The accessibility of video game engines, combined with their core ability of simulating worlds, systems and rules, has cultivated a broader potential beyond entertainment products. Many of the resilient economic solidarity models we have researched at New Design Congress depend at least in part on game engines as a key component for social organising, presentation, education or value. More broadly, game engines have found application in a surprising range of disciplines, including architecture visualisation, cultural archival efforts, visual arts, urban planning and traffic simulation, education and vocational training, academia, pilot training, medical research and transportation.
