Kairon, I don't know...Nintendo definitely didn't put as much into it as they would like us to believe, but I definitely think there is room for improvement.
The one thing that bothers me is that Nintendo's main purpose for the wiimote was to create easy, pick up and play experiences, and that was touted as being a major ace by Nintendo fans. And yet, so far, most games have proven to be anything but. Every mediocre/bad review of a Wii game that I've read usually spends a good deal of time criticizing the controls. And the usual response to that is "well, obviously these guys suck and didn't take the time to learn the controls." But, if it's true that most reviews don't get written until the reviewer plays through all or most of the game...if they didn't pick up the controls by then...well doesn't that still mean that wiimote isn't fulfilling its pick up and play purpose, whether or not the reviewer sucks? Heck, my friends and family all love Wii Bowling, by far the most played game on my Wii. And STILL after all this time I get that dumb "oops" message more often than I'd like, and more than once members of my family have put down the controller in frustration.
I still believe that the controller is capable of more, but one thing I said on these boards before the Wii was released was that, after playing the Wii at the Fusion Tour, I didn't think the wiimote was going to be any easier to use than a regular controller. It was going to be difficult in it's own way. So far I seem to be right.
