IMHO, very few games can be qualified as art. In most case, videogames are a pale copy of an technically innovative games. What you see, what you hear, it's nothing but 0s and 1s and the real game artists are the ones who allows other artist to showcase their own art with the fewest limitations.
The only ones capable of making videogames an art, are the ones who make them. Until programmers publicly showcase their code and that can easily be admired and appreciated by non-programmers, videogames will remain a medium to showcase other people's art.
