Especially since mindbreaking Whitney is likely the single most vile thing you're allowed to do in the entire game, and in my book one of the best-written events in CoC because it's the only time that taking the corrupt route really makes you feel like an utter monster. It's admittedly been months since I last played CoC, and that was for a speedrun, but to my recollection the farm corruption hits the right notes to make the Champion despicable in a way that makes the writing of things like Amily and Jojo corruption look incredibly shallow by comparison. It's especially noteworthy for being a late addition when late CoC had gone fully into being Super Waifu Simulator, making the quality of the event stand out all the more.
I'm glad you liked it, I put a lot into it. And that was what I was aiming for, yes - an event that made it clear your character was evil, not just a slave to their lust, in a way that was hopefully still arousing if you were into that kind of thing. Whitney's farm was supposed to serve as a moral event horizon for corrupt characters, the moment they might begin to think they could probably do the whole demon tyrant thing a lot better than Lethice was. A lot of players expressed regret that there wasn't any way to romance her after I'd given her enough talk scenes for her to be an adult with thoughts, feelings and flaws that you were doing it to. I wasn't all that bothered about Fen's thing about not being able to pure fugg her, but I do wish I'd provided options to invest in her farm in a non-corrupt fashion. Or done the whole pure Owca thing. There were never enough opportunities in CoC for the player to be nice, mostly because that wasn't as fun to write.
You sure talk about morality a lot for a game most of the players pop open, check the newest scenes/their favorites, fap, then clsoe and (sometimes) save. CoC (and TiTS) are hardly masterworks of storytelling and deep engaging characters.
Writing and games are what you make them. I mean, I agree you shouldn't try and reproduce Tennyson when writing smut, because it's wasted effort and will probably detract from the main aim. But it's not one-way. I use CoC and TiTS to try and improve myself as a writer, and events like the farm corruption thing - where you try and convey a mood, something about a character, and about the player character themselves, within fairly limited constraints - are a really good opportunity to do it.
The other part of this is, if you set a certain standard in a game, then that is what your audience will come to expect. If you think about what you're doing, you edit it thoroughly and give it to competent coders and disseminators, then you will find a large, discerning audience and hopefully inspire other good writers to join you. You push out absolute garbage like the behemoth and scraps of other people's projects? I'll let you finish that thought.
