A video game is art; through extended exposure to a group of mediums creating an interactive experience!
As an example, The Elder Scrolls V: Skyrim, has very detailed landscapes and character development. It uses music from Lindsey Stirling, who is a violinist known for her epic melodies and dance moves. The storyline itself is a work of art: it interlaces all aspects of this fictional world into a tightly woven adventure! The animation process, like clay modeling and work in Maya, is also a time consuming art form that requires a very high level of skill.
The game’s merchandise like clothing, strategy guides, and posters are types of art. Websites, forums, blogs, movies, even the structure of the platforms and their controllers, were all designed to be appealing to the audience.
When these elements are combined to create a greater work, they do not lose their artistic value, but melt together to deliver a greater piece with interactive dimensions.
On a personal note . . .
. . . seeing as how I’m planning on becoming part of the video game industry, I would be pretty offended if my work wasn’t considered art by some type of following.*http://dictionary.reference.com/browse/art?s=t
