I know many do not understand how much work it is in making a game, just for some "few" scenes.
Those scenes got much work put into them when you pose the characters to the desired placement you want, and making them
look good when doing that pose, and to make them look interactive towards the other characters in that scene. Yes, there are pre-made poses. But often they even have to be adjusted to fit the character. It can take a long time just to get these things right.
Then you have dialogues. Try to make a scene with these things made well and see how long time it takes. (making a realistic conversation between 2-3 ppl.. when you at the same time need to shorten it down so there are not too many conversations that ppl end up losing interest) I promise you will get an "aha" experience. So I can really understand why it takes so long for a game with so many images for each update to get released. But I do agree, with this progress. No, not good.
This will take to many years to get an erotic scene with some naughty content that ppl are often after.
Ppl subscribe to get naughty stuff. If they want a tease and no action you can buy most games now' a day that is rated 16+ and see nudity and teasing scenes. But again, those games are all animated, so they will score higher on that part.
I'm not saying that I've made a great game myself, but I at least put in naughty stuff so ppl get what they are expected.
And please, not all are actually trying to milk ppl for money. I know several creators that do it because they love to make these kinda things, of course, they are happy when they get supported. (just like me.. because the computer I pay for monthly are not free)
Lust has made a really good game when it comes to the story part, the dialogues I read fully and are loving every second of it.
But I must admit things heat up to slow. If he only at least could put in more nudity at least, I think many here would be happier
