This paper presents insights about design practices that can lead to effective and fun games for learning, gleaned from interviews with experienced game developers. We based our approach on Schön’s notion of practitioners evolving shared ‘appreciation systems’ for discussing and critiquing work, and aimed to gather and share some of game designers’ ‘appreciation system’ for games and learning. The resulting insights provide valuable pointers to other designers in the CHI community crafting game-like experiences. Author Keywords Game design, design patterns, games for learning, appreciation system, games and education, design practice. ACM Classification Keywords H5.m. Information interfaces and presentation (e.g., HCI): Miscellaneous. General Terms Design, Human Factors.
