I don't know... the game certainly lack major factors to make it standout among the growing lists of RPG titles out there. This game unfortunately did not live to my expectations and standards... that's why i didn't finish the game.
The battle system maybe something new but it bored me in great depth, hardly appreciated by how movements are executed. Graphix is tittaly mediocre and just not right especially for a PS2 hardware, i mean they could've done better and with much details.
I would recommend you not to prioritize this game 'cause it is dull.
