X was easily the last great single player Final Fantasy. But I dare say you have missed out on the far better ones earlier in the series ; VI, VII VIII ...

Being immersed in an MMO is not really the same thing as being immersed in a single player game where you control the main characters. YOU are not in any of the single player games, it's like watching an interactive movie unfold. In FF Online you get to make your own character but because you're not the only one they try to make the story make sense for everyone together. Hence why we are the helpers of the greater heroes and not the heroes themselves. In my opinion this makes sense.

Yes Bliztball or something similar would be very cool.
