What was it called... The Path, I think (but don't quote me on that, I'm thinking of the game based on Little Red Riding Hood if I got the title wrong). Someone should direct Mr. Ebert towards that and tell him that he's being silly. Plus, he has no particular authority as an expert on games. The games that he'd see from outside gaming culture would be things like Halo, Call of Duty, or Gears--hardly art. I think he should have done a bit more research into games with complex plots, settings, characters, environments, creative ideas, emotions, etc. before making blanket statements about an entire medium.
Off topic: that song is terrifying. It's also quite obviously one of the most accurate portrayals of gamers ever. After all, isn't Xbox Live a community of whiny 12 year olds?
