Game based approaches and especially gamification are an emerging topic within the field of motivational design at the workplace. The motivational potential of games was suggested to be based in motivational psychology. So far this is an active field of research and has not been established in theory. Only limited research on actual design practices and tools is available. In this paper we present empirical results of 28 interviews conducted on workplace motivation and player motivation practices in game design. Hence, we suggest a design card deck connecting the two disciplines. The work aims to support the idea and creation processes of game related motivational design tasks in enterprises and raise awareness for the individuals? needs and motivations. Reflections with field experts and a focus group test resulted in useful suggestions for further development.
