If you've played the previous entries then you know what this game is all about. There were a few changes to this installation that manage to keep the series interesting. A lot of the goals and mechanics are the same. That's not to say this is a bad thing at all, quite the opposite considering it has been done well each time. If you enjoyed them before you'll enjoy this one. If you've never played any of the previous games prepare for something that can take a lot of your free time depending on your style of play.
