Although not exclusive to the medium, one of my favorite things about video games is how many elements are includes within a single work. Everything from level design, artistic style, story telling, cinematic direction, music and numerous other bits contributes to the title as a whole. Each aspect can pull from different inspirations as well as individually succeed or fail, while still coming together as one product.
The game-focused aspects of video games are likely most important to the majority of people. However, sometimes developers simply use them as a vehicle for the overall experience rather than the main draw.
