A game for change? Another goodie via Boing Boing:
"Paolo Pedercini is a mad bastard, and the McDonald's game is his sharp, procedural satire of how fast food is a corrupt industry by necessity. The game is set up so that you cannot win without compromising. Try it, you'll see. While you can maintain mild growth without using hormones or genetically modified crops, your bosses will not be satisfied. To really succeed, you have to employ what some might call "unnatural" means, though at Corporate, they call it "McFriendly growth measures".
