I think bad neighbohoors are worse than any of the precious SimCity disasters.

Talking about disasters, you can't turn it off, which I find a debatable design choice. I am the only person which played with disasters turned off? I always found the odd earthquake or alien invasion just too random since these are not common where I live, specially the alien invasions.

But the gist of it is, SimCity is a game about planning and building, and it turns very frustating when you add the trollish human element to the recipe.
