Legs are made of food.

It suddenly becomes clear why cities aren't being created.

        public void Write(ITileMapCommand command)
        {
            // Use region data and construction knowledge and shell map

            //DANGER
            // For now we always assume the center of city
            // There's no method at all for using other shellmaps that
            // the city might cover.
            //DANGER

            // Need access to the shellmap.

        }

No code!

EDIT: Going to be in Osaka for the next few days.
