I really, really like the cast and the world in this game. I haven't been as attached to the world itself since Vesperia, but I continued wanting to know more and more as I played it, which is awesome.
Combat was enjoyable, armatizing and stuff and dancing around the battlefield with artes and the like. Kinda cool to do it open-world-like, though in cramped areas the camera kinda sucked
Game was pretty easy, in my opinion, too. Use what enemies are weak to and you can destroy stuff. Unless the AI sucks, which it does a lot in battle. I just played through on Normal, but rarely game over'd.
I don't care too much about difficulty, though. The only thing that really ticked me off was something near the end of the game that I won't talk about at all to save from potential accidental spoilers.
I thought the music was nice, especially in certain dungeons and certain battles and scenes. The voicework was enjoyable, too, and I think they all fit the characters.
I already knew he was going to be adorable from what we saw pre-release...but he was just too precious once I got the game that I just had to order the Kotobukiya of him figure after I beat the game x3
