Video game products contain plenty of art, but it's product art, which is to say, kitsch art. Kitsch art is not bad art. It's commercial art. Art designed to be sold, easily and in quantity. And the bigger the audience, the kitschier it's gonna get.
People who talk about "Kitch" art are generally the kind of people who think that true "Art" consists of splotches of paint on canvas and rusty iron walls. I'm not going to dwell on this, but I will add that yes, some art is crass and cheap.
For as long as we've had 'modern' art, it's been popular to refer to it as monkeys painting on canvas or sperm, blood and shit in a blender.
In the old times being an artist used to mean the practical skill in painting, sculpting or the like. These people didn't do 'art' just for fun and for grants, they were employed by people who wanted something (usually themselves) immortalized. Anyone can appreciate the magnificent craft of these paintings and sculptures, but they could truly be understood by fellow practicioners or experts that can understand all the different nuances.
Computer gaming example, consider bullet hell games. Before 'shooter' came to mean FPS, vertical and horizontal shooters were popular. After their descent into oblivity, the genre was transformed into its extremes, with literal curtains of bullets and mind-boggling difficulty levels. Eventually that did turn everyone expect the most fanatic hobbyists away. If you'd say 'shooter' to a child from this gaming generation (s)he would think about a game where two fratboys do fistpounds after killing deveral dozens of people.
(the above is not demeaning, I like ridiculously macho killfests as much as you do)
But some art is heartfelt, and worked hard on, and that shows through in the final product. And there are video games which meet that standard.
Forementioned shooter genre received several of its finest contributions after vanishing from regular gamers' eyes. These could be appreciated (or even known) by only hardcore fans of the niche. Yet they're undeniably brilliant.
The point is - if you don't understand something, that does not make it not be art. I'm not saying that killing cats on video is art, but even among the paint splotches, there are people who are masters in their craft. Perhaps people who are into rusty walls can see something touching in a particular installment. At which point, it is art.
Conversely, even if someone does not understand gaming, it still is art. Simple as that. Perhaps not every game or even the most, but there undeniably:
I think most people on the forum will have played a game--however primitive--which moved them deeply in some way. And moved them in a more genuine and heartfelt way than any picture of circles has ever moved any art critic.
There's already been many great examples in this thread. I'll add The Void.
