Roger Ebert said some time ago that there are no video games that can compare with the great works of art in other mediums, such as poetry or literature or film. What kind of comparison is he talking about? Looking at more established art forms, it seems clearly nonsense to compare something like Beethoven's Ninth to Shakespeare's Hamlet, being so radically different mediums - yet we don't say that no play has yet matched any of the great musical compositions of our culture, or that no poem can compare with the great sculptures of the past.
On what level, then, are two works from different mediums (like the Ninth Symphony and Hamlet) comparable? Is it just in there overall quality, and if so, how does one judge the overall quality of a work of art, independent from those features that set it apart from other art forms? It doesn't seem fair to say that Hamlet has more psychological depth than the Ninth, or that the Ninth is more harmonious and evocative than Hamlet. Is it, rather, a question of comparable contexts, comparable status and recognition, comparable influence?
