I've never played any of the '20XX' Just Dance games before, but I was not impressed with the 2020. The choreography was overly simple, unless if you earned the extreme version. The issue with the extreme versions is that you had to get a super star on the simpler version of the song. I would hardly move my arms and get perfects on each dance move. A lot of the choreography also did not really seem to fit the songs too well. I do have to say the choreography was also too repetitive.
The music selection was extremely limited and overall not great. There were some really good songs on there, but I didn't want to play them due to the poor choreography.
I will say the graphics/song design for the backgrounds and stages were fairly good.
I really wanted to like this game, as I have played other Just Dance games before, but this seemed subpar at best.
