It used to run smoothly. Now its unplayable after a minute because of how choppy it gets. On Xbox one. I don't know about slim but on my current update box one Just dance 2015 is unplayable after 5 minutes due to how choppy it gets. Also I don't care for mashups, I like multiplayer. Also I don't think I'm the only one with chop. There used to be 10 to 20 players now there's 3.
