I'm not sure what you're trying to get at here? Is this a request to add Just Dance 2019 to the vault? if so that goes in the request board.
all just dance games contain 1 - 4 players, as it is a dancing game.
this includes just dance 1, summer party, 2, greatest hits, 3, 4, kids, kids 2, 2014, kids 2014, 2015, 2016, 2017, 2019.
