Yeah, I hate how incest gets bandied about everywhere to the extent you can't take the tag at face value. Honestly, I don't really believe there's a subset of people who like adopted/step-sibling "incest" as opposed to the blood related, considering to my mind the entire appeal of the fetish is its taboo nature.IMO it makes creating and applying said patch irrelevant and a moot point as the origins of the siblings are already a part of the developing storyline and one that is impossible to change. Then again, there are some who consider adopted & step-siblings the same as if they actually shared a blood relation... me, not so much.
Without the blood related it's just regular sex.
On that note, what's the incest like in this game? Does it bring anything to the table or could you remove the incest and nothing fundamentally would change in the character relationships?
