And now, Sony vs. Nintendo vs. Microsoft.
In a video game industry that has experienced a rush of popularity and an explosion of profits in recent years, these three companies are fighting a war of business deals and bottom lines. Sony's Playstation 2, Nintendo's GameCube and Microsoft's Xbox have been duking it out for consumer dollars.
The greatest success story for Xbox so far has been "Halo," a smash-hit first-person shooter with a man-versus-alien storyline. Nintendo's "Super Mario Sunshine" is the latest vehicle for the beloved Italian plumber. Sony's system has seen many first-class games come its way -- "Gran Turismo 3 A-Spec," "Final Fantasy X" and "Grand Theft Auto 3" have brought favorable reviews and huge sales.
Games are like bombs in this industry -- the really good ones can sell hardware for one company while cutting into the sales of the other two. At times, the console wars have proved to be especially costly for the participants.
Sega, whose Genesis console battled the Super Nintendo Entertainment System for top dollar in the early 1990s, recently gave up the console fight and switched its focus to making games. The Sega Dreamcast had been eclipsed by the next-generation systems of Sony, Nintendo and Microsoft.
"They were leaking money like a sieve," said David Smith, PSX/PS2 editor for IGN.com. "Over the life of the Dreamcast, Sega repeatedly required massive cash infusions from its parent company to stay in business.
"Microsoft is in the same position, in a way, but the difference there is that Microsoft can blow all the money it wants on a long-term gamble."
With the Xbox, Bill Gates and company have shot for the moon on their first try. The system's hardware is more capable than that of the Playstation 2 and the GameCube. But in this war, allied support is just as effective as the power of a company's weaponry. At this point, Sony has the largest game library and the success of its first Playstation to help the PS2.
"This generation has shown, more than anything else, the power of an established brand as opposed to an immediate advertising campaign," Smith said. "People seem to have bought the Playstation 2 almost out of reflex. That was the brand they trusted."
