Model-based Systems Engineering aims at increasing consistency of information in complex engineering processes that involve different engineering domains. A major challenge when introducing Model-based Systems Engineering is to highlight the interactions of different process activities, like requirement definition, specific methods and available tools as well as roles. These interactions have to be demonstrated to members of the engineering team in order to induce awareness for potential hurdles within the implementation process and to increase acceptance for required changes of processes, methods and tools. Simulation games present a promising approach to generate awareness as well as the needed expertise for successful implementation of Model-based Systems Engineering, in both teaching of students and training of experienced engineers. In this contribution a development process and essential aspects for the game design of simulation games are proposed. The structured process and its specific steps are illustrated by the development of the simulation game MbSys
