“[G]enerally speaking, the more ‘hardcore’ the gamer, the more likely he is to be male, and conversely, the casual gamer will tend to skew female.”

This article gives a brief description of gamer demographics, specifically the break down of what gender typically plays what game. It was written in 2007 and the statistics are from 2006 – right around the same time A Casual Revolution was written.  I’m wondering how these demographics have shifted in the last five to six years. My speculation is that casual gaming has become equally popular between males and females over time, but hardcore gaming has become more male dominated.
