StepMania is a cross-platform rhythm video game and engine. It was originally developed as a simulator of Konami's arcade game series Dance Dance Revolution, and has since evolved into an extensible rhythm game engine capable of supporting a variety of rhythm-based game types. It can be played with a variety of peripherals, most commonly dance mats or 'pads'. Several video game series, including In the Groove and Pump It Up Pro use StepMania as their game engine.
