Hm, some of those answers I have to call out as incorrect. Also, if there is more than one correct answer, but you list only one, do the others still count? Like the FFIV reference in FFX - Magus Sisters is one, but there were two other definite FFIV references given as answers (Kain's Lance and the spoony bard line).
A single Wild Nakk does not give 625 gil in FFV, it gives 125. 625 is the total you get for killing a group of five Wild Nakk.
You can, in fact, fight three different Abductors three times. The island trap, Val Castle gates, and Exdeath's Castle in the room where you have to time the switch to line up the moving path with the exit. If the path lands in front of a pillar, a monster pops out and attacks you. Each pillar has a set monster that will appear from it. In fact, you can repeatedly trigger the pillar trap that springs the Abductor on you and fight it as many times as you like.
The Geomancer is not the only job that gives all positive boosts in FFV, since the Mystic Knight/Sorcerer also gives all positives, as do the Advance-exclusive Necromancer and Cannoneer.
Cloud's birthday is only the 19th in the instruction manual, which is riddled with errors. All other, more authoritative sources, confirm his birthday is supposed to be the 11th. Since the instruction manual, shoddy as it is, does say it, I would count both as correct, though.
Reno's last name is not Sinclair. This was taken from an unofficial doujin (japanese fanfiction) and got spread around, but is completely untrue.
The Shinra conference room is on the 66th floor, not the 67th. 67th is the science floor where all the Jenova and Red XIII shenanigans take place.
Only the cyborg Esthar soldiers are weak to lighting. The human ones are weak to poison.
Jobless Jeff is Jeff's textbox name before he gets together with Part-time Worker Mary. Once they open up their shop together, he is known as Part-time Worker Jeff from that point on. Don't know if you didn't count that or not.
Same with the Zodiac Spear question. Are you counting Henne Mines or not?
As for the ability all monsters are immune to in Tactics, why Hellcry Punch specifically? All equipment-breaking abilities (the regular Knight ones as well as Meliadoul's and Orlandu's special ones like Hellcry Punch) will always fail on monsters. Also, while researching this answer I remembered that all equipment breaking attacks still work on monsters in the War of the Lions version of Tactics, and just do damage instead of breaking equipment. Also, there is, in fact, one attack that monsters truly are immune to in all versions of the game (which I did not know until I looked it up) - The Wildbow's Nose Bracelet/Snort attack will only work on humans.
Izlude does have Maintenance as one of his set abilities, but Elmdor's job class has inherent Maintenance, making him also immune to stealing or breaking equipment. The only version where this does not work (possibly due to a glitch) is the English Playstation version. In the original Japanese version and the War of the Lions version, you cannot steal Elmdor's much-coveted Genji equipment and Masamune.
As was mentioned, Bandersnatch and Jabberwocky are not the only Woodwraith-type enemies in FF13, with Enki and Enil being the first Woodwraith-types you fight.
I have no idea where that name of the Law card from FFTA is coming from. I booted up the game and tried to find such a name, but the cards are called what I remembered them being - simply the name of whatever's forbidden. The card that forbids items is simply called "Item". I even watched a
playthrough on youtube of the beginning of the game and the battle in question, and the Judge never calls the law anything particular. Googling the term "R2-4601 final fantasy" brings up a site called funtrivia.com as the only place where the law is called that, which also has many of the other suspect questions as well. I'm assuming you pulled many of the questions from that site, but, unfortunately, it is not a very reliable source and more than a few of its answers are inaccurate or flat-out wrong.
Hate to be "that guy" but, well, heh, I am that guy. Trivia. Serious business, yo.
