I don't know man this one feels like a god damn Gordian Knot of interweaving of complex shit. That I am to ignorant and lazy to give any real answer to heres my best shot.
My gut feeling feels its origin goes way back to the bad ole slavery days with the young and "curious" owner's daughter...
Lately its been games but definitely not anime or hentai due to the censorship and aggressive looping. Real actors would be next but most of the actresses I followed burnt out and left the industry, and the fakeness and limited scenarios started to bore me.
Bilateral spider girls because I am terrified of spiders and I am deeply mentally ill. Normal cat girls and shit don't work for me because they don't commit to either side and I keep thinking about whether their ears are decorative or functional and if only decorative do they have a second...
The moment it can do decent animation which is a good ways away 5-7 years I might show interest in it. The images produced by AI alone I kinda hate seeing in games because consistency between images is kinda important.
I never got into character customization. I do my usual skin tone and make em bald. But character creators have gotten worse in a lot a games cause they want more realism so they dial down a lot of the options and make everyone plainer.
The story and mechanics were at like 95% of the way there. Dev just needed to clean up final act and end it. Def worth playing because the remainder of the story was most likely wrap up.
Stories are dog shit but I love seeing a character from a show/game/movie I watch/play in a porn game scenario. I prefer for them to be in their world and setting tho,
