Almost done with the game, and I gotta say...
Don't get it.
Story: The characters, both the good and the bad, are very forgettable and the player will find almost no incentive to pay attention to the story (which is completely boring). I really really didn't care about what was going on 80% of the time.
Design: Gone are your shops and towns, replaced by a small floating device that does all the weapon selling and upgrading, level saving for you. I personally didn't even care about what weapons I used (which is weird because I'm usually very obsessed with that sort of deal).
Gameplay: Battle system is impressive, but it gets so monotuous. Eventually, once you get grinding going, all you really need to do is press X and L1 at times.
Graphics--Good, but Uncharted 2, God of War 3, and Killzone 2 look just as impressive if not better. Graphics will always improve in the future anyways and is probably one of the most overhyped thing about gaming right now. Look at Mario Galaxy 2. I WANT that game because of witty level design and perfected gameplay. But yeah, no doubt about it. Final Fantasy XIII has good graphics.
Voices: Lightning and Sahz do an impressive job English voice work, Fang and Hope are alright as well (but Hope is awkward). Snow reminds me of the typical dumb anime protagonist, and Vanillle.........will Piss You Off!
Probably one of the worst games I ever bought to be perfectly honest. I've invested a lot of time already into that game and plan to finish it, but I must warn you. Don't bother with this one. Wait for Vs. XIII or Persona 5 or a Tales game. probably better.
