I've been wondering for a while now, during co-star mode, does the 2nd player need a nunchuk ASWELL as a wii remote? Or just a wii remote?
Nope, no nunchuk. Just an extra little pointer and added jump. If you're playing as the Luma in Galaxy 2, you can annoy the player using Mario by grabbing a 1-Up Mushroom and than not giving it to them.
That is what my brother does.I did that a lot. And then when one of my friends was the Luma, we were in a level where one part involved waiting for a boulder or something to roll past and he just held it in place and never let go.
