I think they can be considered an art form. But the perception that people have about videogames is that it's a hobby for teens and young adults to kill some time. The VGX awards certainly don't help videogames image as an art form.

It´s up to each one to decide. Some games give strong arguments to that,  like Flower, Journey, ICO and Lost In Shadow. While they do bring some challenge, their aim seems to be evoke feelings on the player. And this is essentially what art does. 

Great observation. Let me add something:

Not only that but the way the so-called videogame press treat it.  Videogames can be appreciated, but they are also business. And while art is meant to be appreciated, art is also business. Unfortunately, videogame press do not adress those issues properly, instead  they prefer focus on reporting every fact related to videogames from a mindless and biased point-of-view, instigating controversy and fanboyism, rather than presenting it to people as a valid form of entertainment that has options to suit every person tastes and feelings, just like movies, books or music. Unfortunately this isn´t happening, despite of the size of the market, a good part of our society still don´t see videogames as a true and acessible entertainment option

Of course. Same way Michael Bay movies are art.

lol

Yes. Games are a form of Art.
