I'm very happy to meet this point of view. I'm currently working as Engineering Manager in one of the biggest corporations, this is a whole new world of challenges and a place where products you use every day are build.
I'm building a game that will represent my job in game form with all the important aspects of doing this work. As you mentioned in the talk, It will be a playground to safely explore what needs to be done to be a good manager and what you have to know about it for transition from engineers to manager. Ambitious goal for future is actually to emulate the corporation.
So, I support the idea that games are medium for people grow and I'm betting on this with my project.
