I did not like the 2015 version for the following reasons: - There is no indication either on the difficulty (1 to 3 cog wheels) or on physical exertion (1 to 3 drops) of each song, as it had in the previous version. Why? I miss terribly. - We are constantly interrupted - I would even say parasite - with proposals of all kinds, such as: Add challengers. It enerve. We could not dance alone? - The surcharges are Intefaces info and almost never with direct action 'C'est tres' huh' irritating (I stay polite). To explain what I mean: If we take the example of adding challengers when the interruption occurs, you can not just say no and continue! There are no direct refusal possible. We are obliged to go to the Add challenger interface, and only, then you can choose to get out! Grrrr ..... - As in previous versions, each chore was starting with some simple movements and repeated, to get "in the bath" before tackling more difficult later in the song. The chores had been thoughts One felt that good. In this version ca hand in every sense of the beginning, with little repetition and therefore little chance "to hang" departing. Okay, well for me it is totally demotivating. - In general way, everything is too much. The colors, the aggressiveness graphics, filling each interfaces maximum, as if it had been important not to leave an empty corner ... We take full eyes. Too much for my taste. It was a feeling of general mess. In the end, my impression is that this version, the game was essentially oriented towards younger, for use in the evenings, in groups, with the "online" at all costs. So if you are like me and you use this game rather for the pleasure of dancing alone at home, stay in preceding versions. It's me that even I have done, by returning to the 2013 version, which remains my preferred over date. A star so for this version 2015, which I find disastrous. Note FYI: It turns out that I was both a Wii and a PS4 at home. I find the Wii version of this game much more pleasant to use than the PS4 release.
