To totally counter my idea of Meat Bricks (which I still want) and in regards to stoot's mention of the concept of needing to vary one's diet...
Beans made into tofu which would be used in assorted "meatless and dairyless" meals. Personally, I am not a carnivore, but I imagine some players would like to play to there own tastes. I would hate to see them forced to eat virtual meats just to get virtual protein.
