you'd be surprised actually. a lot of girls play games.
In fact: 41 percent of gamers in Australia are women, and also 38 percent in the United States, both figures representing growth. The Herald also says that if the trend continues, it will be 1:1 guys/girls gaming by 2014.
i seen a girl PSN name with a guys voice on the mic WTF
