For a psp game it's exceptional, graphics are very nice and they have packed so much into it.
I would recommend doing a full data install before playing the game, if you're impatient like me the load times go so much faster.
I have been playing this game since the release, and when I thought I completed the game, I was wrong, it throws more and more at you, I just love it!
my personal opinion is that is a continuation of final fantasy one, but obviously mixed in with all games up to number twelve.
the art book, mini cd, everything that comes with it is a very nice bonus, worth the extra money!
In all I just think it's brilliant, I've been playing non stop since release and there's still so much I have to get through, probably the best psp game up to date, I can guarantee it will not let you down!
