This expansion includes earthquakes, thunderstorms, tsunamis, forest fires, tornadoes, sinkholes, and meteors that can wreck havoc on any mayor's city. There are also new disaster-oriented buildings, a scenario creator, and helicopters introduced. Gameplay reaches a whole new level with this expansion.
Natural Disasters does not offer anything to improve one's city. It only offers destruction and buildings for citizens to seek refuge in. Some players complained of citizens moving away after disaster strikes. And of course, destroying one's city means that the buyer must spend their time and effort rebuilding it again.
You are an individual who enjoys "playing god" and causing death and destruction.
