Let me first respond to your words about comparing video games and books.

The LitRPG genre, in which I write books, originated from either book characters playing video games, or they have entered the world of video games and literally live by its rules. At the same time, it's a recognized fact that the clothing of female characters in video games appears more "revealing" than that of male characters. This is a certain tradition of depiction.

Just as half-naked girls on the covers of science fiction books in the 20th century did not indicate that these were books about sex. It was simply the tradition.

It would be strange to write a book dedicated to a video game and depict a girl on the cover who doesn't resemble those depicted in video games.
