It's been a while since we've taken a look at a Korean MMO in our Online World Atlas, despite their position as one of the most talked about segments of the MMO market. So let's take a look at one of the most famous of them – Audition, Nexon's "dance battle" MMO.

Name: Audition

Developer: T3 Entertainment and Yedang Online (published by Nexon in North America)

Established: April 2007 (in North America)

How it Works: Audition requires the download of the client (a hefty 1.6gb) which runs as an application and requires Dirext X. Navigation and gameplay are accomplished via mouse and keyboard input.

Overview: Audition is largely an online "MMO" version of dancing games like Dance Dance Revolution. In the title, players create rooms or join other players, select music and then "dance" along with it using directional keyboard commands. Players compete with each other to be the best dancer to receive rewards, and can otherwise socialize with other players.

Payment Method: Audition is free to play; players support the title through microtransactions at the cash shop.

Key Features:
- "Casual" dancing-based MMO
- Multiple modes of play
- Customizable avatars
