What is SimCity and should I buy it?

Really what is involved is what you think. You build cities. That's it. You do have to make sure everything has access to utilities and there's a few types of buildings available but it's really just a city simulation. You watch it grow. Tax the citizens. There's not a whole lot of difference between the different versions either, they are all about the same (build cities), just graphics quality and some quality of life adjustments with some of the controls. I make it sound so boring but it's really not! haha! It's worth it at those prices and if I would you and you can afford the extra couple quid you might as well get it all. ;)
