The television show "Mr. Robot" provides a very good example of how to get the most of a scene. SPOILER ALERT in this episode and this description! In episode 9, the show reveals that the antagonist is actually a facet of the hero's split personality. In the scene where it's revealed, they use music that not only reflects the protagonist's state of mind, it also references Fight Club, a movie with a similar story reveal that used the same music. With this simple choice, they have created both an internal reference - the mindset of the character - and an external reference - the similarity to Fight Club - which come together to form a richer interpretation for the viewer of the show. Let us know in the comments about games you've played that also manage to pack multiple messages into a few simple references!
