Honestly, this is more due to the translation than the actual writing.
FFVI came out in a time where Square just did not give a fart about its western branches, leading to such nonsense like just not giving translation teams the actual script of the game. Often, the team had to completely play through and copy down text or reverse-engineer what they could in tight time restraints to get dialog in code, resulting in utter messes of scripts. This is why sentences all the way into PS1 era Square games already read strangely, and a lot of meaning and tone was completely lost.
The best example of this is the ridiculous scene in FFVIII where the time witch gives a speech to a cheering crowd that amounts to “MUAHAHA I AM EVIL” except that’s not at all what she was saying in the original script.
FFVI is kind of important because games on consoles at the time barely had stories. Like, when IV came out, it was revolutionary just because it had an actual narrative and script alongside graphics that actually looked like things. When VI released in 1994, nobody in console markets had ever really seen something with that much narrative (and it’s still a solid amount by today’s standards) or ambition, and the fact it managed to accomplish a good deal of what it set out to do, even in that butchered script, was kind of mind blowing.
Now why it’s still so badly translated in re-releases and updates is entire on Square Enix just not caring.
It’s not a thematically complex game (honestly Square is pretty bad about that with most of their games), but it has a great understanding of character and engaging the player. It is ridiculous for people to treat it still as some writing high benchmark (and boy oh boy it does not deserve that), but I think you’re not giving in the credit it really deserves.
FFVI literally changed how stories in games were handled. You can still learn a lot from examining what it does right, particularly the pacing of the first half and defining characters right away from their initial intro scene.
Guess I’m rambling at this point but I’m just saying that sometimes you gotta respect the classics.
But Chrono Trigger is legitimately written bad outside two party member side stories and is vastly overrated kthx
