This should have been a poll thread.
But, as to my two cents, I agree with Ebert.
As much as I love playing my videogames, I have never been inspired, emotionally influenced ( with the exception of mild happiness in beating a level) or particularlly impressed on a cultural or social statement level.
While I agree that some video games are visually well done, and some may have impressive storylines, it does not qualify them as "art".
At best, videogames are a poor attempt at art. I don't know whether it's the medium, or the games that have been developed so far, but I am hard pressed to think that videogames will ever be eligible for "art" consideration.
Alternatively, I can compare Schindlers List, Van Gogh's paintings, and the works of Mark Twain, as "art" on various levels. No videogame I have ever seen, played, or heard of, comes close to being in the same catagory as the examples I listed.
