One of my roommates and I tried it out at the union at school once and thought it'd be a blast to have a bunch of drunk people try at our pre-game parties for hockey. So we bought some pads for the dreamcast. After a few weeks it wasn't funny anymore, but instead it was a ton of fun, because we were getting good at it. Then I bought a PSOne and all the DDR games I could find. The most fun one was probably the Disney Mix, got it for $29.99 at EBGames, now that game goes for close to $100 on ebay! I eventually got a PS->USB converter and now I play on my mame arcade using stepmania. Haven't played in a few months, but every time I get it out, I'm usually hooked and play for weeks straight until my schedule gets busy and I don't get a chance to play.
