One thing to note is that it adds more questions then it actually answers, especially the ending, but that's just good for a mid-series game. Never answer to many questions at once and always make more, right? But other then that, it got a great story of it's own and it shows the past that was experienced by about half or your main characters.
I do like the revamp of the skills and customization of the character done for this game. It's a lot less confusing then the first. Plus, each character actually had it's own set of skills, it wasn't a poor rip-off of the FFX sphere grid system like the first one.
Anyway, I enjoyed playing this one far more then the first, though you always have to play a series in order.
