U.S. video games sales were down slightly in September, according to data from research firm NPD Group. Sales of hardware, software and accessories dropped 7 percent from the year-ago period to $1.27 billion. “This is the first true monthly decline the industry has experienced since March of 2006. It’s important to keep in mind, however, that this month’s 7 percent decline is against a month that itself was up 75 percent from the prior September,” said Anita Frazier, an NPD analyst.
