Final Fantasy is one of only two FF games to give a character a phobia (Rikku's Astraphobia), the first being FFV's Bartz and his acrophobia.
Final Fantasy X is the first, and to the best of my knowledge, only Final Fantasy game to have weapons that are truly detrimental when equipped (Celestial Weapons with neither Sigil or Crest found)
FFXII has 45 Marks, 80 Rare Monsters, 7 optional Espers, Hell Wyrm, and Omega Mk XII, giving it quite a bit more optional bosses than FFX.

And don't forget the Excalipoor from FFV! That's the classic crap weapon that does nothing but handicap you with it's automatic 1 damage.

And even without the Sigil or Crests, the Celestial weapons still ignore defense, making them pretty good weapons even without any abilities and No AP.
