Ben Kuchera writes a compelling argument for why select games should be considered art (though before I read this Rock Band was not necessarily in that list). This was my favorite part:
This is why you can’t argue for or against games as an art form without taking the time to play through the games themselves. I’ve seen clever people at cocktail parties claim that a few shapes on a canvas can’t be art, and this is usually combined with a sneering contempt for what passes for “art” in our modern times… although it seems like that argument has been going on for the past century or so. There is an intense difference between seeing an image of a Jackson Pollock painting in a book and coming upon a Jackson Pollock painting in a gallery.
