This study investigates serious games as a tool for organizational learning and the extent to which they can enable managers to understand, learn, and develop knowledge about urban innovations. In particular, we aim to determine whether serious games can be a substitute for traditional market exploration or traditional organizational training and enable managers to learn about sustainable innovations, such as smart cities. To answer this research question, we constructed a database through the design and creation of a serious game on smart cities for the business managers of the French subsidiary of a multinational company operating in the construction and energy sector and, through a questionnaire, collected data on the manager's post-game learning experience along with their characteristics. The analysis of the overall database enabled us to draw a set of results with both theoretical and managerial implications. The main contribution of this paper is to test the pertinence of serious games as a tool to address a pressing need for organizational learning about sustainable innovations.
