EM-Power is a simulation game in which players need to spend a limited amount of funds to build and maintain power stations, transformer substations, distributing stations and other facilities on Mars in order to ensure continuous and stable power supply. Players are expected to learn some basic knowledge of power engineering in the gaming process. This game was created by a team of Yanqu Chen, Shiyu Liu, Chenyi Wang and Hao Xu. It is the outcome of Design Studio 5, one of my courses in the autumn semester of 2022. The Social Value Research Institute of Tencent Interactive Entertainment supported and participated in the course.
