I go to Zumba regularly at my gym, so was keen to try this game. To be honest I wasn't overkeen with Wii Zumba 1. I found the dancer routines quite hard to follow and the graphics were poor. No such problems with Zumba 2! What a fantastic game!!! The graphics are far superior. The lead dancer (who you follow) is one of the Zumba team (from Zumba dvd) and the dancer changes with every song. There are also back-up dancers in the background, making it much easier to follow. Also there is a little circle at the top of the screen, which shows you the next dance move.
Once you have loaded your profile, you have a choice of dancing to:
'Single song' 'Full class' 'Learn the steps' 'Progress tracker'.
I have just done the 'full class' section. Within this section, you have a choice of a short class, mid , full length or a custom playlist (where you can choose your songs). You can also choose your intensity level.
When you have finished your class, it tells you how well your technique was, how many calories you have burnt, and your score. As you progress through the game, you are given trophies, which are added to your progress tracker.
My only 2 small critisisms of the class section, is that it doesn't tell you how long each class is. There is no clock either, so you have no idea, how long you have been dancing for and how long you have left. I did the mid length class on mid intensity and it lasted 50 minutes. Also, I sometimes find my Wii remote falls out of the Wii pouch, especially with the more energetic dances.
So, in conclusion, apart from 2 small details, I think this game is excellent and is about the closest you will get to a real life class.
