Deathmatch games consist of anything from 2 to 32 players. I will use the term Quake to include both Quake and Quake 2 - most players have played both games, and both are still popular. To look at gender in operation in online gaming, there is not much to go on by the game itself. In Quake 1, players could only use a male model. Quake 2 came with both male and female models, and the ability to create an infinite number of other models.
Various skins are available for each model.
So with Quake 2, the software itself is ostensibly free of any gender bias. But the online playing of the game is still very much a man's world. So, to look at the operation of gender in the Quake 2 gaming experience, I conducted an email survey among the other female Quake players I could find, to get their experiences of being women who play Quake. Ten female players responded aged from 13 to over 30. Some of this harassment was directly related to sex, such as offensive name calling, demands for netsex or descriptions of the girl's physical attributes, and some was just malicious.
