Farmville?

Paula is playing an online game called Farmville at Facebook. The object is to grow crops, that can be sold so that other stuff can be bought and the farm can be developed. So far, she mostly grows strawberries. I cannot understand the fascination of this game. It would be completely different if she would have a pig farm or something like that. Since it is a computer game, thus a bit unrealistic, I would also like it if meatballs could be grown. Berries are not as cool, because meat is much tastier than berries.
