So I'm playing the game and while it's still fun a scary thought came through my head. With the popularity of the game, how long before we see multiple spin-offs for the game? I mean the gameplay can only be changed so much and it looks like we're nearing the peak of how the game's going to play. Remember how popular DDR was? Well what happened to that series? We got DDR Remix, DDR Disney, DDR Electric Boogaloo Edition, DDR Barbie's House Party, DDR RRoD, and so on.  We already got Rock the 80's on the PS2. Why do I get the feeling a Guitar Hero game with Jem or Barbie or Mickey is just around the corner?
