As far as generic, online-Guitar Hero/Rockband-copy games go, this isn't the absolute worst one, but I wouldn't even bother calling this game mediocre. For an already annoying sub-genre based off of a monotonous, repetitive game genre, This game nears the bottom of the list. The concept of a Christmas-themed rhythm game is a bit stupid, and I'm surprised that there are already 5 of these games. The layout is distracting and makes the game more of a hassle to play fluently, the 3D animation is shoddy, and there are only a few songs to choose from.
Play at your own risk.
