As a bullet point outline, summarize the contents of this text.

Last week, shortly after a Wii review unit arrived at Forbes.com's office, I set it up in a conference room to test it out. A colleague and I booted up Wii Sports, a collection of simple sports games that comes bundled with every console. It wasn't long before we were completely immersed in Wii Tennis. The simple mini-game replicates an actual tennis match as well as any I've ever seen: Since you're actually swinging the remote like you would a racket, you can hit with varying force or apply spin to the ball, depending on how you move your body.

Within minutes, we'd drawn a crowd, and only a short while after that, most of the editorial staff was packed into the conference room, laughing, enjoying the show and pushing for their turn at the remote. It was the first time since the original Nintendo Entertainment System came out in 1985 that videogaming felt like a party experience--not just because it was new, and worth gawking at, but because the experience is so much more physical, like Charades or Twister, and spectators can enjoy as much as the players.

After the hard-core gamers got their turns, less videogame-savvy editors took a shot, too. And it was here where the intuitive motion control system really proved its worth. There's no sequence of arcane button combinations required to throw a baseball: You just wind up and mime an actual throw. Suddenly, videogames are fun for everyone--old or young, male or female, regardless of prior gaming experience. I lost count of how many times I heard non-gamers say, "Wow, I want to get this."

The other phrase I heard a lot was something to the effect of, "There's no way I'm shelling out all that cash for a PlayStation 3." Sony's new game console, which debuts Nov. 17 in the U.S., will retail for $500 or $600, depending on whether you buy a basic setup or the premium version, which comes with a bigger hard drive, built-in Wi-Fi and a flash memory card reader. Similarly, Microsoft's Xbox 360, which debuted in November 2005, now retails at $300 or $400.

Compare that to the Wii's $250 price tag, and Nintendo's already got a leg up in the upcoming console war. By concentrating on innovating through game play, and ignoring its competitors' most high-tech features--super-powered processors, support for high-definition televisions and DVD formats--Nintendo has not only been able to keep its costs down, but it's hit upon the single thing that sets apart an entertainment device most: It's fun.
