With DDR being such a big hit in Japan, they decided to make a few spinoffs featuring music by specific bands and give them the "Dancing Stage" name. This is an experimental release, with some ideas showing up in later games (speed modifiers, a modifier menu, a difficulty beyond Maniac), and a few that didn't (different looking arrows on each difficulty which were kind of hard to read, difficulty ratings with decimals). I wasn't particularly a fan of the music outside of mild interest that there's a 90's J-Pop version of Toto's Africa, and it just led to some awkward charts. But hey, it gave us Sexy Planet and Celebrate Nite!
