In part because what is engaging about it is not vested wholly in its aesthetic value. This, of course, does not necessarily preclude a work from being considered art. I think my refusal to consider games of this nature, or indeed games of any sort, as art comes down to the medium. Literature extends literature in a transcendent manner, putting like into a like medium that is wholly expressive and formally complete, whereas games of fantasy enrobe themselves in the trappings of purely aesthetic mediums; but the medium of games leaves room for gaps in its progenitor’s sublimer forms. This is only one man’s opinion though, I concede.

I tip my fedora to you, good sir.
