I haven't played FF IV since I got it for SNES and it's still burned in my mind. My whole family played that game. My dad played it and that's the only console game he has ever played. I can't remember why but I never played VI. Maybe because Mystic Quest was so bad (that, I remember). I think I remember also disliking sci-fi or steampunk which is maybe one of the reasons why I only ever watched other people playing the later games until FF XII (which is oddly enough more in line with FF 2 (IV) in the type of fantasy it is.
