The only review I've came across that I actually trust is this one. He's a private individual, not from some corporation/magazine/gaming site, etc. He knows both Japanese and English, and speaks English fluently, and he played through the entire game, and recorded himself doing so, and, according to him, the game is pretty fantastic.

I will play the game, and I am excited for it. I seriously doubt it will come anywhere near being my new favorite FF game, but so far everything I've heard and read leads me to believe that I'm going to enjoy the heck out of it.
