First off, the game is very English friendly. There is very little Korean you need to worry about other than item names, song titles, and interface, but those are pretty minor to the overall gameplay. The game starts out with a series of options such as free, standard, and network modes, a jukebox for casually listening to the music, and a collection option where you can customize your character's look, and check out various unlocks you have obtained. When you first start the game, you only have 2 stages, 20 songs, and a couple of outfits to choose from. In order to unlock more you'll need to play through the game's Standard Mode to get more unlocks.
Overall, the game is a very nice alternative for when you're not near a computer and need to get your Audition fix, or get some arrow-reading practice. The game comes with a nice collection of over 60 songs along with some exclusives not found in the online game from artists like Sweet Box, XR, The Gold, and Wa Wa. If you are lucky enough to find yourself a copy of this rare game and you love the online game, I highly suggest you grab it while you can. It is a nice alternative to the online game and also gives you a taste of what the gameplay interface looked like before all the graphical updates you see today!
