I only watched while my brother played the whole series... that's why I can't get over it. He'll only let me play up to that part where you get Ifrit in FF8 but won't let me use up a slot on his memory card (n years ago = kid = broke = no memory card).
But I do know quite a lot (how to get GFs, how to beat Ultimecia, the soundtrack for which city/boss, etc) for someone who didn't actually 'play'. =)
Although sadly it is impossible to get my hands on a copy of final fantasy 7.
Shame about that FF7. Most fans would say that it's one of the best in the series...
