I seriously do not know why this stupid debate between these two games came into play DDR and Frequency are both fun games to play and I do not think one game exceeds another.
Frequency only has one thing against it. The gameplay of this game limits the user base. Not everybody can enjoy it. DDR, on the other hand, is a game that anybody, I mean everybody, can play. DDR is all about trying to master the steps, and not about the music. This is where the confusion starts. Frequency is about the music. Why do people play Max 300 or Legend of Maxx? Not because of the music, but because of the steps involved.
DDR and Frequency are entirely two different games. Just like one of the comments here. You cannot compare masturbation to sex......its two different things. If masturbation involved a woman, then maybe you can compare it, but as it stands you cannot.
End of discussion.
