I played the demo and I liked it other than that stupid jerking motion required to yank souls from enemies.
For some reason (possibly because you have to grip the controller with two hands), the upward jerking motion with the SixAxis isn't nearly as accurate as it is with the Wii (ba dum bum).
I have no problems with motion controls whatsoever but I do have problems with inaccurate motion controls (side-to-side/front-to-back works wonderfully on Sixaxis but sudden motions don't seem nearly as reliable). The reason I don't think it's my mental retardation is because I've noticed it in three games now (HS, Lair, FL) and another longterm gamer who I write with has had the exact same complaints about sudden motion with the Sixaxis. Neither one of us had any problems steering AfterTouch in HS or steering a dragon in Lair (not considering the immense lag in that shitbox of a game).
Anyway, I hope to have a full review of this game early next week. Damn, my plate is full. Phantom Hourglass, Orange Box, now FolkLore... Ugh.
