That's fair enough. A game can't be flawless, it's practically impossible. Just so long as the developers try to make it flawless.
On your last comment, I don't think Nintendo are going to ignore comfortable control schemes so the game can have more of a casual appeal. It would be illogical of Nintendo to do such a thing... if comfortability doesn't come first, especially in Nintendo's case, then the developer is screwed majorly. If you're referring to the creation of the Wii remote to appeal to casual gamers, I think that you're wrong in the sense that the motion sensing in the Wii remote can be done successfully and with a very high level of comfort. Maybe not as high as the precision of a mouse, but high enough.
