This is actually what got me into DDR. I am a sucker for Koji Kondo tunes, especially sped up and put to electronica ROFL.
Sure, even most of "Super Hard" isn't very tough for a DDR game, but the songs are just so much better than the weird unknown techno-shit of regular DDR.
Of course, what makes me love the game even more is its scarcity. This game can fetch up to $100 on ebay, and I got a special package that came with TWO (yes, 2!) dance pads. 2 player dancing is where its at.
I wish they'd make another one, maybe a Nintendo Mix so I can dance to LoZ and Kid Icarus, too!
