This is my personal opinion only: the battle system is awesome, the music is so-so (except for one battle music that is very, very catchy), the story and its pacing are aggravating, and the cast is worse than Vesperia.
Same here, except I like the story. Well, and the music is above average.
I would go for it. You will probably like it if you liked Vesperia and if somehow you find the cast unbearable or something you can send it back to Gamefly without buying. If you don't buy it I don't know how hard this will be to find when you clear out your backlog and take a second look.
