But the Remote and Nunchuk just don't feel the same as the original maracas. Sega representatives mentioned that the company is still considering input device add-ons and alternatives; the game might even ship with a new maraca controller. (I wouldn't bet on it, but apparently, it's still a possibility.) Short of that, it might include some sort of rattling add-on, like the Wii Wheel of rhythm games.
I flailed and shook to a few Samba tracks from the game's more-than-40 options. Sega is including many from the Japan-only Samba 2K release as well as classics and new tunes. Mentioned music and musicians include "La Bamba," "Take On Me," "Santana," and "The Gypsy Kings." While any music game plays better with your favorite songs, Samba has been less about the tracks and more about the maracas. I was entertained, but I missed that rattle.
