Message boards from 2006 called, they wanted to hear us complain about having to wave our arms around.
In all seriousness though, I still think it's a perfectly fine idea in some regards, although if it was supposed to be the next evolution in gaming it certainly wasn't. Nintendo barely implements any noteworthy motion control in their own games, and considering they're supposed to be the leader of the whole movement that's probably not a good sign. I definitely enjoy motion controls for golf games, light gun shooters, and other similiar games where there is a clear advantage to having motion controls, but these aren't exactly the makings of greatness. Games that toss in "jerk the controls" moments are definitely annoying.
