It would be kinda cool if a dinosaur, lets say a Tyranosaurus(or any other dangerous carnivore), breaks out of containment. If the player is unable to stop it and it kills to many people, then it is decided that the park must be shut down. I know that it would probably not happen, but wouldn't this be a cool feature. It would be kinda cool to see, it may be very unlikely but also something I would like to see.
