Thanks for the information.

cool, you got this from gamefaqs.com awesome, i wonder i should get this game now.

Not the exact wording actually. Might be from somewhere else.

It's courtesy of IGN FAQs, not GameFAQs .

well atleast this game is on ps2, so the grapics are a bit better, but i still think they should have made it into an rpg.
