I started playing FF when I was about 9, around the time IV came out, but for the longest time I just borrowed the game from my neighbors and would just mess around on their saves, rather than starting my own game. I kinda didn't get it. 9 seems rather old but maybe I wasn't that smart. I didn't actually really understand it and start my own game til I was maybe 11. One of my neighbors who is the same age as me played it and beat it though when he was around 9, so maybe I was just slow in catching on.
