The objective of this paper is to contribute to discourse informing the use of computer games in Global Citizenship and Development Education. In doing so, it addresses the incompatibility and conflict between the values imbedded in games and those informing development education practice. It is aimed at both formal and informal educators who see the potential in using games in their practice and want to reconcile this dilemma. It is also aimed at policy makers and influencers who want to shape the structures governing such digital spaces in the public interest. The research involved an interdisciplinary literature review across the fields of Education, Game Design, colonialism and social activism. The analysis takes a postcolonial perspective and is informed by the theory and practice of critical pedagogy in youth work and development education. The study was conducted as part of Doctoral research and project work with NGOs over a seven-year period to 2024. In this context it is important to note that this is a rapidly changing and evolving sector. The development of computer games and immersive technologies over the past 20 years has been transformational, in their interactive capabilities and global proliferation, particularly with the emergence of “The Metaverse”. Such expansion has been critiqued as a process of Colonialism, where young people’s time, creativity, identities and attention is being commodified, monetised, packaged and sold to the highest bidder. The structure of the games industry, their content and the ecosystem surrounding gaming are all ideologically driven. Such ideology aligns with one of three systems: the neoliberal hegemony emanating from transnational corporations and market economies; the state control being exerted by China and others; or a blind commitment to opensource being advocated by many industry innovators, developers and users. When using games in an educational context, and particularly when addressing Social Justice and Global Citizenship, the values and cultures underpinning all three of these ideologies are problematic. It is the contention in this paper that such spaces can also be developed as informal educational spaces informed by values aligned with critical global citizenship and development education. Now is the time for development educational practitioners, conscientious games designers and policymakers to collaborate, to act, to legislate, to experiment and carve out a safe, progressive, dynamic, decolonised digital space for engagement with issues of global citizenship and development education
