A friend of mine, Jeremy Bernstein, is a writer/game designer living in LA; he's done some work in political games in the past with the aptly, if unimaginatively, named Redistricting Game (www.redistrictinggame.org). Now he's put together a game targeting all the dirty, dirty lies being spewed out of the presidential campaigns.
I'm fascinated by this stuff, because I'm always a little puzzled why we don't use the addictive nature of gaming more as part of an educational technique.
The game is called Truth Invaders, www.truthinvaders.com. If you enjoy it, let people know, 'cause this kind of thing is all the publicity it's gonna get.
And so we keep it participatory -- in the Comments, favorite computer/console game of the moment. Bonus points for obscurity or age.
