Sales of gaming software declined 29 percent to $625.79 million, with Activision's Prototype topping the charts with 419,900 units sold. THQ's UFC 2009 Undisputed title took second place with 338,300 units sold, while the EA Sports Active title for the Wii came in third with 289,100 sales.
"The video games industry realized a significant decline when compared to June 2008, the fourth consecutive month of year-over-year declines," said NPD analyst Anita Fraizer in a statement. "The first half of the year has been tough largely due to comparisons against a stellar first half performance last year, but still, this level of decline is certainly going to cause some pain and reflection in the industry."
