I'm sorry, I have to share my heartbreak. This is heartbreaking. Don't read further if your heart is at risk of breaking. Consult your doctor before attempting to suffer through heartbreak.
To preamble an unnecessarily excessive amount, a few years ago kwhazit did an AMAZING, step-by-step, detail-filled, context-providing, wonderfully thorough translation of FF6. Like, the entire game: dialog, attack/item/spell names, monster data… more information than you'd find even in an official strategy guide. Should they ever read this, I hope they know how much I appreciate all of the work they put into it, and it's quickly become one of my primary reference sources when looking up something about the game.
Since they included translations of everything, they also included translations of events that may not usually be seen in the game, such as when you fail at a critical event.
FOR A HEARTBREAKING EXAMPLE, it's possible for Sabin to die in the World of Ruin if Celes does not rescue the child from the collapsing house in Tzen quickly enough.
The incredible @wsancho wrote an excellent post on this particular event and how the "failure" option was softened from the original concept (again, consult your doctor before reading their post about twin death).
In the final version of the game, failing to rescue the child in time results in a "fade to black" Game Over screen. Nothing is shown, only implied (thank god).
What I didn't know until recently, [no] thanks to kwhazit, was that Sabin has last lines before the house collapses on him.
The two translations definitely have different emotional weight to them. To me, Woolsey's translation's conveys Sabin meeting his demise with confidence (dare I even say optimism?) that Edgar will continue fighting to rebuild the broken world.
Meanwhile, the original Japanese text (through kwhazit's translation) feels more layered to me, like he is pushing himself to the very last moment, is angry at himself for not being stronger, and is feeling regret that he won't be able to help Edgar anymore.
So, not only does Sabin die, but his final thoughts are always about Edgar. 😭💔
Outside of the game, I think this would be true for Sabin in any scenario, even if he lives to be 94 years old and dies peacefully in his sleep.
And although I love the idea that Edgar's final thoughts would be about Sabin, I'm actually not sure they would be. Again, as wsancho points out in one of her amazing braindump posts, Edgar tends to focus on the welfare of his kingdom above all else. Because of this, I think that his final thoughts could be about Figaro and its future. Perhaps it depends on how well he thinks the kingdom would do without him.
None of this matters, of course, because as far as I'm concerned, both brothers live forever and ever and never die or suffer and are always happy and thriving END OF STORY.
