Buckle up people, because it will take around two years to get any incestuous sex, if the dev’s money-smart. The end goal of this genre is the taboo sex; this is the same as the hero defeating antagonist, their henchmen, and returning to the ordinary world with the elixir to save their tribe, ending the story.
The game ‘The Twist’ is a perfect example of how if you are given incestuous sex over and over, it gets boring, as the novelty of this forbidden relationship wears off (of course they’re related: that’s the twist). The dev will long this out with a million pointless sub-characters (notice how so many games of this genre keep on adding characters for no other reason than to try to hide the fact THERE IS NO STORY), and hours of dribble that they think is meaningful dialogue, and a story that was probably put together on a crumpled envelope between the words: BILL OVERDUE.
Of course, a well-written story could have the most depraved orgies every single release, and it’d still be interesting, and you’d want more (regardless that only a handful of characters were in the story).
But that would require a skilled writer; the only thing game has going for it are its graphics and its chosen genre (like Midnight Paradise).
