Honest? This looks pretty lame, the sound design is terrible, and much less does not look fun to play. I am not saying the animation is bad, and that I wouldn't play it because of that, (it's not good either) I am just saying that this doesn't look fun to play.
I have the X-Box version and love it. If they add some cool on-line or quasi-system link add-ons, I'd pick it up.
I'm worried about this because it's a PS2 port and after the mess of Rygar (the last PS2 port we had) I was concerned, however, this looks pretty good in the video - all depends on the gameplay though.
