It never occurs to the citizens to run away from the general area they are in. "Hey! Let's run around this building multiple times instead of running to safe-house or bunker of some kind! We'll totally be safe!"
i found out something really sick. in the free-for-all games people would type in vagina and other inappropriate things like that, and then an ACTUAL pic of said vagina pops up. My god, children play this game!
Like some people said already, it would be nice if the next version of the game allowed you to see the elements you created in action. Watching populations and animals grow, and even some elements automatically reacting with each other.
