Here's Miami's description of their program. Seems like it has mostly to do with training in how to run and market tournaments. Since that school is a complete non-entity in engineering or computer science, I guess that makes sense.
An Esports Management program turns your passion for gaming into an exciting career. Miami University’s Master of Esports Management degree — available both online and hybrid — gives you a solid foundation in all esports functions, including tournament and facility management, branding/marketing, sponsorship, team management, performance psychology and coaching, recruiting, finance, business models, media rights/legal broadcasting and more. In addition to the two semesters of online coursework, our Esports Management program features a brief in-person residency where students gain hands-on experience assisting with a top-ranked tournament organization.
What's next at Miami? A bachelor's degree in preppy studies?
