Mmmmm. Even with the Nunchuk, there simply aren't enough buttons for a game like Brawl. In fact, you'd have more flexibility with the sideways remote by itself... And motion sensitivity isn't really fitting for the fast-paced Super Smash Bros. series... perhaps it will come with a coupon to save on a Classic Controller or something. Sucks to be whoever buys it without a controller with which to play. I'm on the other side of this--if you need to use a remote to play, then I'll have to buy more, and I don't want to until more colors are introduced (I don't really know why, I like it that way), and the price tag isn't very appealing. I have enough GameCube controllers for four players already, despite the fact that one's buttons are sticky and one is third-party, aka broken-like. If and when I fix this one WaveBird, I'll have three of them (that is, WaveBirds), and I plan to buy a fourth one and laugh in the face of cords. In this scenario, Brawl being GC-controller-controlled is... awesome.
...Related to the topic, could I get a cheese launcher too?
