As generative AI (GenAI) becomes increasingly embedded in the game development pipeline, from character creation to procedural world-building, it brings with it both exciting possibilities and ethical challenges. This talk explores how GenAI tools are shaping the future of games, and asks: Who might be left out of what we are designing? Focusing on issues of gender, queer, neurodiversity and intersectional inclusion, this talk will examine how bias can enter at every stage of the development process and how these biases can impact both players and creators.
