Just a quick link that carries the announcement from the US Army that they are moving their "video game" to the Xbox 360. They emphasize the "realism" of their games. My favorite counter-intuitive quote from the games developer "IGN: Will the single-player have gamers facing realistic situations based on the current war in Iraq or are you staying clear of this? Greenback: We are steering clear of any current Iraq situations as well as any other real-world scenarios."
That's the ticket, we want to use the game to teach tactics, but we wouldn't want the "realism" of war to get in the way.
