Discourse on the global games industry draws attention to the growth of China, in terms of both its consumer market and the games publishing landscape. Trade associations and government agencies have sought routes for Western games studios, publishers, and rights holders to connect with similar organisations in China. However, there has been limited focus on how Western and Chinese game developers understand and navigate the challenges of transnational collaboration and creativity in games production. This article presents a case study of five transnational game development teams, all of which were composed predominantly of developers from the UK and China who were tasked with producing game prototypes for both markets. Data gathered during game production included development diaries, interview data, game prototypes, and production documentation. Three themes emerged from analysis of the data: production practices and transnational working, navigating regulations and restrictions, and market and cultural differences. Findings highlight that developers encounter challenges around political and cultural difference that could inhibit production or lead to uncertainties in design decision making, but also that developers can quickly establish routes to collaboration and knowledge sharing that can help to overcome these barriers.
