"Time to Play" is a collaborative exploration of the concept of play in modern society, featuring a variety of independent contributions from different authors. Using the structure of a cadavre exquis (a surrealist game of assembling ideas), the book examines how play influences cities, societies, and individuals. It delves into topics such as the experience of grief in video games, the therapeutic use of play in psychiatric settings, and the phenomenon of bigorexia (obsessive sports practice). The contributors also discuss broader societal issues, like gender equality in sports, the impact of urban sports like parkour and skateboarding, and the psychological effects of addiction in casino architecture and online sports betting. In the context of the Paris 2024 Olympic Games, "Time to Play" takes a multifaceted look at how play shapes the world around us. From sacred rituals to modern sport, and from international trade to urban living, the book offers a diverse range of perspectives, allowing readers to navigate through essays, illustrations, interviews, and reports in a fragmented yet enriching reading experience. It encourages reflection on the role of play not just as leisure, but as a force that molds our cultural, social, and urban environments
