NPD’s game industry report for October shows a precipitous 19 percent decline in sales compared to the same month last year, reports Industry Gamers. Both hardware and software contributed to the decline, with hardware down 23 percent and game sales falling by 18 percent. Year-to-date sales are now down 13 percent compared to the same period in 2008.

Nintendo systems led the hardware category for the month, with 507,000 units sold for Wii and 458,000 for DS. Sony trailed with about 321,000 units of PS3, while Microsoft managed just fewer than 250,000 units of Xbox 360.

Top game sellers were Sony’s Uncharted 2: Among Thieves with 537,000 units, Nintendo’s Wii Fit Plus with 441,000 units, and Take-Two’s Borderlands selling 418,000 units.
