This chapter explores the grounding points of Indigenous game design and its potential for preserving and revitalising Indigenous cultural heritage. While digital platforms already house a growing collection of contemporary Indigenous cultural expressions such as video games, there is a lack of emphasis on preserving these games and the knowledge tied to them. The primary focus in game research has been on Indigenous video games and the analysis of their content. Without preservation efforts, these games may disappear within decades, leading to the loss of creation history and missed learning opportunities. Indigenous game design aligns with Indigenous Data Governance principles and knowledge-sharing protocols, promoting ethical and culturally rooted creation. However, ongoing discussions are necessary to ensure that community-centred game design truly benefits Indigenous people, including defining collective benefits and acknowledging community labour. The future of Indigenous game design models has the potential to preserve the knowledge in making Indigenous games.
