Gameplay
Visual novels are distinguished from other game types by their extremely minimal gameplay. Typically the majority of player interaction is limited to clicking to keep the text, graphics and sound moving (most recent games offer 'play' or 'fast-forward' toggles that make even this unnecessary).
Most visual novels have multiple storylines and many endings; the gameplay mechanic in these cases typically consists of intermittent multiple-choice decision points, where the player selects a direction in which to take the game. This style of gameplay has been compared to the Choose Your Own Adventure books. Most, however, strive for a higher level of plot and character depth than the aforementioned series of interactive children's books. These can be more closely compared to story-driven interactive fiction. While the plots and storytelling of mainstream video games is often criticized, many fans of visual novels hold them up as exceptions and identify this as a strong point of the genre.
Some visual novels do not limit themselves into merely interactive fictions, but also incorporate other elements into them. An example of this is Symphonic Rain, where the player is required to play a musical instrument of some sort, and attain a good score in order to advance. Usually such an element is related as a plot device in the game.
Some shorter works do not contain any decision points at all. Most examples of this sort are fan-created. Fan-created novel games are reasonably popular; there are a number of free game engines and construction kits aimed at making them easy to construct, most notably NScripter, KiriKiri and Ren'Py.
Many visual novels use voice actors to provide voices for the characters in the game. Often, the protagonist is left unvoiced, even when the rest of the characters are fully voiced. This is to aid the player in identifying with the protagonist and to avoid having to record large amounts of dialogue, as the main character typically has the most speaking lines due to the branching nature of visual novels.
