Now his study on City of Heroes/Villains is finally coming forward, revealing a controversial look at how defying the cultural rules of a population can turn a person into a social outcast. The study's goal was to play only by the developer's rules, ignoring any extra rules that might be created by the population. For example, the concept of "kill stealing" and "fair fights" are thrown out the window as they are created by the population, not the game. Think of it like EVE Online -- if the game allows it, he does it.
While the study is intriguing in the fact that it covers the "new frontiers" of virtual worlds, it also brings into question some of the ethics involved with working undercover in a population, such as causing undue stress via what we consider to be griefing.
