A welcome (albeit hopefully never to re-appear in this specific manner) departure in formula from the first two sky games. The gameplay making you able to play as so many characters was really novel and the customization the gameplay allowed was satisfying (though this only would hit if you already liked it anyways).
But obviously this is a Trails game so the story is what is mainly important. I'd say that overall it is a fantastic way to wrap up so many aspects of the overarching story of the Sky trilogy with an admittedly weird and sometimes detrimental way of going about it, but since I like the fundamental story additions it gives a lot anyways I don't mind. Obviously the highlight of this game is Kevin though. His story is perfect and he's one of my favourite Trails characters and protagonists still.
