Many students might spend their free time playing DOTA. Why not spend your study time doing the same? Well, in China, you can.
As That's points out, the course is called "Recent Development of Electronic Sports and Analysis of DOTA" and is limited to only 90 students. That apparently doesn't stop over 200 students from squeezing into the lecture hall.
During the course, various DOTA strategies are analysed with the goal to help students not only improve their own coordination and motivation but help inspire different ways of thinking. The implication, of course, is that these skills are beneficial and necessary in the working world, which they most certainly are!
