If you have played Samba de Amigo in the past or plan to play past normal difficulty, do not buy this game. The controls are fine when it comes to your right hand covering the right side and the left with the left, but when you need to get into doubling up on one side, the entire game falls apart. Even the dance bits are completely broken. And even though the game passes as playable in the earlier difficulty levels, you will still need to play in a very robotic way to get it to register...don't expect to get into the groove playing this. Oh, and I was even playing with two Wii remotes, so presumably it could even get worse if you play with the nunchuck.
One part unreliable Nintendo hardware + one part shitty new Sega game = total disaster.
Still, the soundtrack is pretty good, but I don't get why Going the Distance is listed under 'Theme of Rocky'.
