I was disappointed when I realized you could not transfer songs from Zumba fitness rush to the core. Why not? The game play is good. Tracking does what it is supposed to. New songs and choreography to change things up. Community? What you now have leader boards? That about it folks. Not much to do there. Its is not supported by connect play fit? Why not? Until they come up with a way to compete live online and do workouts with someone online this is always going to be another workout video. Lots of possibilities but no one a majestco is paying attention. Go figure.
