I remember I played the demo some odd weeks ago, and I had an "on the fence" feeling about the game, so I waited for the IGN review. Sure, the reviewer is a noob at IGN, but he really went in depth with this game in the written review, which is what I look for when I base a game purchase/rental/time on a review. I liked everything that was pointed out about the game.
I bought it just yesterday, and I must say the story is getting really really good. The actual gameplay so far isn't stellar because I just started it, but I'm sure it'll pickup within the next 15+hrs of the game. Do note that I'm not a fan of RPG's, especially not western RPG's, but this RPG is the best one I've played since FF7(still not as good as FF7, though, but what RPG is?). This game really emphasizes story of over gameplay, not to say that the gameplay isn't good.
I do like the way they implemented the sixaxis into the fighting too. You weaken the monsters, or folks, and take their souls by holding R1 and quickly poping the sixaxis upward. It kinda gets addictive after a while. I haven't gotten far in the game yet, but so far I'm more than pleased of it, so a 9.0 seems like a definite score to me. If you're still on the fence as I was when the demo came out, I'd strongly recommend renting it to clear any doubts. This game is what an RPG should be, and I really love it.
