MMO.. but not RPG?!
I've played Audition.. This is the American Server

I've played on the South East Asia Server but i dont think it'll be too much difference.. except for choice of songs maybe... anyway
This game... you basically try to Dance to the beats... you're given a set of arrows and you have to complete the combo within a song beat...
Anyone played Bustamove back in PS1? its like that...
Levels are just a number, it doesn't make people more powerful or anything, all clothes are just for looks, skills are based in your fingers and coordination...
Not a game for all, but if you're into beats and music.. its not a bad game!
EDIT: Oh cool! just had a look at their songs and its all English pop songs LOL! The SEA version i played are all Korean songs... i wish i can play the Nexon server
