Creation of games like Skyrim I consider to be an art, but because of the immense size of the in-game world, it is not perfect in all respects, like voice acting, glitches, and a story that is predictable (though still very entertaining). However, games like The Last of Us or Bioshock, are nearly flawless and are fully compelling, even more so than a book or movies, because being able to control the main character adds realism.
Themes, especially like those in the Bioshock series, become more "feelsy" and apparent as well. In both Bioshock and infinite I got some serious spine tingles when I realized that the free will I had experienced throughout the game was actually just a product of either fate, or manipulation. This would not have been close to as exciting and emotional through another method of storytelling.
But then you have games like Call of Duty and such which I don't consider to be worthy of existence.
