While the game industry is stagnating due to the limitations of its business model, high-quality storytelling is being considered as an alternative, and generative AI has made it possible to create storytelling. In this study, I propose a methodology for webtoon gamification, a collaboration between webtoon and game, to apply AI-based storytelling in practice. The player experience (Player eXperience, PX) in gamification is an experience befitting the player as an active agent, and the main beneficiaries of gamification, such as users, customers, guests, audiences, learners, and gamers, are proposed as ‘players’[1,2], which includes webtoon readers. This study proposes a webtoon gamification and webtoon×game collaboration type that enhances the format and expression of webtoons and the reader's experience, and also presents the commands (AI Story_Prompt) required for efficient AI storytelling, and studies the direction of convergence production between webtoons and games.
