Suplexing a train is a core childhood memory 😂

My favorite "secret" is the scene where Celes tosses a coin against Setzer.
If BOTH Edgar and Sabin are in the team, Sabin will comment " That coin... ! "
It's very subtle but the implications are huge , because the coin belongs to Edgar, and was used to bet his future.
But this shows that the coin was rigged and he voluntarily let Sabin get his freedom while taking the responsibility of the kingdom.

I wish there was more lore surrounding the 8 legendary dragons

I'll never forget the first time my friend Amir and I played FF6 and we saw Kefka win and destroy the world, we were silent, we didn't know how to react. And then the scene with Celes collecting fish happened and without knowledge we failed. 2 Kids who were 9 and 10 years old witnessed Celes commit Self Deletion by throwing herself off a cliff and we didn't know how to process all of this. So as you can imagine when Celes gets off the raft and into the destroyed world we were both terrified of playing the rest of the game when we heard the world theme of that chilling theme as we made our way to the first town. FF6 hold a special place in my heart always.

Going by the sprites and the fact one of the pieces of equipment is a tortoise shield, I'm guessing the imp status was probably called kappa status in japan

Mt. Zozo?

Never heard of it.

A couple other small secrets:
When Banon joins you as a guest, go back in the room where you started as Terra and had to talk to everyone in the Returner base. There's some dialogue there, for a room you normally have no reason to re-enter.
Every possible party member on the phantom train has different dialogue for eating food at the dining car.

For that last one with the ghost ability, this likely isn't a "contingency plan" worked in by the devs. That's how they handle the possess ability on the phantom train too. It removes the ghost from the party and the ghost can then be re-recruited on the phantom train, so it's the same behavior as when you give the ability to another character.

This game has such a hold on me all these years later. Such a gem.

3:27 "little green tortoises" is a hilarious description for kappas

the lola sidequest is still one of the more poignants sidequests we've had in the series, it just creeps up on you, fantastic gutpunch, love the characters in 6

When trying to save Cid.  If you accidentally grab a bad fish, you can just feed it to the bird.

Being a kid when this game came out means that I got to see the "Cid Dies" and "Shadow Dies" storylines (where Interceptor becomes attached to Realm) play out while being unaware of the alternatives.  Those stories were a significant part of why it's my favorite mainline FF game.

The last one is more of a programing than a punishment.
On the train. Using prosess will remove the ghost from your party, and that is programmed in the move itself, so you will lose a char when/if  you use it anywhere, and the game just check who is not on your party and put them in the airship when you return to the ship as a fall safe.

I never knew about getting Gigamesh's magicite. Then again, I never bothered with the Colosseum battles. Another secret is a Star Wars  reference: if Locke is wearing a soldier's uniform when he first meets Celes, they pretty much reenact the dialogue when Luke first meets Princess Leyla (also instead of hiding when the soldiers come out from Celes cell, he just stands still and salutes as they pass by).

Celes' "jump of faith" (as the original localization tried to frame it) was really impactful; but the following scene where she regains hope at the sight of Locke's bandana is one of the most moving moments in the game, and sets the tone for the rest of the World of Ruin.

Interesting thing about the ghosts is that, unlike all the other guest characters who occupy the dedicated "guest" slot, the ghosts actually occupy Strago and Relm's slots in the SNES version.  This is due to the fact that the ghosts join the party during a part of the game where Banon is already occupying the Guest slot and still needs use of it later, but Strago and Relm's slots are still not in use by their permanent members at that time.  This means that, should you play the game out of order (via the Airship Glitch) and recruit Strago and Relm before running Sabin's scenario, the ghosts permanently replace Strago and Relm and can be taken to the final battle.

The Pixel Remaster save file isn't limited to 2560 bytes like the SNES one was, so the ghosts and other guests all have their own independent save data in that version rather than sharing slots.  However, it's still possible to sequence-break Pixel Remaster, too (at least on the PC version), allowing for the kidnapping of the ghost again.  The ghost still behaves like a permanent party member, only now when you use Possess outside of the Phantom Train, the ghost simply dies and is removed from battle, but is still in the party afterwards and can be revived to kill again without having to re-add it to your party.

If you've been playing FF games for the longest time you probably know all this. The best thing about these secrets is that its still being shared till this day.

For a SNES game, Final Fantasy VI has a crazy amount of secrets. I've finished the game about 20 times (I know, it is one of the few SNES games I had growing up) and I kept finding new stuff every playthrough. Some of the hardest to find scenes for me were Kefka's origin story hidden in Vector and Cid and Setzer's special scene inside the broken down airship after the peace Banquet.

Still one of the greatest stories ever told in an rpg, I miss the 90s

I always thought Final Fantasy 6 was the one that should've gotten all the spinoffs instead of 7. FF7 is great, but the world of FF6 feels so much more lived-in.
