Another one of Namco's typically overlooked RPGs. This is by the same development team as Tales of Symphonia.
The most noticeable change for me from Symphonia is that multiplayer battles are far more playable. The camera will zoom out a lot more when human players are attacking different targets. The free-run option is also useful, but it is not quite as easy to get behind an enemy, since the the enemy tends to try to face you, unless another character is hammering away at the enemy.
The battle system is much like Symphonia's, but the Fields of Fonon system is tricky to use and not reliable in my opinion.
I find battles generally harder than in Symphonia on the normal setting. There are a lot more close calls in boss battles. Money is a pain to get, as usual, but you get an item to boost money acquired by 50% fairly early on.
You can partially customize your character's stat growth, which is helpful.
The voice acting is excellent, and some Symphonia actors make a return.
The plot opens up slowly for the first 6-10 hours (depending how fast you move), but the gravity of the situation becomes very apparent after this.
