I'd like to be able to play a kid character

Been saying they should do this for a long time, but it will never happen because of all the alcohol and sexual references. There are a lot of underage characters in offline Final Fantasies though. I'd actually challenge someone to name more than 5 FF protagonists that were known to be older than 21.

Technically, we should be going by 20 as that's the age of majority in Japan...although you are still correct.

Firion - 18
Luneth - 14
Cecil - 20
Bartz - 20
Terra - 18
Cloud - 21
Squall - 17
Zidane - 16
Tidus - 17
Vaan - 17
Lightning - 21

Only 4 of the main protaganists across the released mainstream games are off-age in Japan. And then you have Luneth...14, really?

And then you have Lightning who finishes her story aged 521 years old...
