Many FF games don't refer to the 0 HP status as being "Dead". Final Fantasy IV calls it "Swoon". I think 0 HP just means that you're so damaged and exhausted that you can't fight or even be of any help in battle. I think it means that if everyone in your party was in that condition, there would be no one to stop the bad guys from finishing you all off in your weakened state.
Even so, I've often dreamed of a world, something like the worlds we see in FF games. Being into video games like I am, I never fit in much. At my schools that I attended, it was all about being Mormon or being a football player, and I was neither. I was addicted to Final Fantasy. I was always a bit of an outcast.
I'd often think, "What if I was chosen to save the world? What if the world was being threatened by some really powerful entity, and I was called upon to fight and save the world?"
As an outcast, I'd dream this sort of thing up, and even write the entire story of my triumph over evil. And I was considered a hero for it. I was no longer the stupid high-school loser that I actually was. I could be a Paladin or a Mage and use mythical power to save the world that had been so judgemental of me.
I felt like if the world was more like the FF world, I'd probably be a lot better off.
But alas, the world is as it is, and I've learned to adapt and forsake the ideas I once harbored. And I did hope it would happen, too. I knew it wouldn't happen. But I hoped it would.
