> Dance for the computer, it will judge you

Those games are wildly popular!

In fact, being judged by the computer is a favorite way for many people to spend their time.

Which games are you referring to?

All the ones I've seen (Dance Dance Revolution, Dance Evolution and the like) aren't judged subjectively, but are objective. Your foot either stepped on the foot pad at the specified time or not. Your arms were either in the right spot at the right time or not. It doesn't "judge" anything.
