Tidal Cities was an interdisciplinary, transnational experiment that brought together an environmental anthropologist, an urban geographer, and two landscape architects/artists. We aimed at co-creating a visualization-based pedagogical tool for contemplating and teaching manifold relations between the city and the sea, drawing on ethnographic material from Metro Manila and Jakarta. The project was designed during the COVID-19 pandemic, and its digital format integrated an immersive role play component to spark further debate among tertiary students. Players were encouraged to critically reflect on and engage with trajectories and contestations around coastal planning and urban placemaking, particularly in spaces of informality beset by recurrent flooding, tenurial insecurity, and dispossession. While engaging with the poetics and politics of 2D visual representation, we reflect on the thinking behind the game´s pedagogical co-design and a number of paradoxes that arose from two test-runs with departmental students, researchers, and teaching faculty in Bremen, Germany.
