I suppose at the moment there's no real consequences for not keeping your dinos fed, apart from the whole gradual dying. It does sort of make me wonder why they don't try to break out generally.
Yeah, it always was weird how a giant predator would starve if there is no food option in her exhibit, but would break out and eat guests if there were not enough trees. I think having the predators at least break out and attempt to eat the guest would make sense as how carnivores are more dangerous than their herbivores besides the already high chance of them breaking out during a storm.
As far as I have experienced, the only times dinosaurs every break out would be:
• If they are mission dinosaurs that would require them to be triggered to make the mission difficult.
• If their comfort is low because:
- Habitat needs not met
- Social and population needs not met or exceeded
- Have a storm trigger their comfort need
- 100% comfort threshold
• If there was an opening from a poorly made exhibit, from gates being open, or from a tornado
I think including breakouts because of being too hungry would make sense at least for the carnivores. That way there is a much bigger risk if their hunger has not been properly satisfied, making their danger factor justified for the often higher star rating the herbivores would not be able to provide by default.
