This article examines two communities of youth who play an online game that integrates physical activity into virtual game play. Participating youth from two research sites--an urban middle school and a suburban junior high school--wore FitBits that tracked their physical activity and then integrated their real-world energy into game-world resource boosts. This incorporation of daily life as a mechanic of the video game creates a tangible connection between players' physical and virtual experiences. To better understand that connection, this article presents survey, GIS, and mapping data to detail the two communities as multi-domain ecologies, and then presents interview and focus group data to illustrate the players' perceptions of the affordances and limitations of their physical environments. Ultimately, the authors argue that a multi-layered analysis of real world communities is essential for designing games for health and for effectively facilitating game-based learning within players' complex ecologies.
