I won't say this isn't a great game. I won't say it's not enjoyable.
The only weak points in this game are the plot and the soundtrack. It's so childish, you can tell everything that will happen before the character will even know they're alive.
The battle system is great, finally some action in a jrpg, the graphics are pretty cool (I love cel shading) and i like the charades.
The music is awful, too. I mean, there isn't a single track worth listening that you can remember after 3 minutes. It's a shame, since it's also a pretty long jrpg.
However, I liked this a lot expecially for the battle system. Don't expect Xenogears-like plots, though.
