Maybe i can give some more insight on the use of AI in the game, i work on editing and the official walkthrough.
Storyboard:
The storyboard is done by Irphaeus and its very sexual and sometimes violent nature wont be able to be done by AI, at least by the models i know. Also the story is now well on its way into the last third and how would an AI finish that while making sense. So no use there.
Images:
Images are done by Irphaeus and now in addition by two part-timers, so there should be a speed up in image creation. To keep the spirit of the Honey Select engine AI won't be used in the middle of the games creation, especially again because of the sexual nature of the game. The only use of AI is to touch up some very few images, especially close ups, to look more "realistic". Maybe you can spot those in the later updates.
Music:
AI will probably be used in this field more heavily in the future, since not all free music is fitting and it's not an important part of the game.
Writing:
Feeding an AI with the storyboard could work, but then lots of the humor and sassiness would be lost. Which is in my opinion one of the biggest draws of the game. All of the text is written by a medical doctor in hsi free time, so all of his knowledge and 'foreign words" would be lost as well. I tried AI for editing but it just spat out nonsense most of the time, especiallybecause the writing is already embedded in the text code for the VN.
So music and some rare art is touched by AI, but all the other parts won't really work without a heavy time investment.
