The art is just so damn classy.
This one, in particularly...:
I think I've said it before, but I'd kill for a FF game to be set in a sort of fantastical steampunk noir setting. Have fantasy aspects(magic, dragons, "kingdoms with crystals", summons), but also have a world with a setting that takes HEAVY inspiration from the 1900s-1940s. Have the main character some sort of hard boiled detective with a new type of gunblade, have him protect a flapper girl that also has strong magical abilities, while trying to stop steampunk cyborg gangsters and a Kaiser-helmed invaders piloting smoke belching iron golems.
