I read an article several years ago (I cannot remember the source), where someone cited all the complexity of managing a corporation (logistics, interpersonal relations, leadership, finances, etc.) had a lot of skills in common with "real-life" job skills and running a business. It was very detailed and showed the intricacy of building a viable corporation as well as real-life business.
The sheer nearly-unlimited potential of the player-base has become a source of continuing interest since.
