EZ2DJ

EZ2DJ (known officially as EZ2AC after 2013, now known as EZ2ON) is a partially-discontinued series of Arcade DJ simulation music video games created by the South Korean company AmuseWorld. The game is commonly viewed as a Korean-developed counterpart to Konami's beatmania series, similar to the way Pump It Up emerged as a domestic alternative to Dance Dance Revolution. The game is known for its extreme difficulty, which increased progressively across releases and became a defining characteristic of the series, featuring dense and highly technical note charts, fast tempos, unconventional rhythm patterns, strict timing windows, and a control layout that demands advanced hand coordination, often requiring extensive memorization and many hours of practice even for experienced rhythm-game players.

== History == The first edition of EZ2DJ was introduced in 1999 and the last version, EZ2DJ Azure Expression ~Integral Composition~, was released in June 2012. Afterwards, following the lawsuit by Konami, the rights for franchise were given to Square Pixels company, and development continued under the title of EZ2AC (AC meaning Arcade), with latest version being EZ2AC Final EX, which was released in August 2020.
