Not sure if this was posted. I know there are some Prime fans here (and I'm one of them), and IGN has put up a video of the demo walkthrough available at the press events. http://media.wii.ign.com/media/748/748547/vids_1.html Looks great. There are supposedly a range of control schemes, including an 'expert' mode that mimicks PC FPS games and according to IGN, works almost perfectly. Really looking forward to this.
Not so much mimics as it is just a super fast sensitivity speed and purdy blur. Still, you don't hear me complaining.
