I argue that much of MMO-related scholarship is implicitly based on a dichotomous "real world vs. virtual world" model, which is heavily influenced by the "magic circle" concept in game studies. I show a number of shortcomings in this perspective and propose an alternative perspective based on Anselm Strauss's social worlds (Strauss, 1978). The alternative perspective unbundles users from the technological platform and places MMO-centered social worlds in context with other worlds like religion and workplace.
