I missed out on FF7 when I first got my Playstation, because it confused me (I was just a young boy). I traded it in for... brace yourself... Cool Boarders 2!
FF8 is the best, the only one I finished!
I never finshed FF9, because I got stuck at Gismoluke's Grotto (pardon my spelling). My disk broke soon after.
No PS2 for FF10.
