Readers of visual novelsGood developers try to please the reader. But even with this position, they do not always guess what the reader needs. The developer is one, there are many readers and they have many opinions. I'm collecting some of them here.

  • If you want to add something beside the story, then consider character profiles. It's nice to have a card or page showing the informations about the characters in the story. Like name, age, birthplace, favorite food, relation with the main protagonist and/or the other characters. Also a picture or picture gallery is nice. The gallery could consist of pictures which have to be unlocked during the story. Most people love collecting stuff in games, so if they can unlock photos of their favorite characters most will try to get them all. Source.
  • I used to work in an eroge company, this one time we did a survey and found out most players actually wanted better writing, world building, characters, it was a surprise for all of us but judging previous top games like fate or dies irae it makes a lot of sense, at least for this specific market a lot of people only want erotic scenes when and were they make sense. Source.

  • It (sex) is also going really fast. Some of us like stories to go a little slower.
    The good parts is that the women all have a different look and they are all pretty in their own way. I like having a few older women in the story.
  • I get the desire to cater to those who pay, but a story built-by-committee usually ends up as disjointed and incoherent as you try to appease too many different people with varied tastes. Tell the story that you want to tell, with the content you want to have. Patrons who like what you're producing will come.
  • If I'm interested in games is because it follows the mc & the girls, not to see every other character fucking someone else.
  • There is not a real story, just a collection of disjointed sex scenes without any sense. Characters doesn´t behave as real people at all.
  • My advice for the dev: knowing how to make amazing 3D models doesn´t mean knowing to create a game. You need to know how to write a story a create credible characters that talk and behave as people. 
  • I would like to see are more sexshots and more angles so as a hint just use the same pose and rotate the came around for diffrent angles and render that out so you get more shots out of one pose that still saves time for more content and makes sex scenes longer and diffrent people prefer diffrent body parts so dont focus too much on ass just gives every body part their angle shot if possible.
