ai is enabling people to make smut games. ntr is popular. so the answer to your question is: a lot.
the funny thing is, that ntr "haters" go out of their way to search those games and give them even more popularity.
i see a lot more incest games and incest is a far more extreme fetish. ntr is vanilla. cheating is a standard porn plot. bored housewive doing the poolboy. a classic. but then again, doing your "step" mom and thereby cucking your father is also quite popular.
you got it backwards. ntr requires more plot than non-ntr. you need one more character for cheating to occur.
for real ntr you need to create the humiliation fetish. if this is missing, you might have such netorase as here. or things that are not actually ntr, but called so by people hating ntr and that other stuff, so they call that other stuff by the worst term they know, which is ntr.
but plot complexity is not the deciding factor. sloppy developers create for a perceived audience. creating for mainstream smut audience means competing with mainstream smut. and ai is not good for that. creating for nieche smut audience means an audience that has less games to chose from and even mediocre ai games can shine there.
No? the genre doesn't matter,this is not some competition,it's all different type of porn at the end of the day,you can make slop for any genre, there are some high quality vanilla,but I also saw some of very,very sloppy ones that makes these ntr look like AAA games.
vanilla is the default genre for porn thus of course it has many high quality ones and the majority of good ones but at the same time it result in many,many very sloppy ones which are also the majority of the sloppy ones which is normal due to their sheer number
