One of the best games to date.
The story is amazing, possibly the best aspect of the game. The fighting is loads of fun and requires more strategy than other FF games since you can take the time to plan ahead using the turn meter on the right side of the screen.
Great variety of characters and great character development.
I've played it about 5-6 times and each time takes over 30 hours, and it could take you even more than 50 hours if you take the time to explore the great world of Spira and the many side quests it offers.
In a nutshell: highly recommended.
