Leigh Alexander has a great post up at SVGL that will hopefully galvanize the resolve of those who want to follow her call (which fits well, actually with what N'Gai Croal is doing these days).
As I wrote in Leigh's comments, I think she's a little hard on COD4, which I think deserves a lot of praise for doing what it does. Weird story from left field: Herodotus tells us that a tragedian named Phrynichus was fined by the Athenians for putting on a tragedy about a real disaster (the Capture of Miletus, but that's not important now), because the audience felt that the suffering was too familiar. It seems to me that distance is necessary, and helpful, a lot of the time.
But the basic drive to which Leigh calls us, to become better gamers, gamers who keep thinking about how our games, despite being played in an imaginary space, have everything to do with what we are and do in the "real world," is something we need to think much more about.
