T3 Entertainment’s Audition is limited to the tween audience in North America, but in Korea it’s a huge deal. The series started off as a cash-op music MMO game, spawned a PSP port and soon it’s going to be an arcade game. Audition’s concept is simple, input a series of arrows and hit the dance button to groove. Compared to other arcade games Audition has an unusually large amount of arrows to worry about. This probably isn’t for beginners, but if you’re looking for a challenge greater than Pop ‘n Music this may be worth a look.
