(This should apply to any game other than the original Just Dance, but I'm asking about Just Dance 3 if you need something specifically.)
I see a lot of videos with people getting all Perfects. However, I never see two people get all Perfects in the same video.
Let's say Alice and Bob play and they get the exact same ratings for moves. (For example, every time Alice gets an OK, Bob does too.)
What happens then? Does the game not "crown" a winner? Or is there something else that happens?
