Why Computer games are a phenomena that primarily interests males.

I recently read an article that was talking about how males become immersed in computer games when to a large extent females are exempt from the industry proportionatly. It suggested that the main reason was a biological one and this was basically because the part of the brain that controls hand eye coordination was larger and therefore men in general were better at things such as computer games and the part of the brain that allows people to multitask was smaller and this allowed for males to fully immerse themselves in the games. This may be the reason that for the most partt games have masculaine narratives setting and themes and video game producers have tapped into the male market more effectively and are yet to capitalize on nearly half of the population.
