It’s true. You can be really into just dance and move around and make a fool of yourself (YouTube gold!) or, you can (like my brother) sit on the chair and absolutely dominate the score with some simple flicks of the wrist. That is because it only measures the accelerometer in the controller which is easy to fool. My favourite is how it lets you use your cellphone instead of the controller if you want, which just seems like a genuinely bad idea.
