Racketboy has a great article about getting started with Dance Dance Revolution at home. DDR is still kind of going in U.S. gameplaces from the 2016 release of “Dance Dance Revolution A,” but hasn’t received a home release in that country since the days of the Wii, in 2011. That leaves options to picking up a home machine, finding a version for an older console, or, of course, yarr. Thanks, Konami! Your attention to preventing access to your products is ridiculous and easily mocked!
The ultimate decision reached is to play DDR Max or Extreme 2 on a Playstation 2, and on a CRT if at all possible, but the article contains a number of options that may be more workable for you. Dance on!
