Played the game for a little over an hour. Battle system is definitely boss. The cinematics at the start of the game were a little exhausting to be perfectly honest. The purple hair pig tail girl totally gave me flashbacks of Arc Rise Fantasia's intro (I know, I know, this is better written/voiced, etc.). Still, amnesia mystery girl is not really my preferred way to start an RPG. Maybe I've just grown too far from Tales games? I don't know.
The two brothers are kind of neat, I could see the two growing apart from each other as they get older. Maybe Hubert does some questionable things later? That would be cool. I'm thinking I'll start feeling the plot more once I'm out of the child arc, but at the moment it is all about the gameplay, which isn't a bad thing. I think the only RPG I've dug with a child arc was Breath of Fire II & III.
Oh, and the battle track for the kids is total Motoi-stock. Hopefully, there are other, better battle tracks?
