Have you ever played a video game that included food to eat as a source of energy or incentive? If you do play games, you know how common that can be. In World of Warcraft there are strudels and biscuits, in Castleville there are cupcakes and donuts, and in Portal there is a delicious chocolate cake. Now, how many times do you start craving these types of foods as you play these games? I am personally guilty of these cravings, and have gone out of my way to purchase a strudel or two, as a result. What are the chances I would eat these foods if, instead of cakes and donuts, the games used strictly healthy foods such as granola, fruits, and vegetables?
