XIV does this a couple of times. There's one during the fight with Bismarck. You have to protect the island you're on. If the island's HP reaches zero, he eats it with you're party.

And speaking of going through doors you're not suppose too and causing a game over. I'm always a little disappointed in V when you're going through the towers and if you make a misstep, it's just over. Nothing special happens. Just game over.
