Things that CAPCOM forgot to mention...
MHG requires a Classic controller to run. For customers who bought the Starter Pack, you will be just fine with the included Controller.
However, for those who bought only the game itself, please be informed that your Wii controller+Nunchuk DOES NOT work with this game. Only way to play it is to use a classic controller like Gamecube controllers or the one from the Starter Pack.
