I thought about this one when I saw your thread about first person shooters.
Yeah, its a great exception, it and bishi, bashi special, I think the Japanese market is awesome and the sorts of weird games they create are a vital break with the western world's FPS singularity, you should read about some of the completely mad games from the atari and early nintendo era that the Japanese wanted to create but didnt get to.
There's also some disgusting examples, the was one in which you emulated with a big plastic hand shoving a finger up someone's butt! I mean WTF.
