What might seems to be boring for the true gamer, can actually be fun for other audiences
Anyway if you're a casual gamer and like to play simple stuff that doesn't require a more complicated set of direction and buttons inputs, you could enjoy dancing a little.
As for the songs there aren't too many, but you're going to recognize most of them, because they're very popular. Also good variety for the different taste of music. The game brings you a total of 32 songs that you can play in a short version or the complete song.
The dancing part shouldn't be a problem, you only going to need the wiimote and pick the song you want taking in consideration the level of difficulty.
