I have recently found my thesis topic.
MMOGs (Massive Multiplayer Online Games) are becoming popular in our societies. In the process, they affect our infrastructure. From learning to providing a place for socializing, participants change their life patterns, and carry out daily activities such as work, play, and relationships in different ways. Since these infrastructure build into our social fabrics, we may see it as a form of knowledge: in words, in practice, or as artifacts.
