You can rename GFs, but you can't rename actual party members.
As for Vincent's limit break, I'm not counting it cause its a special mode. Gau doesn't have the actual Fight command on his menu screen when his turn comes up, whereas Vincent does normally.
223. FFVI is the last console FF that allows you to have weapons placed in either hand normally. Later installments either don't have normal equipment set-ups, don't specify which hand the weapon is used on, or everyone is right handed by default.
224. Kefka's "God of Magic" form is the first final boss form of a villain that was ever featured in a full CGI, in the Anthology edition.
225. If you look closely at the opening and ending FMVs of the Anthology game, Terra rides a different model of Magitek Armor than Biggs and Wedge.

226. VI is the only FF from the 16-bit era that doesn't have a sequel.
227. Despite wielding a staff in game, Banon's official artwork has him using a sword.
