Most of the games here aren’t doing this, but it comes up in a few of them and in a lot of other Kink Games or outright Porn Games I have tried: sex/kink content exclusively as an obstacle or failure state. Why?
It makes thematic sense for vore and similar, and there’s a lot of kink tied up in power exchange, fear, helplessness, and force. But it comes up more frequently than that, and even when it’s “thematic” it still feels disappointing? Like, I’d rather play a game that wants me to engage with this content rather than one that tells me I’m doing it wrong if I do.
It’s hard to integrate sexuality into game design! But I feel like presenting it as an obstacle, without careful writing around it and further expressions of kink integrated into the game, borrows a lot from the intellectual tradition of “sex is a bad thing that bad people do and you are bad if you do a sex” and it gives me this weird contradictory sense that a game going out of its way to present itself in a sexual way is, nevertheless, embracing Puritan sex-negativity and not in any kind of fun way, just in an uncomfortable and unexamined way.
I think Mark Rosewater has it right in his oft-repeated point that games need to be designed to point players towards the fun thing and creating tension around “do the fun thing or do the right thing” usually feels bad. I think there is a lot of room to play with denial/avoidance themes in kink, but it takes careful attention to theming and presentation to make it not come off as the other thing.
