There's pretty much one way i could be compelled to buy a 3rd party wiimote, and that's if they made little kidney shaped (or in this case, L shaped) 1 & 2 buttons to go right next to the A button, as well as where they are currently
Certainly in games like Metroid Prime 3, i could totally use the map button next to them
Monster Hunter: pissing me off since 2010.
