U.S. retail sales of video games fell 25 percent year-over-year for the month of October, according to research firm NPD. Sales dropped from $1 billion to $775 million. Hardware saw the biggest drop, nearly 37 percent from last year.

“While we saw declines in hardware unit sales across all platforms year-over-year, when looking at average sales per week versus September, several consoles realized higher sales: the 360, PS3, NDS and 3DS," said NPD analyst Liam Callahan.

"This is a sign of increasing momentum as we move into the holiday season.” Microsoft said sales of Xbox 360 reached 270,000. Sony and Nintendo did not disclose U.S. sales for October at this time.

Bethesda's new title Dishonored sold 460,200 units while 2K's XCOM: Enemy Unknown sold 114,000 units. "Due to the launch of Pokemon Black 2 and Pokemon While 2, portable software sales increased by 37% from last October," Callahan added. "However, this growth was not enough to offset declines in console software.”
