36. While most of the playable cast have their main themes playing while they are introduced in the story, Terra, Celes, and Sabin do not. Terra has the them Awakening playing during her formal introduction, Celes has Under Martial Law, and Sabin has Coin Song playing instead of their actual themes.
37. Speaking of which, VI is the only game in the series that introduces the cast through a narration.
38. VI has the most glitches in the entire series with only FFVII coming close to the amount of weird stuff that can happen to cause strange effects.
39. VI is the first game in the series to have two party members who share a parent/child relation. (Shadow and Relm)
40. VI is the second of three games to have twins in the story as main party members. The other two being FFIV and FFXII
41. Umaro was suppose to be recruited differently in the original plan for the game, he would be a rare random monster on the overworld map you had to defeat to get him to join you.
42. Gogo as well had a different scenario for obtaining. He would dress up as a party member not currently in your party in the WoR be found randomly in towns. You had to get the party member he was mimicking and try to find him before he left town and took another members persona.
43. Even Sakaguchi and Kitase admit that Gau really has no point in the story, but they wanted to make him anyway.
44. When asked about the fates of Banon, Arvis, and the Narshe Elder in the WoR, Sakaguchi has stated the player should use their own imagination.
45. VI is the only game that has a summon that can hurt it's caster.
46. Speaking of which, VI is the first game in the series to have black magic spells that target the whole party. Though V is the first game to actually have a spell that affects everyone...
47. It wasn't until Dissidia that we finally got an age for Kefka, and I believe him and Vayne are the only main villains in the series that actually have confirmed ages.
48. VI is the only game in the console series, where the Flametongue and Icebrand weapons randomly cast their elemental spells when they attack. It is also the first game in the series to have the Thunderblade (not to be mistaken with the other Lightning based sword, Coral Sword)
49. VI has the longest Final Boss theme in the series (17:38) and the longest ending theme (21:34).
50. Final Fantasy staple, Cactuar made their debut in VI.
51. Though Tonberries debuted in FFV, VI debuted the stronger and meaner Master Tonberry, though it wouldn't be til VII that they acquired their two signature abilities: Knife and Everyone's Grudge.
52. Gau and Gogo cannot use the Merit Award in the GBA version of VI cause SE learned about "Wind God Gau".
53. If you get a characters magic stat to 140 or higher, the damage from magic will overflow and cause it to be reset to 0.
54. AP has two uses in the game, it's the currency point system used to learn spells and it's also used to determine how much time Terra can stay in her Trance mode. This is why even if you have learned every spell, if Terra is in your party, you still get a message that you got AP from the battle.
55. Nobuo Uematsu considers VI to be the last original Final Fantasy, as many of the core members from the previous entries either quit Square, moved into administrative positions , and the team was replaced with younger members of the company or new people.
56. Nobuo also didn't like writing a theme for a cast so large cause he felt that some would not be as important to the story as other.
57. VI is the first game in the series to have secret characters to recruit (Umaro and Gogo).
