When I saw the DLC trailer, I had completed roughly 70% of the main game. I cried, "Yes! Clive, Jill, and Joshua are all alive and well!" I was especially glad for Joshua because he had been coughing up blood throughout the main game, and I figured that by the end of the game, they would have found a remedy for him. But we were all aware of the conclusion.
It's not a bad story, in my opinion. Clearly a significantly better story than Final Fantasy XV.
