I'll start off by saying that I have a lot of respect for Five Against One. The developer has actually previously finished a game, which is a tremendous achievement, whether or not you like the game, the art, or anything else.
That being said, I like this game. There is a nice selection of fetishes, but I wasn't entirely happy with the choices I was presented at the daughter's party, so I created a mod for my choices in the play-through. It took a lot longer than I was planning because the dialogue is, quite frankly, borderline gibberish in places. I expect the Five Against One is (single person or group) is not/are not English native language speakers. So I corrected a lot of the grammatical and spelling errors in the dialogue. It's not perfect, but it's a lot better than it was. I also added a walkthrough to highlight the outcome of choices you make, not that the game really needs a walkthrough.
The changes I made for daughter's party allow you to stop the daughter from porking Lucas, and still have a relationship with her. It basically hard-codes incest on. I also changed the dialogue with Courtney when she catches you with daughter to confess the incestuous relationship, since it doesn't change anything.
I want to emphasize that I did the mod for ME, if it doesn't suit you or you don't like it, don't use it. The mod is attached. Installation is the normal story, extract the files into your game subfolder, overwrite where prompted. Use at your own risk. I take no responsibility for it screwing up your game or blowing up downtown Dallas.
