Not a 7.5 in my opinion - more or less an upgraded FFX.
-Graphics: The game looks brilliant and the individual scenes and characters are artistically beautiful. I have not experienced any of the frame-rate problems described by the Gamespot review and I have *certainly* not experienced the long loading times they complain about - I have not had a loading time longer than a few seconds.
-Sounds: Great music, good voice acting (in English, at least).
-Story: The story focuses on immortals searching for memories of their past. If you're in it for the story (which is interesting), you're in for some reading - every time you learn something about your past, you have the option to read something about it. Don't worry though, you can get by without them and still experience a nice (though obviously predictable) story.
-Innovations: There's a ring system added to the combat that keeps you a bit more involved than mere turn-based fighting. There's also a skill-linking system that's really entertaining to mess with. (Don't worry, there's more, that's just all I put.)
-Overall: Great story, beautiful graphics, really entertaining, very immersive, neat little additions to the standard JRPG system make it great.
I'd recommend buying it, personally - renting it won't give you enough time to get through the good stuff (and the game takes a couple of hours before it actually gets good) - but if you don't like JRPGs or aren't sure about them, I'd, at least, say you should try it...
If you liked any Final Fantasy games, or anything like them, don't worry, you're sure to love this one.
