I have read many books and seen many movies that I feel are worse artistic works than the best games, but I also think it's a hard comparison to make.

There is no music that compares to "War and peace" or paintings like "1984", nor is the movie "Alien" like any book. Describing H R Gigers monster design with words will not have the same artistic impact.

I think different creations can be be great artistic works on entirely incomparable axes.
