music makes a difference

I wouldn't say that music is more important than gameplay. Music is more emotionally connected than gameplay, and is more tied to memory. However, these matter little during the actual playing. They create fond memories and will bring you back to play more, but they will not keep you playing.... There are plenty of games I found myself just standing still listening to the music, because the gameplay was distracting from the listening.. This isn't good... It is because the only part I was enjoying was the music.

Music and sound effects are an integral aspect of games. But they do not trump the gameplay. For, without gameplay, you made a movie.
