Navagon: Art is that which is created with the intention of creating art. It's entirely dependant on the intentions behind the creation.
Typically with games there are a great many priorities that supersede any artistic intentions. That is not to say that games cannot have artistic elements but it is more often the case that artistic skills are employed to create something which is, as a whole, not art.
are you an intentionalist as far as artistic meaning as well? as in, do you think that the only meaning a piece of art can have is that which its creator intended?
as for answering this thread's question: games currently are not art, with a few exceptions. their
potential to become art, however, is impossible to deny. the fact is that it is possible to create--visually and audibly--anything within a game that can be created visually and audibly within other artistic mediums. therefore, we certainly do need some game developers, as navagon said, who intend to create art (although I don't think that is a definition of art)
games even have one incredibly useful new feature that other mediums do not have: they can force you to experience something, or to do something yourself. that is incredibly powerful. imagine the emotions you could illicit from someone by, say, tricking them into doing something they will later deeply regret, or any number of situations you could create within a game.
also, games can comprise entire new worlds, and can react directly and concretely to the viewer. how many other artistic mediums can claim that ability?
i intend to be one of the incoming wave of real artists creating real art games once i get out of college.
Snickersnack: If nobody can agree on a definition for art, why bother classifying things as such?
*goes back to Redneck Rampage
i keep coming back to this too. that's why i usually try to focus on the capabilities of the medium when making this argument.
