To add to your post I attended a school based on the summer hill philosophy and one of the reasons all the students went to class was because the whole school set up the timetable democratically at the start of each semester.
This led to some interesting subjects like yoga and womans rights but it also provided subjects of interest to nearly all the students so there was more desire to attend and learn.
An additional bonus of this kind of system is that often subjects like computer games development require some grounding in maths which makes these kinds of abstract subjects more desirable.
It was also clear that these core subjects are requirements for further education so there was always enough desire from people wishing to attend university to keep the core subjects going.
