Legendary film critic Roger Ebert once provoked the wide community of gamers by asking the question: Are video games art? One of his key arguments stated that video games aren’t an art because the audience had too much control over the outcome of the protagonist.
A long time ago this argument was brought up about movies, and before that about theatrical production. The key argument then was: Is it art when it’s created through collaboration? Often the directors get sole credit for a film’s artistic style, but many key positions include: writers, producers, editors, production designers, cinematographers, all the way down to the makeup artists and set decorators. Some more minimal than others, all have an artistic input to the production of a film.
Much like films, video games are a collaborative art form. Some games have reportedly taken over 5 years to fully develop.
