To provide some context for PC gaming, an examination of core PC (e.g. Steam) gamers suggests that the market is still largely male (65%), with male gamers tending to be slightly heavier players/payers than females (58% of men are heavy players/payers, compared to 40% of women). Despite this difference in investment, there is a heavy degree of overlap in genre preferences - with RPGs, MMORPGs and Strategy games being among players' top five genres.
