Maybe I just imagined this, I can't remember, but I thought the Wii warns you when your Remote's batteries are low? I thought this happened to me while playing Twilight Princess, but I honestly don't remember.
It most definitely does.
Anyway yeah this controller thing is pretty lame. I don't think I'd mind using the Wii controller+chuck if they made the controls OK. I'm sure I'd get used to it.
Even if they went with Wii controller on its side, or the classic controller attachment. Hmph.
Guess I'd better get another cheap GC controller.
