Two piece of food for thought. The first, from Roger Ebert about why video games are not and can never be art. I know a lot of Ebert fans read this blog, and I count myself in their number, but I have to say that I thought this essay was very poorly thought out and read like it was by someone who hadn't seen or played a video game since NARC.
Ebert's arguments against video games as art are: (a) to constantly redefine art so narrowly that most movies he likes don't qualify, (b) to claim that if video games became art they would cease to be video games, (c) to argue that many video games have rules that are different from chess and (d) to argue that because you can win a video game and can't win a novel or film, it's not art while not realizing that with many current games you don't beat them or win so much as you finish their stories, with completing tasks being the way to unlock the next part of the story... Ebert's clearly not aware of the new vogue in video games for sandboxes and decision-tree plot development a la Fallout 3 or Mass Effect that expand what it means to finish game).
My gut instinct is that video games are not art, but I have no real arguments as to why that is the case. Although I'd be interested in your thoughts in the comments, dear reader. I do know that Uncharted 2 is at least as compelling as any Hollywood blockbuster released in the last year or so, and is certainly much much better on every level, including acting and writing, than Indiana Jones and the Kingdom of the Crystal Skull, which Ebert gave 3.5 stars to.
So I offer instead John Lanchester's article about video games and whether or not they're art in the London Review of Books.
In it, Lanchester mentions that the best recent fictional commentary on Ayn Rand and Objectivism is the first Bioshock game. If people are interested in trenchant fictional commentaries on Ayn Rand and Objectivism, I would also highly recommend the satirical science fiction novel Sewer, Gas & Electric by Matt Ruff. Particularly if you happen to be a fan of early-career Neal Stephenson, you'll get a kick out of SG&E.
