I finished the main story earlier today and let me tell you, what started as a decentish story in 2.0 built towards something cool by the end of the 1-50 arc just to get absolutely awesome by the end of 2.55.

I never thought I'd play an MMORPG with such well presented and most importantly easily accessible even for casual players like me story. My only complaint about the story presentation is that I believe all of it should be voiced and the English voice acting is a bit so so at times, though recently it's gotten better.

This is hands down one of the better stories out there and definitely one of the best FF stories. It's a story that is not afraid to deal with death, political tensions between countries and inner conflicts between allied nations, it's an amazingly written and presented story with a much more serious and mature tone than say, FF13 series was for example which I did enjoy but the story was all over the place.
