Today McDonald's partnered with game developer Zynga to become the first marketer to integrate a branded farm into the Farmville Facebook game. In the one day event, McDonald's is hosting a "Neighbor Farm" that players can interact with. There, they can help grow tomato and mustard seed crops and earn virtual Farmville McCafe Consumables that will increase their energy and allow them to farm twice as fast. They'll also be rewarded with virtual McDonald's hot air balloons to fly over their own farms.
