People who played FFXI remembers this, however I think it was the only player collector's item they actually distributed. Just throwing it out there as I would most likely buy a necklace like this if I had the chance (didn't have the money back then to) and would get really excited to see a collection to come back. Possibly do the same thing they did in XI where you got an in game item (it was a body piece that would teleport you to Jeuno if I remember correctly).
