Yeah, so Ubisoft is milking its dancing game franchise. Activision did the same with Guitar Hero until the market for it got bled dry. And as far as I know, Activision has no dancing games, so how is Ubisoft stealing their thunder? Because dancing games have overtaken instrument-based games in popularity? Because of the aforementioned franchise milking, releasing minor updates at full price every few months or so?
I'm not really sure what point you're trying to make.
