The first player is prompted to come up with a move, which is to say any move. These don't have to be pulled from Dance Central's (admittedly extensive) catalog. You can literally do anything you want, so long as it matches the beat and you can successfully repeat it a few times. Once Dance Central 3 recognizes the move, it will attach an appropriate cue card to it and even give it a name. Once the move is stored, the other player has to replicate it.

Once both players have come up with a few moves, Dance Central 3

Dance Central 3
busts a move this fall.
