      Ko spins, swivels, slides and stomps his way across a floor lit up with 
      red and blue flashing arrows, his feet moving to the rhythm of pulsating 
      techno music. 
      Ko, 21, isn't showing off his fancy footwork at a local 
      nightclub. The UC-Berkeley senior has never set foot in a club. ``I can't 
      dance,'' he claims. 
      But Ko gets his groove on when he plays Dance Dance Revolution. 
      
The arcade game Dance Dance Revolution, or DDR, is the days of disco 
      dance parties reincarnated. By breaking with the tradition of 
      joystick-controlled fighting games geared toward males, DDR lures new 
      audiences into arcades as the dancing phenomenon glides across continents 
      on the crest of the music-based video game wave. 
      
DDR requires players to use their feet to press four arrows -- up, 
      down, left, right -- on a dance pad. Hip hop, dance pop, rave or '70s 
      songs blare as a sequence of arrows float to the top of the screen, 
      prompting the player to step on the corresponding arrows to the music's 
      beat. 
      
The game is the latest pop revolution from the country that brought us 
      karaoke. 
      
Konami Co., a leading video game developer based in Tokyo, unleashed 
      the dance simulation craze when it introduced DDR to arcades throughout 
      Japan in October 1998. The game -- which comes in a video game format for 
      the Japanese version of the Sony PlayStation and Sega Dreamcast consoles 
      -- made its way throughout Asia shortly after and to America's shores last 
      summer, but appearing only in arcades. 
      
Even though DDR is relatively old by industry standards, it continues 
      to command rave reviews. The fourth version of the popular game is 
      scheduled to hit arcades in Asia next month. 
      
In September, Konami plans to release a version for American arcades: 
      DDR USA Mix, which will feature a new collection of songs drawn from the 
      first three Japanese mixes. 
      
Currently, gamers in the United States can only buy the dancing game 
      for the Japanese models of PlayStation or Dreamcast -- hunting them down 
      at import stores or asking friends who travel to Japan to bring it back. 
      The lag time between a game's release in Japan and its arrival in the 
      United States ranges from a month to a year, but Konami has hesitated even 
      longer in introducing DDR for American home entertainment systems because 
      other music games have not sold too well here, said Jason Enos, product 
      marketing manager for Konami of America Inc. in Redwood City. 
      
PlayStation's PaRappa the Rapper, the most successful game in this 
      genre, sold only 250,000 units since emerging on the U.S. market in 
      November 1997, according to The NPD Group, a market research firm based in 
      New York. That isn't a screaming success considering there are more than 
      25 million households in America with a PlayStation. 
      
But now that the game's arcade debut has players begging for an encore, 
      Konami said it is considering releasing DDR for the American version of 
      PlayStation in the near future. 
      
``Since Dance Dance Revolution has made it to the American arcade, we 
      have received hundreds of letters and e-mails from fans wondering why the 
      home versions aren't out as they are in Japan,'' Enos said. ``We're 
      definitely taking the feedback that we get from the fans.'' 
      
Fewer than a dozen states have an arcade with DDR, but the game has 
      gathered a cult following, especially on the West Coast, where dance music 
      and rave culture are all the rage, Enos said. 
      
Dance Dance Revolution fans at UC-Berkeley and UCLA created Web sites 
      for fellow enthusiasts, and video clips of impressive routines can be 
      downloaded from the Internet. Gamers asked Playland Arcade at Santa Monica 
      Pier to hold a DDR competition last month, attracting 50 entrants, 
      including about a dozen players from Northern California. 
      
The game is deceptively simple for beginners, especially for those 
      whose agile feet are weighed down by the burden of self-consciousness. But 
      even the flashiest DDR players admit to freezing with stage-fright when 
      they experiment with the game in front of the crowds that undoubtedly 
      form. 
      
DDR is more than a video game -- it's a spectator sport. Dozens of 
      people flock around the machine, often mesmerized by the creative flair 
      and acrobatic stunts that spice up a seasoned player's dance routine. 
      
The objective of Dance Dance Revolution is not only to earn a high 
      score by methodically stepping on the correct arrows at precisely the 
      right moments; this game is also about strutting your stuff. 
      
