A big step up from Final Fantasy XIII, which was pretty good. This is a very good JRPG, with plenty of stuff in it for both hardcore JRPG fans and regular gamers.
The Good: Frequent levelling up, nice monster capture system, good and easy to use combat, awesome graphics.
The Bad: VERY Cheesy music throughout, have to have the patience of a really patient saint to do all of the puzles (I gave up after a while), the moogle character is annoying... very annoying.
Definitely worth getting, a really enjoyable game and with HOURS of stuff to do. But you will get bored of doing puzzles (especially the ****ing clock ones) and getting all the fragments is probably a task reserved for the most hardcore RPG fan... who doesn't have a job or a wife.
