Finally, a party game that actually is one.
The sound quality is very good. The graphics are nice and clear. Your player dances on screen as two images next to you show what you should be doing. You get told how well you did. Don't be discouraged if it takes time to pick up some of the moves. You'll get used to the mirror images. Just relax and enjoy the songs, and there are lots of good ones from which to choose. I appreciated that the selection had some album tracks and different things, alongside the big singles. You're not going to get bored.
The higher the difficulty of each song, the better the workout you get; it's good fitness in addition to the musical aspect. Make sure you have a clear space, because you will need to move over a good area.
Get ready for a fun game.
