Personally, while I of course prefer Chrono over Final Fantasy, I must admit I'm getting more and more curious about this Final Fantasy XI. It's reminiscent of FFIII, an episode which I always loved because its atmosphere is very poetic and fascinating (despite the NES poor graphics or the remake SD style). FFXI's story was written by Masato Kato also, this is kind of intriguing. I'd never bother playing the game, but I'm still curious about its deep storyline. From the little I know, the Zilaart people are basically the equivalent of the Zeal Enlightened Ones.
In fact, I think it's kind of a shame that FFXI is an MMORPG. With such an atmosphere and story, it would probably have made a great offline game... and a shorter project for Tanaka's team.
