^ I believe that need to be connected to the Internet at all times is necessary because a core component of the single player game (from what I understand listening to the Giant Bombcast) is that expansion of your city requires you to work with another player in order to do so.
You're well within your right not to buy it because of online DRM, in fact, I hope more people like you do the same. Only way EA and other companies like them will ever learn is by voting with our wallets and not buying it. Granted, video game piracy is a bad thing, but this isn't the way to go about it when you're inconveniencing the consumer like this, treating them with contempt. There are plenty of other sim-city-esque games out there which don't have it and, again by my understanding, are better games than this. Cheaper too!
The other thing I don't like about this is the fact that the game is so dependent on the server side of things that maybe 4-5 years down the line, when EA pulls the plug and stops supporting the game to make way for something else, your game is practically defunct. You can't expand, can't play with others, hell you might not even play the game at all because the online DRM will fall over. It's so dumb!
