well graphics wise, its locked at 30 fps, zero actual changes you can make regarding anything (AA and shadows and that's it) and it only supports 720 and 1080 resolutions. Not to mention the games cut scenes have random frame rate drops and look worse than the game because they weren't remodeled.
story wise, its set in the ff-13 universe so its just more evil empires and their L'cie or whatever causing trouble in goody two shoes town. the english voice acting has less emotion than keanu reeves, and the models look like inanimate bricks half the time you see them up close.
game-play wise it plays kind of similar to a dumbed down crisis core, you get 13 characters off the bat to pick each with their own set of stats that affect what magic they can use to compliment their weapon/ability. problem with having so many choices is a large chunk of them are totally worthless a few hours into the game because only your 3 active party members gain XP, and if you have the SP system on (causes random npcs to take over your other 2 party member slots, but gets you rarer item drops) then you will generally be stuck playing the game with a single main party while the rest sit on the sidelines being worthless. Most of the combat is generally dull as well, simply mashing dodge until the lock on reticle flickers red so you get an instant kill attack or just spamming thunder since every enemy is mechanical and since you only ever really have an attack button and magic button you generally just play one of the characters with a gun and run around doing that. Worst of all is the camera when locked on does not like to sit still with all the dodging you'll be doing and will flip and point every single way except the way to get the locked on enemy to appear on screen.
