i played some of it on the jap version, till my ps2 started being like a rental machine, and only letting me play burnt dvd+rs once, and then not seeing the dvd after that.
I think it felt well corny at the start, something not akin to FFX
but as a seperate game i think it is well done
Try to think of it as not a final fantasy , then you can play it without fearing a change in the style of the series.
