How is it one of the deepest stories in any FF? Jeez, FF1 almost has a deeper story. Really, you're presented with a story about 2 major warring nations and the struggle for your small nation in between it all to gain control of its own state again. Thing is, is that its all pushed into about 1 month of a time span. You see the part at the beginning, you see Vayne taking over power of Dalmasca then you start off on the journey.
There is no backstory for any of the nations, you have no real idea as to why the nations are warring, the reasons as to why the monsters are there are stupid, and there are massive plotholes. How the hell did Penelo and Vaan learn to fight? What does the senate Archadia of the do? Where did the Judges of Archadia come from? What sort of country is Rosaria, whose to say they aren't the 'bad' guys? Why isn't Dalmasca an actual ally of Rosaria? What are licenses, why exactly are they there? They tried to cram waaaay to much into this game, and attempting to deny this is useless.
I'm not saying that everything in a game should be explained to you, but I just could not get into this game because I had no rational reason as to why everything was and why it was happening. Square should leave these sort of games to people who can make them, and make them well.
