The best-selling game in October was Microsoft's "Fable II" for its Xbox 360 console, which sold 790,000 units, according to NPD. In second place was Nintendo's "Wii Fit," which sold 487,000 units. "Fallout 3" from Bethesda Software for the Xbox 360 came in third at 375,000 units, followed by "Mario Kart Wii" and "Wii Play" to round out the top five.

The highest-ranking game for Sony's PlayStation 3 was "Socom: U.S. Navy Seals Confrontation," which came in seventh place with sales of 231,000 units.

In hardware, Nintendo's Wii outsold its nearest competitor by more than two-to-one with sales of 803,000 units. That made October the console's third-best-selling month yet, after November and December last year.

The Xbox 360 sold 371,000 units and the PlayStation 3 sold 190,000 units. While the PlayStation 3 remains in third place, the sales increase it achieved over October 2007 was 57 percent, significantly higher than the gains recorded by the other consoles.

Sony's older PlayStation 2 managed sales of 136,000 units. The console is still popular because of its low price and the wide variety of software available for it.
