Video Games: Art?

The question over whether video games are art or not is widely debated. Usually when approaching the discussion, one starts by defining art. I tried this as I read through Ebert's article, thinking of how I defined art. Whatever words I spun in my head; however, I couldn't come up with a definition that was all-encompassing. I was given some clarity after reading Stanton's: simply put, art is undefinable.
 The traditional definition given in any beginner art class has something to do with expressing yourself. Designating a single universal interpretation to art defeats that purpose, I feel. As a matter of fact, why is that question brought up so much in those classes? Perhaps it isn't to find an answer, but to make the students think. "Art" is just a word, the concept we attach it to is subjective. "Beauty is in the eye of the beholder" and all that jazz.
In this case, Roger Ebert is right. Video games aren't art. To him. So why does that matter?
It's a case by case basis, really. I for one do believe that video games are art. They arouse feelings in me while I play, and lead to a world of endless imagination, the same world that spawned the creation of the particular game in the first place. Perhaps art is meant to nurture creativity; in which case, almost anything can be art. Interior decorating is art. Talking is art. Hell, you can make macaroni art.
So by my definition, any video game is art. That being said, some art is better than others. For every Citizen Kane, there is a Troll 2. And for every Legend of Zelda, there is a Superman 64. But should one bad apple discredit an entire medium? Of course not.
I don't think we need to focus on asking whether or not video games are "art". You already have that answer. Instead, we should ask if the qualities that we prize in "art" are present in video games. Evoking harmonics from music, resonating images from cinema, endearing characters from literature, and etc. Are they used effectively in the game? Do they make it more fulfilling to play? Or, you can choose not to analyze a game, and simply enjoy it for what it is.
That's not nearly as thought provoking though.
