Online gaming services not only host the games, but also record the playing of the games. Apparently, the data mined from the recorded game play helps to provide the designers with ideas. Makes good sense to analyze this data, but is still a bit on the creepy side.
This is a really interesting article that I am going to discuss this week with my Computer Science classes. We are starting some game projects and this is a great lead in and conversation piece. Most all of my students play online games so I am curious to see how they respond to this article.
