I completely agree, The Fall of the Lucavi/Scions, The Dynast-King, The Great Collapse, St. Ajora, Mullenkamp, and many more. There are so many events I want to learn more about Ivalice. Even more information on just the larger part of the world would be nice. You really get a greater sense of history from Ivalice than other FF worlds.

Reading the background info on Ivalice through the Bestiary in XII or the Dispatch mission in FFT you get a glimpse of something truly grand. What I wouldn't give for a Vagrant Story 2
