AI art can create complex images with low time investment, but you have only few control over what is shown.
With DAZ, Blender and Honey Select, you may have simpler looking characters with low time investment, but you have more control over what is shown and can make it more consistent from image to image.
For catching people you need interesting images that look not to weird but stand out of the masses of images, people are used to see. Dependend on how much time you invest in your work or how much luck you have, your game might succeed in this or not.
But you need also to consider, that people try just to find interesting content with minimum effort. If too many people use AI-Art in a lazy way to just create uninteresting content, it may be/get a symbol for substandard VNs like it is also often seen for VNs with Real Images or Honey Select images. So people may just exclude AI-Art-Games in general without even looking on the concrete game, that might have decent graphics.
Another thing is keeping people. For this you need in my opinion:
- consistent images, that convey your story (especially the images should indicate emotions and show change of emotions) => inconsistencies distract too much from the story as they divert focus (similarly to spelling, grammatical and logical errors in a text)
- a compelling story
- decent looking models
- decent writing skills
The importance of the aspects is in falling order, so image consistency and conveying of feelings is for me much more important than decent models. And there you will have the big problem with AI-Art.
I like literotica and noticed, that I can basically fap to a written story, but it must be very very well written. Images would then be just a surplus. But those stories were actually only very few, much less than VNs I saw. I think, it is much easier to create a good VN than a well written story (if you are an amateur and don't have the necessary skills).
I actually often install games with decent looking images just to deinstall them soon, because there is no conveyance of story or emotion. My most recent game in this regard was:
https://f95zone.to/threads/sex-lens-a-porn-story-final-romantic-room.180627/
It's not AI, but the same principle,.The images look quite good and there is lots of sex already in the beginning, but there was basically no interesting visual-told-story, even before I came to an game-breaking bug. So it was just a game to delete and forget.
A positive example:
https://f95zone.to/threads/the-headmaster-mykocks-manor-altos-and-herdone.23470/
The images are "only" Playhome (comparative to Honey Select) but the whole visual-story-telling there is so great, that the game catched me for a very long time.
