not interfere with the sale of these games).
A few pages ago, one of the users wrote that a certain game consisting of bestiality is selling well, and on their patreon page, the developers describe the sexual interactions of characters "not as bestiality, but as the sex of people dressed in animal costumes". Sounds ridiculous, but it seems to work.
Bureaucracy (and patreon is no exception) can be quite clumsy and if you know how to get around it and not break the basic rules (incest and pedophilia), then it is quite possible to successfully sell your games.
But back to the Ranch.
For a start, this plot can be limited to Pet Play and BDSM workouts for Monica. The upbringing of slaves is in many games (this is not prohibited on patreon), which means that the same can be implemented in FB. Monica could begin to be trained to be a submissive slave and severely punished for any wrongdoing. And believe me, the content with BDSM fetishes and petplay will be enough for a large number of updates. After all, in the main FB game, Monica gradually corrupts, which means that on the Rancho/Farm there is no point in immediately putting her under a pig or horse. (sorry, Lara Croft)
I can give a vivid example - the Insight of You game ---> https://f95zone.to/threads/insight-of-you-v0-8a-adventanyx.45441/ which, in fact, is a rather tough training for one rich, arrogant and influential lady (just like Monica), in the process of which a business woman is made dependent on orgasms, sperm, cocks, humiliation, spanking, pissing and turns into an absolutely sex-obsessed sex slave. And I see no reason why the DM couldn't do the same to Monica at the Ranch.
So, as they say in my country - "there would be a desire." And if the DM has such a desire, then it will be quite possible to realize a significant part of what is planned at the Ranch / Farm (I am sure of this).
