9 was my favourite FF game, but don't want to replay as often for me the reality of game mechanics has moved on so much that the clunkiness of older games in retrospect robs you of the charm and good memory it left you with at the time.I realise that it's a very old game, but it didn't really "grab" me as much as I expected it to. I suspect that a lot people out there played it on the PS1 - indeed I did on a friend's PS when it was new, but only got a few hours into it. I did enjoy it back then, but gameplay has improved since then 7 feels pretty clunky now.
I'm working through 9 now and it's leaps and bounds better, in my opinion. I have played it in its entirety in the past though.
