The popularization of online gaming in Vietnam, including PC and mobile gaming, has witnessed the contribution of wuxia fictions as an essential aspect of digital content production. This article shows an attempt in tracing the cultural history of wuxia works in Vietnam. East-West differences have also been taken into consideration as a way to explain reading and playing preferences. By using life course approach along with the concepts of nostalgia and cultural proximity, this study tries to historically portray the wuxia readership in Vietnam and its vestige found in wuxia online games. The findings indicate that wuxia novels serve as a crucial factor representing the literary relationship between the Sinosphere and Vietnam. Its presence has enriched the content of Vietnamese literature, adding a new genre that has been widely accepted by many generations of Vietnamese readers. Because wuxia online games could be seen as the digital continuation of wuxia fictions, the author argues that prior experience drawn from interacting with wuxia novels affects the game selection-making process of players, and gaming companies in Vietnam also acknowledge that and deploy appropriate business strategies.
