If the class system was a bit more interesting this would comfortably be a 5 star game for me. Unfortunately the classes just weren't very interesting to experiment with and only offered a small amount of value in skills that carried over to over classes. Necessary if you wanted a good variety of elemental attacks on your mages though or more than one or two damage types on your physical fighters.
Fantastic in every other regard, I completed every major minigame, substory and activity in the game and is one of only two games I ever wanted to start an immediate New Game + save in.
