Personally, I think, after analyzing the story of this game. There were a lot of open holes in the story. I don't think this was a game about story so much as it was a game about character and the development of that character.

When you kill the Pulse Fal'Cie, I didn't understand how that was possible. Barthandalus had said that Sanctum l'Cie could not harm Sanctum Fal'Cie; so then, how was the party of Pulse l'Cie able to kill the Pulse Fal'Cie in the tower... I dunno. I just think the story over-all didn't really make much sense. I just appreciated the development of the characters over time.
