A big part about Dance Factory is that you could add your own music by using your own CDs. But, the way the game charts the songs is horrible. The charts don't fit the overall feel of the song. Where you would expect to see a bunch the notes, there is hardly any, and where you expect to see hardly any notes there are lots. You could chart the song yourself, but the system is broken. All it does is playback the song and you press whatever button you want on the mat to chart the song. Do you want to edit the song? Too bad, because if you want to make any changes to your chart, you have to delete it all.
The visuals are boring and there no excitement to the game. It is fun for a day and gets old quickly. Save yourself some money and buy a different rhythm game.
