Playtesting a Graded Digital Roleplaying Game for Second Language Learning

Digital roleplaying games offer a promising medium for second language acquisition by providing extensive, leveled reading opportunities within an interactive framework. By applying corpus linguistics to control vocabulary and syntax, developers can create accessible, graded content that minimizes the cognitive overload often found in complex multiplayer environments. The primary objective is to bridge the gap between traditional graded readers and digital gaming, ensuring that language learners receive comprehensible input while remaining engaged through quest-based narratives.

The development of the game Just the Facts demonstrates that integrating the New General Service List and CEFR proficiency levels provides a robust foundation for linguistic scaffolding. However, technical implementation requires a delicate balance between pedagogical assessment and narrative flow. Initial playtesting with first-year university students in South Korea revealed that rigid assessment structures often lead to passive click-through behavior, where students prioritize progression over comprehension. Consequently, effective design must move away from heavy instructor intervention and toward autonomous, quest-driven mechanics that encourage deeper engagement with the text.

Future iterations of educational RPGs should prioritize longer-form content and the inclusion of non-linguistic aids to better support independent learning. While vocabulary coverage scores and frequency bands remain essential metrics for content development, they function best as flexible guidelines rather than absolute constraints. By refining in-game guidance and reducing technical friction, developers can create more immersive environments that successfully align with the principles of extensive reading, ultimately fostering greater communicative competence among language learners.
