The last time I played FFX was the North American PS2 version but when I started up this version of FFX, it asked which version of the sphere grid I wanted to use. Can anyone tell me what the differences between the two are? I'm assuming one is from the north american version and the other is from international but does one make the game harder than then the other? Are there abilities on one that aren't on the other? Kind of a shame they don't give you a short blurb on what the differences are when they ask you to make your choice.
