A visual novel is an interactive fiction game, usually in the form of a digital novel, in which the player takes on the role of the protagonist and makes choices that affect the story. They are often compared to choose-your-own-adventure books, but with graphics, animation, and sometimes music and sound effects. The term "visual novel" is used to describe a wide variety of games, including dating sims, eroge (hentai games), and story-driven games with very little gameplay.
