Just saw this while at work browsing MMOHut... it's finally out in English! Been waiting for over 5 years and it's finally here.
So yeah, the game is really old but has always had a huge fan base of English players playing the Korean and Japanese versions with English patch.
There's 8 playable characters in Episode 1. I believe there's another 5 or so when it goes Episode 2. The game is centered around each character's story which in the end eventually leads to each other.
