One gets the impression that Nintendo has never been quite sure what to do with Rhythm Heaven (or Rhythm Tengoku, in Japan). Unlike their less-musical equivalent, the WarioWare series, these rhythmic minigame collections have no ubiquitous mascot character to help market the inherent weirdness within. Without that crutch, it becomes difficult to explain to all but the most Japanese-enthusiastic audience exactly what the hell is going on in any of these games. Bizarre music plays in time with even more bizarre visual scenarios, and the gameplay often revolves around just a couple of different commands over the course of the entire game. It's not a game of which the appeal can easily be summed up in a TV commercial--at least in this country.
