Art is art and games are games. Different things. Why is it so difficult for some people to see that? I think it has to do with the fact that most of us don't have a clue anymore what art is, or our relationship with arts is minimal. A big number of artists have worked in the Buckingham Palace, painters, sculptors, architects and others, but that doesn't make Buckingham Palace a work of art, but a building. A nice building, but building. The same goes for games. No matter how artistic one game might be, it's still a game and its purpose of existence is to be played.
