What I would want from each FF.

FF4: Edward outfit, in fact a Bard job like Edward. Adult Rydia Hair for Ladies, as well as her outfit.
FF5: Nothing? Maybe Faris as a NPC...she's cool.
FF6: Celes Amano Outfit, hated all Male Characters here...
FF7: Aerith Hair and Outfit, Cloud's outfit is already here >.< Cait Sith and his Moogle should be NPC in GS...and where where where is Round Square?!! I want to go on a gondola ride
FF8: I'd love an FF8 raid tbf, like Crystal Tower was from FF3. Seed outfits, and hairstyles (one of the more realistic FF's)
FF9: Zidane Outfit is now a sub reward so that's covered, woulda loved a Vivi one, it's quite gender neutral.
FF10: Braids for our hair! In fact hair decorations full stop.
FF13: EVERYTHING.
FF13-2: EVERYTHING.
Lightning Returns: EVERYTHING.
Type 0: Uniforms please, and a job which plays like Seven...debuffing whip based mid/melee hybrid with ENDLESS combos...she was great.

Totally not biased to the trilogy :/
