I'm 9 hours in preordered it from buy.com when they had a $10 off preorder sale.
The story was boring the first 5 hours then it started to pick up. About 7-8 hours in it became interesting. Make sure to change your battle setting so that you control your fights. The tutorials are pretty bad at teaching the mechanics. The battle system is pretty fun once you get the hang of it, but there is a lot of slowdown when there are a ton on enemies on screen.
They upgrade system for the weapons is cool, and since you can grind for more money, you should never worry about not spending money as you get it. The camera is by far the worst part of the game. Not as bad as older games, but I had to fight one of the bosses like ten times, because the camera was causing me so much trouble when I was trying to figure out the weakness of the boss.
I would say so far despite the problems get it. The game is very fun once the main elements are introduced. Also, you don't need to grind, but I enjoy doing it.
