Mini Games from Final Fantasy past the could/should make it into FFXIV
Final Fantasy V: Piano - Confirmed :) :) :) Kinda ;P
FFXIV Implementation - Simple really, place a piano in Adventure Halls and allow player to sit down and play it. 1-9 would be different notes

Final Fantasy VII: Gold Saucer - Confirmed :) :) :)
FFXIV Implementation - Already hinted at by Yoshi-P

FFXIV Implementation - Run around on a Chocobo digging for buried goods with a warmer / colder game
FFX: Blitz Ball
FFXIV Implementation: Perfect for PvP players that want teamwork and objective base content
