USA Today reveals NPD Group's reporting $834.7 million in North American physical game sales figures for January 2013. Sales are up nine percent over the same period last year, but this is attributable to their accounting methods, rather than an actual uptick, as the results include a "leap week" that's added every few years, presumably to keep calendars in sync. Word is sales would be down 13% if this was tabulated as a typical four-week month. Likewise hardware sales are up four percent, rather than down 17%. Word is: "an additional $141 million was spend on used and rented video games, while $382 million went toward sales of digital video game content such as mobile games and downloadable content."
