Pros:
* Possibly the best weapon customization, level-up system in any game I played
* Great Turn-Based Battle System
* Great Story
* Filled with content
Cons:
* Characters are okay, but they don't compare to some earlier FF games (FF6 and 9 come to mind)
* Soundtracks could have been better
* Voice acting isn't very convincing
* Characters don't move and behave very realistically. It's hard to put it into words but the game needed better directing
This summarizes my take on it.
