I'm playing the CBT for this right now and it's really good. The turn based combat is traditional but satisfying, The character designs are all top notch at all rarities, and the leveling system is fair so far. The story is pretty heafty but still good from what I've read so far. It's JP only so far, but perhaps if they do enough marketing it might have a chance of getting published outside of Japan later. We'll see I suppose.
