This article investigates 8-and 9-year-old girls' use of the popular game "Minecraft" at home and school, particularly the ways in which they performatively "bring themselves into being" through talk and digital production in the social spaces of the classroom and within the game's multiplayer online world. We explore how the girls undertake practices of curatorship to display their "Minecraft" knowledge through discussion of the game, both "in world" and in face-to-face interactions, and as they assemble resources within and around the game to design, build and display their creations and share stories about their gameplay.
