And it used to be popular opinion that disease was caused by evil spirits. what's your point?
FFXI was for hardcore gamers if by hard core you mean people like I used to be, no responsibilities and plenty of time (or really procrastinating on something I should have been doing, like my school work at the time, good golly I wonder what my GPA would have been if the scales had fallen from my eyes earlier) to sit around and stare at a screen hoping, oh hoping so hard, that you would be the ones to kill a particular HNM, that spawns once a week and you've had someone sitting there babysitting that spot the whole time, the strategy for which was soooo complex, Keep tank alive, beat on it till its HP reaches 0, just like every other MMO.
Like I said, it wasn't hardcore, sure it sucked the life from your bones and gave an illusion of depth, but in reality it was a tank and spank grind fest with time sinks in masquerading as content.
