Definitely would love to see a thorough breakdown by age group as well as gender if there are enough submissions to support it.

Other interesting data would have been things like:

-first system you played games on (NES, SNES, PS1, DS, etc.)
-first FF game you played
-what age you were when you first played a FF game

I say this because people even in the same age groups can have vastly different gaming experiences that will color their opinion of various games and game features outside of their age alone. Myself, I was playing video games before there was such thing as an SNES, but there are certainly people my age who were never into games until somebody got them hooked on, say, FFVII.
