The video game industry has been on fire. For twenty seven months, a streak almost unfathomable in electronics retail, the U.S. marketplace returned double digit year over year percentage growth (via NPD). Every month had yielded a more than 10% gross sales improvement, every month until now. The August NPD retail report came out this week and it showed a surprise slowdown. In August, the industry grew only 9% year over year in the U.S. Many are questioning what happened and if it's cause for concern.
