I am really happy with the scale of the game. You can zoom out to enormous heights and see your bustling city below you, or you can zoom into an individual citizen walking the street. The better your card, (duh) the better this will look. Point is, it is worth it to look at it with the settings all of the way up.
I would have to place the music somewhere between bad 70's electric music and a cheesy sit-com. There is plenty of diversification in the sounds to let you know when they are trying to get your attention in order to point out a situation you need to address. But, the music may best be turned off later.
