On October 5, 2023, Ubisoft Entertainment SA (Ubisoft) released Assassin’s Creed Mirage, the thirteenth installment in its video-game series launched in 2007. Since its inception, the Assassin’s Creed franchise has engaged hundreds of millions of players around the world; the most recent estimates indicate that Mirage players number in the millions.1 Set in 9th-century Baghdad, the game centers on Basim Ibn Ishaq, a character introduced in Assassin’s Creed Valhalla (2020). The authors of this article served as consultants and collaborators for the game, under the auspices of the Digital Lab for Islamic Culture and Collections (DLIVCC), based at the University of Edinburgh. As such, we were among the external historians and institutions who helped create and contribute to the game’s educational feature.2 This article offers reflections on our collective experiences working on Assassin’s Creed Mirage, reviews historical representation of Islamicate cultures in video games, discusses the remit of the DLIVCC consultancy, and identifies some structural challenges to diversifying and decolonizing video games and game-development processes.3 Lastly, we propose steps for scholars and institutions wishing to broaden the impact of their research through decolonization work across the academic, video games, and GLAM (Galleries, Libraries, Archives, Museums) sectors.
