I've been playing it since yesterday and I have to say, To me this is without a doubt the best alternative Final Fantasy RPG ever made, If you've seen reviews pointing out the flaws in the game , Such as low frame rates and over the top animations. As far as I'm concerned, The low frame rates are forgiveable due to the excellent storyline, and the over the top animations are done in true Final Fantasy style, and to me they aren't over the top, they just add to how great the game seems to be put together.
Graphics are not quite as next gen as say Gears of War or certain other games, But they are definitely not Play station 2 standards, I'd say they are somewhere in between. (Hell I'd take playstation 2 graphics and a higher frame rate, game play all the way when RPG's are concerned)
Without giving away any storyline, I'll add that there is a side quest available from the start to the end of the game, that get's you to know the main character in GREAT detail, and it's a welcomed edition to the game, Infact I'm loving moving off the mainstoryline to trigger as many side quest missions as I can to learn more!
If you are a final fantasy fan, or an RPG fan, Go out and buy this game, It's for the 360, And for people who arent fans of Final Fantasy 12, The battle system in this has returned to turn based, like Final fantasy 7 through 10
For me so far, I rate this game an 8/10
Just so you can see how I rate the other Final Fantasies to compare
FF7 10/10
FF8 8/10
FF9 7/10
FF10 9/10
Have I pushed the game enough now?