Dancing duo Anthony Bui, 14, and his brother, Eric, 12, of San Jose, 
      choreograph performances for the two-player mode of DDR. They throw in 
      cartwheels, slam the floor panels with their hands and knees and 
      continuously switch places -- all while hitting the arrows on cue in what 
      arcade regulars call the brothers' ``trademark song.'' 
      
But you don't have to be a disco king to attract attention with DDR. 
      Arcade managers note that even novices draw crowds. ``We've had an excess 
      of 50 people watching. It looks like there's a line just to watch,'' said 
      Heath Nielsen, senior manager of business operations at Sony Metreon in 
      San Francisco. 
      
Konami's line of music-based video games -- primarily DDR and Beatmania 
      -- has sent the company's net income for the fiscal year ending March 31 
      soaring nearly 260 percent to 18.3 billion yen, or $173.6 billion, up from 
      5.1 billion yen, or $48.4 billion. 
      
Now the music trend has swept up other game developers. Last month, 
      Sega released Space Channel 5 for Dreamcast, a game requiring players to 
      tap the given rhythm on a handheld controller. In the fall, Sega will 
      introduce gamers to Sambadeamigo, a full-body interactive game like DDR -- 
      except players shake maracas to Latin music. 
      
So who plays Dance Dance Revolution? 
      
Everybody. 
      
``I've seen grandmothers and grandfathers on that thing,'' said Tim 
      Robinson, a manager at Camelot Park, a family entertainment center in 
      Fresno. 
      
Some DDR gamers admit they started playing in hopes of learning how to 
      dance. Others gave it a try because it looked easy. 
      
``You don't have to be very coordinated. You just have to be 
      dedicated,'' said 20-year-old Doreen Toy of Milpitas, confessing that she 
      trips over her own feet. 
      
Several players practice hip-hopping to DDR's songs on their home 
      entertainment systems. But once they memorize the timing and sequence of 
      arrows, they shove the game under their beds and head to the game center 
      because nothing beats the arcade environment. Calvin Ling, 17, of San 
      Jose, said he rarely plays at home anymore because the dance pad slips and 
      the family room carpet absorbs every step. 
      
Still, others view the household game as a reason to celebrate. A few 
      weeks ago, Mayene de Leon, 12, and her brother Cynan, 22, of Antioch 
      rounded up 20 of their closest friends for a DDR party in their garage. 
      They boogied for 12 hours non-stop on PlayStation and Dreamcast. 
      
But DDR isn't just fun and games. It's also an exercise regimen. 
      
Nattie Saggie, owner of Network Video Inc., an import video game 
      retailer in Burlingame, starts her day by playing DDR for at least 20 
      minutes. 
      
``I've lost a good 10 pounds,'' said Saggie, 45, who got hooked on the 
      game in March. ``It really tones up the body.'' 
      
Hard-core DDR players work up such a sweat during the eight-minute game 
      that they're longing for a towel and a bottle of water when the workout 
      ends. 
      
After noticing this, game developers added a ``diet mode'' so players 
      can keep track of how many calories they burn while mimicking the dance 
      steps in the newly released DDR 3rd Mix for the Japanese version of 
      PlayStation. 
      
Because DDR is only available under its Japanese title, most video game 
      retailers -- including Toys R Us, KB Toys and Electronics Boutique -- 
      currently don't carry it. 
      
However, die-hard DDR fans in the United States looking for the video 
      game can get their hands on it at an import store or online. Many 
      PlayStation and Dreamcast owners said they don't mind paying the $50 to 
      $60 for the special chip required to adapt their entertainment systems for 
      Japanese video games. Nor do they think twice about paying the pricey 
      import costs for the $60 game and the $75 dance pad, which are sold 
      separately. The trick is finding a retailer that has those items in stock. 
      
Since DDR hit the Japanese home market last year, Network Video has 
      sold 600 units of the game, in various editions, in the United States and 
      more than 10,000 mats -- a discrepancy attributed to the high piracy rate 
      of PlayStation CDs. 
      
Toy said she bought a burned copy of Dance Dance Revolution on eBay a 
      few weeks ago because the availability of originals is so low that ``you 
      just take what you can get.'' The San Jose State University senior, who 
      grew addicted to DDR with her daily fix of the game at the Milpitas 
      Golfland since summer vacation began in May, now gets a second dose each 
      night at home. ``I can't stop.''
