As a series FF player, I really can't recommend this game.
There are four, and only four, good things I can say about the game.
1. the graphics, they are eye-poppingly impressive, best I have ever seen
2. specific parts of the battle system, namely: the paradigm shifting and the chain/stagger bar
3. the way battles are started, the whole mechanic, is good
4. sazh
Everything else was mediocre to bad.
An random example picked from the rather extensive pile would be, hmm, characters. 6 party members. The rest of the world, the huge scale of it which is impressive in a way the graphics really show off, is populated by 12 other characters, most of whom are just faces with a name, and you don't meet most of them. (might be 1 or 2 more, but it took me 15 mins to think of all these, and I really pushed myself)
If you've never played FF before then it's not so bad, you don't know what you're missing.
