Player data has become a crucial element in game development and research. However, its direct integration as a diegetic element within games remains largely unexplored. This paper aims to inspire the games community by highlighting the potential of using player data for creating new interactions and play experiences. We raise technical, design, psychological, and ethical questions and argue for using player data more boldly and ambitiously, empowering players to shape their experiences and the game through their own data. By doing so, data transforms from being an analytical to a creative asset, seamlessly enhancing the exchange between games and players.
