This is an effective suggestion, and would definitely improve gameplay, but you have to remember, there are some limits to what the BIS team can do. First, CPU power. You don't want to create a great game, but only have the top line computers be able to play it. Second, the size of the development team. This is obvious, but the less people, the less able to be done by a deadline, and if they try to put to many things in, they will have to hold back the release, and "Casual" gamers will move on, and less people buy the game... you see where I'm going with this. There are many others, but I'm sure you'll think them up. Anyways, to conclude my idea, I would love to see this, but if they don't, it won't be a total game breaker.
