With support from the German Federal Games Funding, Ergofox GmbH developed the innovative exergame City Hopper with Nurogames as part of the BoTraCE-33 project. The game aims to prevent sedentary lifestyles and obesity by encouraging players to engage in movement-based gameplay while exploring culturally inspired environments.
