I've never been a massive FF fan, but I must say I am enjoying this one. I'm in love with the new battle system, it's reminiscent of the battle system in Panzer Dragoon Saga, it gives the game a bit of a fresh feel from the previous ones.
I also welcome back the grid system similar to that of FFX. Don't worry, you still get EXP, it's just given a fancy name so it shows now as CP.
I don't get much time to play it so I haven't had the chance to open it up fully yet, but it's a thumbs up from me
