サンバ・デ・アミーゴ（新）

The maraca controller setup is so intuitive that my grandmother was playing within two minutes. This is hands-down the most joyful party game I've ever owned for the Dreamcast.

Plugged in the maracas and my sister, who hasn't held a controller since the 90s, was hooked for two hours straight. The motion controls actually track your shakes well, which makes even terrible players look like they're performing.

My friends who never touch video games were fighting over the maracas within ten minutes. The motion controls are forgiving enough that anyone can jump in, and the song list keeps the whole room playing for hours.
