Regarding "interactive audiobook"

[Hanon Ondricek]

What exactly do the different story types do? (In the dialogue when creating a new game.)

RPG favors the picture window and the side menu, interactive fiction favors the text window. Visual Novel makes the main picture the background and slowly reveals text. CYOA seems to not show a picture unless one is called and then dismisses it.

What exactly does "interactive audiobook" do, and how should it be used?
