SimCity for Mac is an excellent and impressive game. When you're zoomed in, the detail and animation is great even down to each and every resident that seem to have their own personality. SimCity looks great and you can make the game look the way you want.
You can even learn about every individual resident's wishes and concerns, obtain stats on almost anything and check out neighbors to see how they might complement you or offer you services.
Sim City for Mac is beautifully designed with an incredible amount of information and detail that really brings your city alive. However, the biggest gripe with Sim City for Mac is that you cannot play without being connected to EA's servers which had several teething problems on the PC version and it's shame that you can't just play offline. Whether you prefer to play alone or with others, it's enjoyable, but it's clearly designed more with multiplayer in mind. However, the cities are limited in size, and SimCity is more fun when you have multiple cities that cooperate and specialize.
When you start Sim City, you can either join a populated region which will have other online players in or start a fresh region yourself.
