At times the game can be overwhelming and frustrating, that much is true, but the game manages to remain absorbing and addictive despite (and maybe because of) that. It's the type of game you'll pick up to play for twenty minutes while you wait at the doctor's office, only to immediately prefer dying of leprosy to actually putting the DS back down again.
That said, the game can't quite claim to be perfect because, as Bit-tech always says, when it comes to handing out a score of 10/10 they're usually looking for something innovative or new in a game. Order of Ecclesia doesn't offer that, despite the tweaks to the combat system and the new area-by-area navigation system.
It is an awesome game and if you've got a DS then you'd be doing yourself a huge injustice if you didn't pick it up, but it's still very much standing on the shoulders of those who came before. Excellent, but not exactly groundbreaking.
