The concept of video games as a form of art is a controversial topic within the entertainment industry. Though video games have been afforded legal protection as creative works by the Supreme Court of the United States, the philosophical proposition that video games are works of art remains in question, even when considering the contribution of expressive elements such as graphics, storytelling and music. Even art games, games purposely designed to be a work of creative expression, have been challenged as works of art by some critics.
