Computer game makers and industry analysts agree that Wii is trouncing rival video game consoles due to a captivating blend of ease, fun, family, friends and affordability.
US sales of Wii consoles with simple motion-sensing controllers last month were more than double those of Microsoft's Xbox 360 and quadruple those of Sony's languishing PlayStation 3.
Demand for Wii consoles has outpaced supply since they debuted last November. Nintendo has reportedly sold more than 2.5 million Wii consoles in North America.
French video game giant Ubisoft began working with Nintendo a year before Wii launched and premiered the sword-fighting game Red Steel at the console's release.
Ubisoft embraces the Wii platform that lets game makers get players to jump, swing, thrash and dart, according to Xavier Poix, director of the firm's Paris and Montpellier studios.
"We were convinced the first time we touched the Wii that it really was a revolution because it was a way to think of games differently," Poix said.
"When you look at someone playing an Xbox 360 game you see his face is really hard and both hands are stuck on the controller," Poix said. "When you see someone playing Wii, you always see a smile and movement. Sometimes crazy movement, but it is OK."
US video game titan Electronic Arts and the game division of entertainment icon Disney have studios devoted to making Wii games.
The release of the Disney film Pirates of the Caribbean: At World's End was accompanied by a Wii game of the same name that lets players use controllers to pretend to be sword-fighting buccaneers.
The head of the LucasArts, the game division for Star Wars series creator George Lucas, said that a Wii game that lets players wield virtual light sabers is on the horizon.
"The Wii opens up a range of creative possibilities for new and innovative game design," said Disney Interactive Studios vice president Craig Relyea.
"Our Pirates of the Caribbean game for the Wii lets you slash and thrust with the Wii remote just as someone would do using a sword for combat. We wouldn't have been able to offer those controls on any other platform," he said.
Japan-based Nintendo is cashing in on a gamble that there is a broad audience beyond the "hard-core gamers" keen on realistic warrior games rife with mayhem and bloodshed.
"Nintendo let Sony and Microsoft fight it out for the hard-core gamer market and went after all the people who either stopped playing or were intimidated by too many buttons on controllers," said video game researcher Mia Consalvo, an associate professor at Ohio University.
"It is not just a game system it is something for everyone. Nintendo is crafty," Consalvo said.
Xbox and PlayStation consoles require players to master button and toggle combinations to command onscreen characters.
"With Wii it is just intuitive," Poix said. "To move a weapon you simply move your arm."
Wii is, in a way, a family board game for the computer generation because it turns play into a community event instead of just a person versus a machine, Poix said.
"Part of the industry was misguided," Poix said. "The question was how to get people other than geeks into the market. Wii really helped us to realize we are not developing games for one type of person anymore but for everybody."
Nintendo heeded a "historical rule of video games" that consoles are hot sellers in the US$200 price range and sales cool quickly as prices rise to "nosebleed territory" above US$400, said analyst Rob Enderle of Enderle Group in Silicon Valley.
