Their fanfic archive is a bit of a grab bag right now-- not much selection, and for some reason the admin of the place posted a not-stellar-piece as her main offering -- but the discussions tend to be cogently-written.

I'm having fun with a thread in the Mythology forum right now discussing the possibility of a mysticism strain within the Yevon religion, like the gnostic, kabbalistic, and Sufi traditions within Christianity, Judaism, and Islam.

But bottle_of_shine is right. The web is littered with hundreds of final fantasy forums, all of them suffering from lack of members, and the more active ones tend to be occupied by jackass bastards and braindead twits. I visited and quickly grew inactive on a whole slew of those about the time I found this LJ Borg Collective.

FF_project is so small that it hasn't attracted jackasses, except for one recent drop-in from a mostly-harmless munchkin Aurikku fangirl. I think what makes FF_project nice is that its fans tend to be general fans of Final Fantasy's worlds and cultures and myths, more than obsessive fans of ships or specific characters (mea culpa!) so it generates a slightly different set of topics.
