Now, I played Brain Age yesterday for the first time in awhile, and Dr. Kawashima's head pretended not to know who I was. That hurt. But I do think Wii Fit is something I would use with regularity. I managed to keep up with EyeToy: Kinetic for about two solid months, and that thing simply didn't work: I had to light myself up like a Christmas tree for the camera to see me (every light on in the living room, plus three halogen lamps pointed directly at me), kept bumping into the ceiling fan because I needed every inch of the room to play, and still the camera missed half my gestures, so I always got bad scores. And most of the non-aerobic exercises were just a glorified fitness video, offering no feedback. So what I noticed most in this early evaluation of Wii Fit was a lack of comments about things not working. So I am very excited about this product. If only they could pull off a holiday release, but given their now-baffling inability, eight months in, to make enough Wiis, I'm relatively sure Nintendo couldn't pull that off.
