MIT pioneered the gifting of teaching resources years ago, making much of their undergraduate materials available online for the general public. More recently, MIT's Sloan School of Management has released a great deal of case study material. In effect, any entrpeneur can now partake of the learnings that these case studies offer:

MIT Sloan Teaching Innovation Resources (MSTIR) is a collection of teaching materials, including case studies, simulations, deep dives, and industry, business and country overviews that MIT Sloan provides as a free teaching resource open and available to the world.....

...The various materials posted on this site have been developed by MIT Sloan faculty and students.  Although the collection covers a wide array of companies and organizations, industries, and geographies, it focuses on areas in which MIT Sloan’s innovative research and teaching are on the cutting edge and for which teaching materials are not as widely available as in more standard areas of management.  These areas currently include sustainability, industry evolution, and global entrepreneurship.

I always wanted to get an MBA. This is a small substitute, but I'll take it. The paper on Sony's Battle for Video Game Supremacy seems like a good place to start.
