I bought the Just Dance 2014 game and it entirely fails to function. The game requires the camera and while the camera works with full functionality in the playroom the game, it cannot detect players in Just Dance. The game will score randomly despite having no player present.
The game is falsely advertised and does not function with this hardware as indicated. I would avoid it and potentially all other multiplatforms using the camera until Sony begins taking quality assurance seriously and solves this issue.
The scarce reviews available for this version mention but gloss over the fact that the product does not work as advertised but fail to properly warn customers that they would be buying broken software.
