Makes you wonder how big the Country will be if they add 20 cities to California. Granted many states like those in the Midwest would generally have 2 or 3 decent cities to add. But states like Texas would likewise see large numbers of cities. This would make for a huge American map, and we haven't even begun on Canada or Mexico if they are expansion possibilities.
That being said, I am looking forward to this game and hope to see many of the stuff asked for in the wishlist.
