A solid installment on the Just Dance series in terms of the songs, challenges, scoring, and accuracy of rating the moves. I'll save the song listings, etc. for users who have already posted them.
Having said that, however, the hand pointer (and I'm used to no controller so I'm not one of the, as a user put it "old folks" learning to switch from controller to hand navigation) is inaccurate. It took me nine minutes to get the hand to press start--finally backed up, lunged forward pointing, and hopped back.
Once you get over that, the game is much less frustrating. For those who have tried Just Dance 2013 first, you'll notice a different variety of dancers (and body types), and a wider variety of dance styles than on Just Dance 2013, so I tend to actually like this version more.
I've played Just Dance and it's great. The songs are really good. My favorites are Moves Like Jagger by Maroon 5, Rock and Roll by Skrillex and Good Feeling. The best parts about the game are the mashups, extreme versions, battle modes and normal dances. The only thing I dislike about it is that you need Wi-Fi for some songs. I'm looking forward to Just Dance 2014.
