Over the past 3 years, the authors have pursued unique cross-college collaboration. They have hosted a National Endowment for the Humanities (NEH)-funded Humanities Gaming Institute and team-taught a cross-listed course that brought together students from the humanities and computer science. Currently, they are overseeing the development of an NEH-supported social history game called "Desperate Fishwives". In the process, the authors have realized that "game" is not the most appropriate designator for the kind of projects they are pursuing. Instead, they propose "critical interactives", a term that suggests projects that mobilize ludic methods in order to engage participants in socially and politically sensitive, indeed controversial, subject matter. Their most recent project, "Ghosts of the Horseshoe", offers an initial look at how critical interactives are particularly apt at raising awareness about the relations among institutional policy, broader public policy, and the ways that people negotiate the public history of a particular place.
