StepMania
StepMania is a cross-platform rhythm video game and engine originally developed as a clone of Dance Dance Revolution, evolving into an extensible rhythm game engine supporting various rhythm-based game types. Its core gameplay involves scrolling arrows meeting stationary targets in time with the song's beat, scored by timing accuracy, letter grade, and numeric score. Highest performance yields AAA+, requiring flawless timing, mine avoidance, and full hold arrow completion; failure results in an E grade when the life gauge fully depletes. It runs on Windows, Linux, FreeBSD, macOS, and Xbox.
