Graphics, music, plot, atmosphere, realism, immersion, and the such are not gameplay. They can help present information, making more choices interesting/meaningful (since un-informed decisions are often not interesting). They can certainly help the user experience, but that still does not make them gameplay. Gameplay is that which sets games apart from just movies, music and other art.
I agree with this. Gameplay is about the play (that is why it is called gameplay). Graphics, sound, etc give a context, but are not gameplay. They can increase the experience of the gameplay.
I think this is where the confusion about gameplay stems form. Through a process of elimination we can define gameplay.
What is ti that games have that other media or play dosen't. Don't include computergames, but also include boardgames, sports, and other forms of play.
Movies have images and sound, play (not playing games) have fun and emotional content (fun), books have plots and stories, but games have rules. Thus gameplay must emerge (or be a part of) the rules.
