DDR meaning in Community ?

Dance Dance Revolution (ダンスダンスレボリューション, Dansu Dansu Reboryūshon) (DDR), also known as Dancing Stage in earlier European games, is a music video game series produced by Konami. Introduced in Japan in 1998 as part of the Bemani series, and released in North America and Europe in 1999, Dance Dance Revolution is the pioneering series of the rhythm and dance genre in video games. Players stand on a "dance platform" or stage and hit colored arrows laid out in a cross with their feet to musical and visual cues. Players are judged by how well they time their dance to the patterns presented to them and are allowed to choose more music to play to if they receive a passing score.

Dance Dance Revolution has been met with critical acclaim for its originality and stamina in the video game market, as well as popularizing the use of videogames as a medium for fitness and exercise. There have been dozens of arcade-based releases across several countries and hundreds of home video game console releases, promoting a music library of original songs produced by Konami's in-house artists and an eclectic set of licensed music from many different genres. The game is also known for its passionate fanbase, as well as its growing competitive tournament scene. The DDR series has also inspired similar games such as Pump it Up by Andamiro and In the Groove by Roxor Games.

The series' current version is Dance Dance Revolution A20 Plus, released on July 1, 2020.
