This document summarizes a roundtable discussion on gamification from game studies and HCI perspectives. It provides an introduction and overview of the pre-history of gamification in HCI, current topics being discussed, attempts to define gamification, and plans to debate focal questions. The roundtable covered the diversity of gamification applications, attempts to make sense of gamification through different theories and frameworks, and discussion topics around ethics, user groups, design challenges, and player behavior. The goal was to discuss what is new and valuable from an HCI perspective, how gamification has been approached in game studies, and what opportunities it provides for future game research.
