In Ireland, a large longitudinal study of children has indicated that over half of nine-year old children are playing video games daily, while the international adolescence literature indicates that the rate of game play is growing year on year (Gentile, 2008).

The exposure of young people to violent video games may be viewed within the context of risk factors for the development of aggression, and as such an understanding of the research within this area may be paramount to allow a full consideration of levels of "exposure" to such a risk. Variables that may impact on the usage and effects of violent video game use are discussed, such as developmental stages, gender, individual characteristics, culture and game structure and content. Recommendations from key research in relation to monitoring of video game usage are also discussed.
