I agree with Vivi completely. The 'whole' is what determines whether or not something is a work of art, not the individual parts. I think Final Fantasy is a good example of this. In my mind, Uematsu is an artist without question even though I cannot say the same for most of the games themselves. There may not be a universal standard for what constitutes art, but there is one aspect that nobody can deny and that is that art is the synthesis of elements. When the individual elements in a work do not synthesize well it is either A) bad art or B) artless. I generally go with option B because I refuse to accept that every last thing ever created is a work of art but some people obviously disagree.
