What changes/improvements would you like to see

[Sephiroth]

I'd like to see a black female character used as a playable character. The only black female I've seen the entire series has been Dona, and she wasn't playable.

Fran is dark skinned. Or do you mean a human character?

Hell, I'd pay to see them create a black protagonist or even antagonist.

Then you have to look at Kingdom Hearts with its black-orange skinned antagonist. But of course it is not really a "Final Fantasy".

Also, I'd like to see them make an older woman in the playable character cast who's NOT in her teens or twenties. Say, thirties to fifties. It's like the Japs are obsessed with young girls and women only.

Well - there I mention Fran, but because she is a Viera she still looks young and I think that's what matters for you.
