Adelyne Chan completed this course, spending 4 hours a week on it and found the course difficulty to be hard.
A slightly harder and more confusing version of Competitive Strategy - whilst not formally requiring CS as a prerequisite I did find this course quite difficult even having done the beginner version.
Overall the material was still very well presented and Prof Tobias and his team make a lot of effort both in the videos and in the forums to ensure ample understanding by students. Videos are also timed optimally to maximise learning capabilities. Perhaps it would help if, like some other courses, a recommended textbook or some supporting text were prescribed to support the lectures.
