Only play FFX-2 if you like Jpop and chick flicks. If you play RPGs for graphics then you need to be shot. Chrono Trigger is 100× better than any new RPG.

Crisis Core ---> (the story continues right away, like the very next thing) Final Fantasy 7 ---> Advent Child (2 years later) ---> Dirge of Ceberus (i think 1 year later after ADV CHILD)

Voouch i think it goes in that order particuly
