The document discusses the history and challenges of educational games. It notes that early "edutainment" games from the 1980s-90s did not live up to expectations and game designers avoided the education genre. More recently, educational games have improved by incorporating more modern game elements and becoming more interdisciplinary. However, tensions still exist between instructional design which prioritizes learning outcomes, and game design which focuses on player experience. The document calls for better integrating the two disciplines to create engaging and effective educational games.
