the idea of the pigman breeding farm is really good, in fact, I think there are some monsters that should return and have more relations with Claire, some examples:
1 - Pigmen: The prologue shows two encounters in which the pigmen are able to somehow communicate with humans, one with Claire where a pigman helps her enter the prison in exchange for food and the other when a woman talks to the master pigman and she even encourages him to ''try'' to rape her and the master pigman gives up because she would be someone stronger than him. Claire should really have more encounters with the pigmen, especially the friendly ones, maybe they could work as '' employees '' at Claire's ranch in exchange for sex with her and the other women or simply more interactions with them in any other part of the game.
2 - That monster that resembles a facehugger: one of the best monsters in the game, Claire can have a good ending with them if her strength stat is high. These monsters, because their eggs are valuable, could easily return to Claire's ranch if she gets the good ending. Claire would carry a facehugger that over time (days or weeks in the game) would evolve into a larger one ( thus having option of having sex with facehugger or the big one ) and could produce eggs by having sex with Claire and the other women, so the ranch would have another source of income.
3 - Goblins: They appeared briefly and for me, they should return with force since this game focuses on monster breeding. They could return to some parts of the forest and if they capture Claire, she would be raped in the goblin den and give birth to new goblins and after a while Claire would have the opportunity to escape, so without needing a "game over", the player could play and rewatch these scenes in the game as much as they wanted.
