I spent a lot of my misguided youth playing video games into the late hours of the night. It was how I found solace in times of pain or loneliness. Because you can’t see another person physically when playing games — only their avatar — you really can’t tell what race someone might be. Certainly you can make informed guesses based on things you might learn about them, their culture, or the language they speak, but nobody can know unless you tell them. Not having visual perception makes for interesting interactions. It highlights some of the inherent biological biases people have, and the fact that it is something we should strive to overcome.
